INTRODUCTION

The CS8 console has been designed to provide the consultant,contractor, installer and user with a cost effective system whichwill perform to accepted professional standards, be simple for theuntrained user to operate, and be tolerant of wiring and installationproblems. There can be no excuse for a system which is over sensitiveto the wiring and installation conventions used, and hums at everyopportunity.

High quality balanced inputs and outputs are only part of the story.Equally important is the way in which the console grounding systemworks, because it is through the console ground that all the noisyground currents from the cable screens will flow. Any part of theaudio signal path which shares the cable screen to console groundpath within the console will effectively have the cable screen noiseadded to that signal path. The current flowing in cable shields intypical installations has be shown to be substantial (in the order of100mA and above) and is caused by the difference in potentialbetween the ground connection at each end of the cable screens.

Of comparable importance to any system performance is the powersupply. Internal linear power supplies may be less expensive, butare usually responsible for inducing noise into the audio andgenerating substantial amounts of heat, making it uncomfortablefor the operator. Internal switch mode supplies may be cool running,but are usually even more of a problem with regard to noise.Another often overlooked point with internal power supplies ishow to provide auto-switchover between 2 supplies withoutextensive modification thereby nullifying the warranty. Internalsupplies are also a potential problem from a maintenance point ofview.

Most service technicians can easily fault find and repair a linearsupply with commonly found components, but a switch mode supplydoes not make use of common off the shelf components. Althoughmore expensive, a separate and generously rated linear powersupply is used with the CS8 keeping heat and noise away from theconsole. Rack mounting ears are available for permanentinstallations, and the supply is UL and CSA approved.

At this point it is useful to look at some of the features of the CS8.

PAN AND ROUTINGThe pan pot can be switched between stereo panning mode, andleft/centre/right panning mode. Left-centre-right panning to themaster outputs provides much improved spatial positioning. Thetechnique has been used for many years in the film industry whereits benefits are well known.

5

In music systems the centre channel generates a more solid centreimage, especially for the “star” of the show, and helps to maintaina stereo image across a wider sound stage. In mixed mediaproductions and in church applications the use of a speech optimisedcentre cluster can improve intelligibility without compromising themusic system performance.

If only a stereo system is being run, and the pan pot is switched tostereo mode, then the centre output is individually assignable fromeach input or the from a sum of the left/right mix to provide aseparate mono output for broadcast/film feeds etc.

Another unique feature for a mixer in this class is individual subgroup routing instead of the inconvenient and inflexible pairedrouting which always requires the use of the pan pot to route achannel to a single sub group. There is always a crosstalkperformance compromise involved and it is done solely for economicrather than for operational reasons, as it halves the number ofrouting switches and removes the need for a pan in/out switch.The CS8 allows routing to the sub groups either individually or inpairs via the pan pot.

EQUALISATIONThe CS8 input module has a 4 band equaliser with high and lowfrequency boost/cut controls and two swept frequency middlesections. There is more than two octaves of overlap between thefrequency ranges of the mid equalisers while the frequency spanextends to from 70Hz to 10kHz.

AUXILIARIESThe CS8 has 8 full time auxiliary send controls allowing easy sessionsetup. These are normally post fade but can be switched pre fade.Normally the pre fade signal is pre fade post cut but byusing internallinks it can be changed to the pre equaliser signal. Auxiliaries 7 and8 can be used in stereo where stereo foldback, for example, isrequired.

CHANNEL CUTThe channel cut is a silent FET switch which can be remotelycontrolled through a connector on the rear of each channel by asimple connection to ground. In addition, when the channel cutswitch is pressed, another contact is grounded on the Mute Remoteconnector. This can be used to control a Midi Mute controller, cuelights, or even to control another channel on the mixer by linkingthe mute out pin of one channel to the mute in pin of any otherchannel(s). Such an application could be a podium switch whichwould allow the speaker to override other channels for example.

6

SOLO/PFL MONITORINGWhile it is normal to find PFL/AFL on almost all mixers, the CS8goes a step further. The input solo is arranged to have priority overthe output solo. This means that there is no need to de-select anoutput solo when selecting one or more input solo controls, andwhen the input solo is released, the output solo is re-established. Amaster solo level trim control is located on the master module forlevel matching, and the level of the solo signal is displayed on theleft mix bargraph.

An additional solo feature provided is Solo In Place. In this mode,soloing any input channel will cause all other input channels to becut, thereby allowing only itself to be heard in the mix, correctlypanned and at the right level, along with any stereo effect returnchannels. This is of great benefit during set-up and rehearsal and ismuch more useful than the standard PFL. A switch on the mastermodule selects Solo In Place mode.

SIGNAL LED’sThe value of effective metering of signal levels throughout thesignal path cannot be overestimated. Signal present and 0dB LED’son all input channels give confidence to the operator while peakoverload LED’s indicate when the channel is being driven close toclipping. However, it is unusual to find a peak overload LED at thevery place where it is most needed, at the summing bus mixamplifiers, operating independently of the output meters. If themix amplifier is overloaded and starts to clip, the only thing thatcan be done to rectify the situation is to pull down all input faders.On the CS8, there are overload warning LED’s on each of the subgroup mix amplifiers as well as on the left, centre and right mixamplifiers. When the output meters are switched to observe thematrix outputs the bus peak leds also monitor the matrix bus.

INSERTSInserts are used to patch in external pieces of equipment such asequalisers, limiters etc. and are provided on all channels, groupoutputs, mix outputs and auxiliary outputs. To be useful anduseable, the inserts should be at a level which is compatible withthis external equipment. Sadly, this is often not the case. Somemixers have inserts at odd levels which will preclude their efficientuse because of the noise penalty. All inserts on the CS8 are at aconsistent level which is at the internal operating level of 0dBu.

AUXILIARY INSERTSIn most installations, it is quite normal to place an equaliser in thestage monitor sends, but this is normally external to the mixer. Thisof course means that the only way of listening to the monitor sends(internal to the mixer) is via the solo system.

7

Herein lies a problem. The operator does not hear the effect of theexternal equalisation. Also, any noise introduced by the externaldevice is constant and not proportional to the setting of the sendcontrol. The ideal place to insert an external device is pre the sendmaster control and this is the case in the CS8.

INSTALLATION GUIDE

There are a number of points to consider when installing a mixingconsole. Many of these points will have been addressed before theconsole is even unpacked but it is worth repeating them again.

POSITIONThe console should be located in a convenient space commensuratewith the use to which the console is being put. Ideally a cool area ispreferred not in close proximity to power distribution equipmentor other potential sources of interference. Provision should be madefor some flat surface surrounding the console to prevent peopleusing it as a table top. One of the worst fates that can befall aconsole is for a cup of coffee to be tipped into it by someone restingit on the control surface!

POWERThe power supply should be located as far from the console as theconnecting cable will allow, a 5 metre power cable is supplied withthe console. It should be set for the appropriate line voltage andplugged into the mains outlet using the supplied cable. If the powersupply is rack mounted then be sure to leave space above forventilation - 2U is suggested.

ATTENTION

CABLESThis product should only be used with high quality, screened twistedpair audio cables, terminated with metal bodied 3-pin XLRconnectors. The cable shield should be connected to Pin 1. Anyother cable type or configuration for the audio signals may resultin degraded performance due to electromagnetic interference.

ELECTRIC FIELDSShould this product be used in an electromagnetic field that isamplitude modulated by an audio frequency signal (20Hz - 20kHz),the signal to noise ratio may be degraded. Degradation of up to60dB at a frequency corresponding to the modulation signal maybe experienced under extreme conditions (3V/m, 90% modulation).

No permanent damage or degradation of performance will becaused by these conditions.

WIRINGThe console uses four different connector styles:-TRS jack sockets, XLR male connectors, XLR female connectors andphono connectors.

The cables used should be of as high a quality as possible. Manyinstallation problems can be traced back to poor or faulty cablesand connectors.

There are two different conventions for the wiring of XLRconnectors. The international convention uses pin 2 as the hot pinwhile the older American convention uses pin 3 as the hot pin.When going from balanced input to balanced output this is of littleconsequence but when unbalanced signals such as those found onthe insert points are used then phase reversal can result. The CS8and all DDA products are wired PIN 2 HOT.

CIRCUIT DESCRIPTIONS

The following gives a brief description of each module as an aideto understanding the signal flow within the console. Manyreferences are made to the circuit diagrams with the referencenumber for the appropriate diagram being given at the beginningof each module. The master module uses two circuit boardsrequiring four circuit diagrams.

INPUT MODULE (CD1279)

The input module contains eight input channels mounted on acommon set of metalwork. The channels are identical and a consoleis constructed by using 2 or more input modules together with anoutput module and a master module within a frame.

THE INPUT STAGE (CD1279)The same input stage is used for both the microphone and the lineinput. CON2, an XLR style connector, is used for the microphoneinput which is wired to the inner contacts of CON3, the line inputTRS jack. With nothing inserted into the jack socket the signalconnects to the normal contacts and is then fed to an attenuatorwhich is activated by selection of the line input. Resistors R2 andR3 feed phantom power to the microphone input and this is DCblocked from the line input amplifier by C2 and C3. SP1, SP2 andSP6 are filters providing protection from high frequency signalsentering the inputs. Additional filtering is carried out by capacitorsC37, C38, C39 and C40. CON9 (optional) is wired in parallel withthe XLR which allows for wiring the input to a multipole connectormounted on the console frame.

Resistors R7, R8 and R9 form an attenuator when the line input isselected, reducing the input signal by 30dB. C45 and C46 againprovide DC isolation and there is provision at this point for theinsertion of an input balancing transformer. Note that if atransformer is fitted R14 should be changed to 1k. Where atransformer is not fitted two 10R resistors (R10, R11) carry the signalthrough to the input amplifier. D1, D2, D3 and D4 provide clampingfor excessive input voltages and the signal is applied to the basesof transistors Tr5 and Tr7. VR1 is the front panel gain control andthis is connected through the MIC/LINE switch such that in the MICposition the gain range is 20 to 70dB while in the LINE position it is-10 to 20dB.

Signal is taken from the collectors of Trs 5 and 7 and applieddifferentially to the input of IC1A. The output from here is fedback to the emitters of the input transistors through 56k resistorswith one side being phase inverted by IC1B. The phase reverse

15

switch, SW3, selects either the normal or the phase inverted signaland feeds it to the high pass filter stage. This is a three pole highpass filter operating at 80Hz giving a roll off of 18dB per octave.When not required this can be completely bypassed by SW4. Theoutput of SW4 after buffering by IC8B is known as PRE1 and is thepre equaliser signal. PRE1 is a source for the auxiliary sends whichwill be referred to later.

THE EQUALISERThe signal is presented to the equaliser which is a four band design.The high and low frequency sections are built around IC2B withVR7 providing low frequency boost and cut while VR2 provideshigh frequency boost and cut. The middle frequency sections arebuilt around IC3 and use a Wein bridge as the frequencydetermining network. VR3 selects the frequency of operation andVR4 determines the amount of boost or cut given to the hi midsignals while VR5 alters the frequency and VR6 the boost or cut forthe lo mid signals. The output from the equaliser connects to SW5the EQ IN/OUT switch where either the pre equaliser sinal or theequalised signal can be selected to be passed to the insert send.

CON5, a Tip, Ring and Sleeve jack, is used for the insert point withthe Tip being used as the send. SP3 and SP4 are filters preventingnoise from entering the console. The insert return signal is bufferedby IC7A and is then presented to the channel fader. The outputfrom the fader feeds the channel cut circuit.

The pre fader signal feeds the auxiliary cut circuit, the solo buswhen a solo is requested and finally the 3 led signal meter which isdriven from IC6, a quad comparator. There are SIGNAL PRESENT,0dB and PEAK indicators which are powered from a current sourcebuilt around Tr8. The auxiliary cut allows the creation of a PREFADE POST MUTE signal, which can be defeated if required, inaddition to the POST FADE POST MUTE signal.

THE MUTE CIRCUITTr1 is the CHANNEL MUTE fet which is buffered by IC4A andfollowing this the signal is known as POST. This signal routes to thegroups when panning is not used and also feeds the auxiliary sendswhen selected as POST. The pre fade signal goes through a secondAUXILIARY MUTE circuit built around Tr2 to give a PRE FADE POSTMUTE signal called PRE2. LK1 is normally installed allowing thePRE FADE signal to be muted when the channel mute is operated.By removing LK1 and installing LK2 the PRE FADE signal will notmute with operation of the channel mute switch.

16

In order to improve the attenuation of the mute circuits a smallamount of signal is fed forward to cancel with any residual fromthe output of the fets. Resistors R140, R141 and R142 perform thefeed forward for the channel signal while R99, R100 and R101 areused for the auxiliary cut circuit.

The mute circuit can be remotely controlled either through theexternal remote connector or from the four mute groups provided.A SAFE button allows the mute groups to be disabled on themodule. When the local mute button is pressed a ground is placedonto the remote control connector. This can be used to operateexternal equipment such as a midi sequencer or it could beconnected to other channels so that when one channel is mutedothers will also mute. Led 1 indicates a MUTE whether it is local orremote. In every case a MUTE request grounds the base of Tr6causing it to switch off and hence its collector to go high. This isapplied to the gates of Tr1 and Tr2 causing them to switch off sincethey are P channel fets. Tr4 will also turn off causing Tr3 to turn offallowing led 1 to indicate the mute condition.

THE PAN CIRCUITThe POST signal next goes to the pan circuit. This circuit can beswitched between stereo (L/R) and left/centre/right (LCR) modesusing SW15. The output of the pan pot can be routed to the mix orthe groups. If panning to groups is not selected then the groupsreceive the POST signal while, with panning selected, they receivethe output of the pan pot (PANL and PANR). If LCR panning isselected then assigning to mix (SW13) will send signal to the leftcentre and right buses.

If L/R mode is selected no signal will appear on the centre outputexcept by pressing the MONO button (SW27) when the POST signalwill be routed to the centre bus. The groups can only use the leftand right pan pot outputs and therefore if LCR panning is selected,panning to groups will not function in the expected manner.

The pan pot is built around VR16, a dual pot, and IC5. When in L/Rmode only one section of the pot (VR16A) is used and it simplyreduces the resistance to ground of the left or right signaldepending upon the direction of rotation. This reduces theamplitude of the signal on one side while increasing it on the otherto create the panning effect.

When LCR mode is selected the input signal is fed to a centre tapon VR16A. Signal can thus only appear on the left or right outputof this section of the pan circuit (but not both together) with theamplitude depending again on the rotation of the pan pot.

17

The centre output is derived from the same input signal and VR16Bis used to control its amplitude by decreasing the resistance toground when the pot is rotated away from its central position.IC5B buffers the centre signal.

THE AUXILIARY SENDSThe auxiliary sends can use the following three signals :-PRE1, PRE2 and POST.

PRE1 is the pre equaliser signal, PRE2 is the pre fader post mutesignal and POST is the post fader post mute signal.

All auxiliaries will normally receive the POST signal, however, thereare PRE switches associated with the auxiliaries allowing the prefader signal to be selected. The default condition is that PR2 shallbe the pre signal although links allow this to be changed to thePRE1 signal. Only one link of a pair should ever be inserted.

Auxiliaries 4, 5, 6Link 5 PRE1Link 6 PRE2

Auxiliaries 7, 8Link 7 PRE1Link 8 PRE 2

THE SOLO FUNCTIONSW22 is the solo or PFL switch. When operated it places DC ontothe IPCUEDC bus which is detected by the master module. The audiosignal INS_RET is fed onto the IPCUE bus and fed to the monitoringsystem on the master module. If Solo In Place mode is selectedthen the module initiating the solo will have its solo switchdepressed and the incoming SIP signal will have no effect. If themodule did not originate the solo in place the solo switch will notbe depressed and the SIP signal will cause the channel to mute.

THE DIRECT OUTPUTThe direct output is available at CON5, a jack connector. The signalis unbalanced, at a nominal level of 0dBu and by default is thePOST signal. SW28 allows the PRE1 signal to be used.

18

Switches 9, 10, 11, 12, 23, 24, 25 and 26 route the signal to thegroups. Switch 27 routes signal to the MONO (CENTRE) bus andSW13 routes to the stereo MIX bus.

ROUTING AND MUTE GROUPSSwitches 18, 19, 20 and 21 select the mute group buses. They arecombined through diodes D11 through D14 and then go to theSAFE switch SW17 before combining with the local and remoteMUTE signals.

GROUNDINGAll routing to buses is through 10k resistors. All connectors aregrounded to the metalwork (chassis) ground. This is connected to0V by a 100R resistor in parallel with a 10n capacitor. BUSREF istaken from 0V through a 10k resistor.

There is provision for an external meter output on CON8 (option).

THE STEREO INPUT MODULE (CD1302/3)

THE INPUT STAGEThe same input stage is used for both microphone and line inputs.Looking at the left signal path, CON2, an XLR style connector, isused for the microphone input which is wired to the inner contactsof CON3, the line input TRS jack. With nothing inserted into thejack socket the signal connects to the normal contacts and is thenfed to an attenuator which is activated by selection of the lineinput. Resistors R2 and R3 feed phantom power to the microphoneinput and this is DC blocked from the line input amplifier by C2and C3. SP1, SP2 and SP3 are filters providing protection from highfrequency signals entering the inputs. Additional filtering is carriedout by capacitors C37, C38, C39 and C40.

Resistors R7, R8 and R9 form an attenuator when the line input isselected, reducing the input signal by 30dB. C45 and C46 againprovide DC isolation and there is provision at this point for theinsertion of an input balancing transformer. Note that if atransformer is fitted R14 (R214) should be changed to 1k. Where atransformer is not fitted two 10R resistors (R10, R11) carry the signalthrough to the input amplifier. D1, D2, D3 and D4 provide clampingfor excessive input voltages and the signal is applied to the basesof transistors Tr4 and Tr5. VR1A is the front panel gain control andthis is connected through the MIC/LINE switch such that in the MICposition the gain range is 20 to 70dB while in the LINE position it is-10 to 20dB.

Signal is taken from the collectors of Trs 4 and 5 and applieddifferentially to the input of IC1A. The output of IC1A is fed backto the emitters of the input transistors through 27k resistors withone side being phase inverted by IC1B. The phase reverse switchSW28 (located in the left signal path only) selects the normal orphase inverted signal and passes it to the high pass filter formedaround IC2A. This is a three pole high pass filter operating at 80Hzgiving a roll off of 18dB per octave. When not required this can becompletely by-passed by SW3. The output of SW3 passes throughSW19, the MONO R switch to become PRE-L1 which is the preequaliser signal (left). It is a source for the auxiliary sends whichwill be referred to later.

SUMMING AMPLIFIERIC11A sums the left and right signals together to create a monosignal which has its polarity restored by IC11B before beingpresented to switches SW19 and SW20 (the left and right signalcut switches). When Mono R (switch 19) is pressed the left signal iscut and replace by the right signal. Similarly when Mono L (switch20) is pressed the right signal is cut and replaced by the left signal.If both switches are pressed the output of IC11B (a mono signal) isfed to both left and right signal paths.

22

THE EQUALISERPRE1 L1 is presented to the equaliser which is a four band design.The high and low frequency sections are built around IC9A withVR6 providing low frequency boost and cut while VR2 provideshigh frequency boost and cut. The lo middle frequency section isbuilt around IC8/IC202A. VR15 selects the frequency of operationand VR14 determines the amount of boost or cut given to a signal.The hi middle frequncy section is built around IC15B and IC16A.VR17 determines the frequency of operation while VR18 determinesthe amount of boost or cut. The equaliser output feeds the EQ IN/OUT switch, SW29 allowing the pre or post equaliser signal to beselected.

IC7A buffers the equaliser output and feeds it to the fader. Theequaliser output is also used to derive the PFL signal and to drivethe SIGNAL PRESENT, 0dB and PEAK indicators.

THE CUT CIRCUITThe signal path splits at this point to go through two cut circuits.This allows the creation of a PRE FADE POST MUTE signal (whichcan be defeated if required) in addition to the POST FADE POSTMUTE signal. Tr1 is the CHANNEL MUTE fet and the post cut signalis buffered by IC4A. The signal leaving IC4A is the POST FADE signalwhich is then fed through a pan pot that can be routed to thegroups or the L/R mix. The pre fade signal goes through anAUXILIARY MUTE circuit built around Tr2 to give a PRE FADE POSTMUTE signal called PRE2. LK1 is normally installed allowing thePRE FADE signal to be muted when the channel mute is operated.By removing LK1 and installing LK2 the PRE FADE signal will beunaffected by operation of the channel mute switch. IC12A is usedto combine the left and right post fade signals for sending to theauxiliaries. IC12B is used to combine the left and right pre fadesignals for sending to the auxiliaries.

As with the input module a small amount of signal is fed forwardto cancel any residual from the fets to improve the muteat tenuat ion.

THE BALANCE CIRCUITThe post fade signal next goes to the balance circuit. The output ofthe balance pot can be routed to the mix or the groups. The groupsnormally receive the mono post fade signal but with the PAN switchdepressed they will receive the outputs of the balance pot builtaround VR16. By default the balance control works as a pan potwith full attenuation of the unwanted side. A more limited rangeof adjustment can be obtained by changing the circuit as follows :-

23

Move R140 to R141 and R341 to R340 leaving the positions forR140 and R341 blank.

Make R142 and R342 both 10k (they are 0R links).

This will then give a balance range of +3/-6dB.

PEAK AND SIGNAL PRESENT LEDSA PEAK indicator and a SIGNAL PRESENT indicator are driven fromthe post equaliser signal. IC14 is used as a voltage comparator anddirectly drives leds 5 and 6. A reference voltage is applied to pins 5and 7 while audio is applied to pins 3 and 5. The PEAK led comeson 3dB before clipping while the SIGNAL PRESENT led comes onwith a signal level higher than -18dBu.

THE AUXILIARIESWith the exception of auxiliaries 7 and 8 the auxiliaries work inmono using mixed left and right signals which are derived eitherpre or post fade. The following three signals are available :-PRE1, PRE2 and POST.

PRE1 is the pre equaliser signal, PRE2 is the pre fader post cut signaland POST is the post fader post cut signal.

When PRE is selected the PRE2 signal is the factory default setting.Links enable the default settings to be changed.

AUX 1-3Remove link 3 and install link 4 for PRE1.

AUX 4-6Remove link 6 and install link 7 for PRE1.

AUX 7-8Remove link 11 and install link 12 for PRE1.Auxiliaries 7 and 8 may be used as a stereo pair by depressing SW22,the STEREO switch.

24

THE CUT CIRCUIT LOGICSW6 is the mechanically latching CUT switch which when operatedplaces a ground on the cathode of D15 causing the base of Tr3 togo low and therefore the collector to go high. D9 will now stopconducting enabling LED1 to illuminate indicating a cut. Thecollector of Tr3 is applied via R118 and R98 to the gate of Tr1, an Pchannel FET, causing it to stop conducting hence muting the signal.D10 is used to create different on and off switching times for theFET.

As the attenuation of the FET is not perfect a feedforward techniqueis used to cancel any residual signal. A small fraction of the channelsignal is fed to the non inverting input of IC4A where it will sumwith the residual but in anti-phase to it thus cancelling it completely.The operation of the AUXILIARY CUT is similar to that of theCHANNEL CUT. Links 1 and 2 exist to disable the auxiliary cut ifrequired. In this case Link 1 should be removed and Link 2 installed.

An external input and output are available for the CUT function.The external cut output simply extends a ground onto the connectorwhen the cut switch is depressed. The external cut input requiresto ground the cathode of D7 which then has the same effect as thecut switch grounding D6. A simple latching switch contact issufficient.

THE SOLO FUNCTIONSW18 is the solo or PFL switch. When operated it places DC ontothe IPCUEDC bus which is detected by the master module enablingit to replace the selected monitor signal with signal from the solobus (IPCUE). The equaliser outputs are mixed to mono for use asthe solo signal. If Solo In Place mode is selected then the moduleinitiating the solo will have its solo switch depressed and thereturned SIP signal from the master module will have no effect. Ifthe module did not originate the solo in place the solo switch willnot be depressed and the SIP signal will cause the channel to mute.Thus only the module initiating the solo will be left uncut. In thismode no change takes place on the master module and only themodule initiating the solo in place will be heard through themonitoring system.

There is provision for an external meter on connector CON4 (option).

ROUTING AND GROUNDINGAll routing to buses is through 10k resistors. All connectors aregrounded to the metalwork (chassis) ground. This is connected to0V by a 100R resistor in parallel with a 10n capacitor. BUSREF istaken from 0V through a 10k resistor.

THE GROUP OUTPUTS (CD1280/CD1286)

There are two different kinds of output module. Numbers 1 - 6carry a matrix section and auxiliary output while numbers 7 and 8carry a stereo return section and an auxiliary output in addition tothe group output stage.

THE GROUP OUTPUT (CD1286)Links 1, 2, 3, 4, 14, 15, 24 and 25 determine which of the groupbuses will be assigned to the output. Only one link should ever beinstalled. IC7B mixes the bus signals and presents them to IC7Awhich simply phase inverts the signal before feeding the groupinsert point, CON4. This is unbalanced and the send signal is appliedto the tip of the jack. When no plug is inserted the signal isnormalled through the RING contact and sent to the group fader.This is followed by a buffer (IC8A) with 10dB of gain in order thatthe fader can be run with 10dB of gain in hand.

A BUS PEAK indicator is fed from the pre insert signal to givewarning of high signals on the group bus. D5 half wave rectifiesthe audio signal which is then presented to IC11B. This is used as avoltage comparator and drives LED13 when the signal exceeds thevoltage on pin 6 of IC11B. Any signal greater than 3dB belowclipping level will cause an indication.

An AFL feed to the solo system is taken from the output of thefader buffer. It is fed to the OPCUE bus through switch SW9 whichalso applies DC to the OPCUEDC bus.

The group signal goes to the MUTE switch, SW8, from where itsplits off to the meter, the group output, and the sub mix circuitry.

The balanced output stage built around IC10 will simulate atransformer so that it may be used into unbalanced loads withoutany ill effect. Links 7 and 8 are used to bypass the output transformerconnector (CON10) and must be removed if a transformer is used.CON15 may optionally be fitted where the output is to be wired toa multipole connector.

The meter is built around IC12, a BA683A, giving a 12 segmentdisplay with a range of +12dB to -21dB. PR1 is used to calibrate the0dB point while PR2 is used to set the DC offset for the low end ofthe scale. SW1 selects the group or the matrix signal to the meter.Note that the BUS PEAK indicator is also switched between thegroup and the matrix.

CON17 may optionally be fitted to provide signals for a meterbridge.CON17 is switched by SW1 to carry the group or the matrix metersignals.

28

There is a feed to an matrix connector (CON7) and links 5 and 6determine whether the signal is pre or post fade. Link 5 is normallyinstalled giving a POST FADER signal to the matrix. Link 13 is usedto select the matrix bus.

The group can be sub mixed onto the main L/R and centre buses ofthe console. A pan control is required to pan the mono group signalonto the L/R and centre buses and this is constructed around VR15,a dual pot, and IC9. When in L/R mode only one section of the potis used and it simply reduces the resistance to ground of the left orright signal depending upon the direction of rotation. This reducesthe amplitude of the signal on one side while increasing it on theother to create the panning effect. When LCR mode is selected theinput signal is fed to a centre tap on the pot. Signal will thus onlyappear on the left or right output of this section of the pan circuitwith the amplitude depending again on the rotation of the panpot .

The centre output is derived from the same input signal as the leftand right outputs. VR15B is used to control the amplitude of thecentre signal and it is buffered by IC8B. The output of IC8B is fed tothe centre bus of the console when LCR mode is selected and theMIX switch, SW6, is pressed. The POST signal may be fed to thecentre output of the console by pressing SW5 (MONO) which willover ride the centre output of the pan pot in LCR mode.

AUXILIARY MASTER (CD1286)Links 9, 10, 11, 12, 20, 21, 22 and 23 determine which of the auxiliarybuses will be sent to the output. Only one link should ever beinstalled. IC4B mixes the bus signals and presents them to IC4Awhich simply phase inverts the signal before feeding the auxiliaryinsert point CON11. This is unbalanced and the send signal is appliedto the TIP of the jack through SUP11. With no plug inserted thesignal is normalled through the RING contact and sent to theauxiliary master level control, VR1. This is followed by a buffer(IC11A) with 10dB of gain in order that the level control can be runwith 10dB of gain in hand. An AFL feed to the solo system is takenfrom the output of the buffer. It is fed to the OPCUE bus throughswitch SW2 and DC is applied to the OPCUEDC bus.

The buffer output feeds the balanced output stage built aroundIC6. This stage will simulate a transformer so that it may be usedinto unbalanced loads without any ill effect. Links 18 and 19 areused to bypass the output transformer connector (CON2) and mustbe removed if a transformer is used. Components labelled SUP areprovided for the purposes of interference suppression and are fittedto all input and output connections.

29

CON16 may be optionally fitted to feed a meterbridge.

THE MATRIX SECTION (CD1286)A 12 by 6 matrix is formed by output modules 3 through 8. Thegroups account for eight of the inputs with remainder being usedby the left, centre and right mixes and an external input.

CON12, a TRS jack, is used as the external input feeding IC1A whichunbalances the signal and feeds VR2, the level control. The outputof VR2 is combined with the group and mix inputs to the matrix atIC2A with IC2B being used to phase invert the group/mix signalswhich are simply brought in through level control pots VR3-VR10.

The combined signal goes to the matrix insert point, CON3, beforegoing through the matrix output level control, VR14. This is followedby a buffer with 10dB of gain allowing the fader to be used with10dB of gain in hand. The output of the MUTE switch is used tofeed the AFL switch, SW4, in addition to feeding the balancedoutput stage built around IC3.

This stage will simulate a transformer so that it may be used intounbalanced loads without any ill effect. Links 16 and 17 are usedto bypass the output transformer connector (CON9) and must beremoved if a transformer is used. Components labelled SUP areprovided for the purposes of interference suppression and are fittedto all input and output connections.

STEREO INPUT (CD1280)The stereo input is a line level stereo input which can be routed tothe group, auxiliary and mix outputs of the console. Note that if amono input is available then only the left input need be used as itwill be normalled to the right signal path if no jack is inserted intothe right input. IC1 forms the stereo balanced input from wherethe signal goes through a gain control stage using IC2 and VR1followed by the two band equaliser using IC3. The output of theequaliser is summed to mono to create the PRE-M signal used tofeed PFL through SW8 and the auxiliaries. When SW8 is operatedDC is fed onto the IPCUEDC bus to signal the master module that asolo has been requested and audio is placed on the IPCUE bus.

The equaliser is followed by the MUTE switch, SW14, and fromthere the signal goes through a stereo fader. This is followed by abuffer stage with 10dB of gain in order that the fader can workwith 10dB of gain in hand.

30

The post fader stage is presented to a balance control constructedaround VR4 and is mixed to mono to create the POST-M signalused to feed the auxiliaries. The balance control is buffered by IC5giving unity gain with the control in its central position. With thecontrol rotated to the right, for example, the right signal willincrease by 3dB while the left signal will be fully attenuated.

The output of the buffer is fed to the MIX switch, SW2 and thegroup routing switches, SW4 through SW7. The feed to the monobus is through SW3 using the POST-M signal. Auxiliaries 5 through8 can be accessed by the stereo input.

The PRE switch, SW1, allows the auxiliaries to be sent pre fademono signal rather than the post fade mono signal. The STEREOswitch, SW13, allows auxiliaries 7 and 8 to be used as a stereoauxiliary using either the pre or post fade stereo signals.

THE GROUP OUTPUT (CD1280)Links 1 and 2 determine which of the group buses will be assignedto the output. Only one link should ever be installed. IC7B mixesthe bus signals and presents them to IC7A which simply phase invertsthe signal before feeding the group insert point. This is unbalancedand the send signal is applied to the TIP of the jack. When no plugis inserted the signal is normalled through the RING contact andsent to the group fader. This is followed by a buffer with 10dB ofgain in order that the fader can be run with 10dB of gain in hand.A BUS PEAK indicator is fed from the pre insert signal to givewarning of high signals on the group bus. D5 half wave rectifiesthe audio signal which is then presented to IC11B. This is used as avoltage comparator and drives LED18 when the signal exceeds thevoltage on pin 6 of IC11B. Any signal greater than 3dB belowclipping level will cause an indication.

An AFL feed to the solo system is taken from the output of thefader buffer. It is fed to the OPCUE bus through switch SW12 whichalso applies DC to the OPCUEDC bus. The group signal then goes tothe CUT switch SW10 from where it splits off to the meter, thegroup output, and the sub mix circuitry.

The balanced output stage built around IC10 will simulate atransformer so that it may be used into unbalanced loads withoutany ill effect. Links 7 and 8 are used to bypass the output transformerconnector (CON5) and must be removed if a transformer is used.

THE MASTER MODULE

The Master Module supports a number of functions including themain mix outputs, two auxiliary outputs, a tape return input andthe monitoring system. Two circuit boards are used with signalspassing between them when required.

AUXILIARY SENDS (CD1281)Auxiliaries 7 and 8 are located on the master module and theirfunction is identical to the auxiliary masters located on the groupmodules.

Looking at Auxiliary 7 IC1A mixes the auxiliary 7 bus signals andpresents them to IC1B which simply phase inverts the signal beforefeeding the auxiliary insert point. This is unbalanced and the sendsignal is applied to the TIP of the jack. When no plug is inserted thesignal is normalled through the RING contact and sent to theauxiliary master level control, VR1. This is followed by a buffer with10dB of gain in order that the level control can be run with 10dBof gain in hand. An AFL feed to the solo system is taken from theoutput of the buffer. This is fed to the OPCUE bus through switchSW1 and DC is applied to the OPCUEDC bus.

The output of the buffer feeds the balanced output stage builtaround IC3. This stage will simulate a transformer so that it may beused into unbalanced loads without any ill effect. Links 1 and 2 areused to bypass the output transformer connector (CON13) and mustbe removed if a transformer is used.

LEFT, CENTRE AND RIGHT MIX(CD1281/2)IC4A mixes the left bus signals and presents them to IC4B whichsimply phase inverts the signal before feeding the auxiliary insertpoint. This is unbalanced and the send signal is applied to the TIPof the jack. An unbalanced feed to a tape recorder is also takenfrom this point and is suitable for machines operating at -10dBV. Afeed of the CENTRE or MONO mix is also summed with the left andright signals for sending to the tape recorder outputs. When noplug is inserted in the insert jack the signal is normalled throughthe RING contact and sent to the master fader. A BUS PEAK indicatoris fed from the pre insert signal to give warning of high signals onthe master bus. D11 half wave rectifies the audio signal which isthen presented to IC7A used as a voltage comparator to drive LED13.Any signal greater than 3dB below clipping level will cause anindication.

36

The master fader is followed by a buffer with 10dB of gain in orderthat the fader can be run with 10dB of gain in hand. The output ofthe buffer feeds the balanced output stage built around IC8. Thisstage will simulate a transformer so that it may be used intounbalanced loads without any ill effect. Links 3 and 4 are used tobypass the output transformer connector (CON14) and must beremoved if a transformer is used. A feed of the fader buffer outputis also used to feed the centre output of the console when SW8 isdepressed.

The signal paths for the RIGHT and CENTRE signals are identical tothat described for the left signal.

MONITORINGThere are left, centre and right outputs for speakers, a stereoheadphone output and 3 master meters. Solo audio is automaticallyswitched on to the monitor outputs when a solo is active and thereis an external tape input which can be assigned as a monitor sourceor to the left and right outputs of the console.

TAPE PLAY INPUT (CD1283)The external tape input is unbalanced and buffered by IC5 havinga non inverting gain of 5.5dB. The signal passes through CON11(CD1283) to CON10 (CD1282) and from there to the level controlVR2. The inputs to the level control are also taken to the TAPEswitch SW6. The outputs of the level control feed IC13 which has6dB of gain before being presented to switches SW2 and SW3 whichroute it the L/R and MONO outputs of the console. The signals areapplied to the fader buffers and hence the master faders will notaffect the level of the tape signal when assigned to the mix outputsof the console. This means that a tape can be played through theconsole outputs with the main faders closed to suppress other signalsources and is known as an intermission playback facility.

In addition to the TAPE switch the monitor path has a MIX TO MONswitch (SW4) and a CENTRE TO MON switch (SW5). The selectedsource is applied to fets Tr1, Tr2 and T18 which will normally passthe signal. If a solo is active then Tr1, Tr2 and Tr18 will cease toconduct and Tr3, Tr4 and Tr19 will conduct to allow the solo bus tobe fed to the monitor outputs of the console. LMON, RMON andCMON are the signals presented to the monitor outputs.

SOLO LOGIC (CD1282)There are two solo DC buses, IPCUEDC and OPCUEDC which allowinput and output solos to be treated differently.

If an input solo is requested the IPCUEDC bus will go high causingTr7 to turn on and hence its collector to go low.

37

This switches off Tr8 which allows Led 16 to turn on indicating aninput solo. The collector of Tr7 is connected through SW7 (the SIPswitch) to the gate of Tr6, causing Tr6 to switch off.The effect of this is to disable any output solo audio that is active,giving the console input solo priority. The cathode of D7 is nowlow causing Trs 1, 2, 12 and 18 to turn off. Tr11 inverts the outputof Tr7 causing Trs 3, 4, 13 and 19 to turn on.

Thus the normal monitor source is silenced while the solo audio isallowed onto the monitor outputs in addition to the left meternow showing solo audio level instead of the left mix signal. Theoperation of an output solo is very similar other than for the factthat it cannot disable input solos. During a solo the centre andright meters are muted by fets Trs 5 and 6 (CD1283). Solo audio ismixed by IC11B and this is where the solo meter feed is derived.Signal can be adjusted in level by VR3 before going to the monitorsystem without affecting the meter readings.

A Solo In Place mode can also be selected and when this is the casethe output of Tr7 feeds Tr14 causing it to turn on and thereforeTr15 to turn on. This causes a logic low to be placed on the SIP buswhich mutes any input module not having its solo switch depressed.

The master meters are built around BA683A ICs, giving a 12 segmentdisplay with a range of +12dB to -21dB.

Auxiliary 8 and the centre output are as for auxiliary 7 and the leftoutput description previously given.

THE MONITOR OUTPUTS (CD1284)The selected monitor signals LMON, RMON and CMON are fed to avolume control VR4 which is buffered by IC10/11. A PHONES switch(SW14) selects the headphone or loudspeaker outputs. Theloudspeaker outputs are built around IC12, IC13 and IC14 and aresimilar to the balanced outputs used for the main outputs of theconsole. Transformer balancing is not available for the monitoroutputs.

The headphones outputs are designed to feed a low impedanceload and have a transistor output stage. IC17, transistors 1 through4 and associated components form the stereo headphone amplifier.

TALKBACKIC15 is the talkback microphone amplifier with gain beingadjustable by VR3. Link 1 may be installed if a phantom poweredmicrophone is to be used. When the talkback key is pressed Rs 114,115 and 116 connect with the monitor signals to form a DIM circuitof around 15dB.

38

Talkback can be routed to the auxiliaries, the mix or the groups.There are also sine and pink noise generators. They can be switchedon using SW7 and the appropriate source selected by SW6. Therouting for these generators is as for the talkback. VR2 is a levelcontrol for the selected oscillator.

Pink noise is generated from diodes D16 and D17 which aredifferentially applied to IC7A. The output from IC7 is taken throughthe ON switch, SW7, and then applied to IC7B for amplificationbefore filtering by resistors R86—R91 and capacitors C45—C49. Theoutput of the filter is buffered and amplified by IC6B from whereit goes to the SINE/PINK selector switch, SW6.

A 1kHz sine wave is generated by IC16 with D18 and D19 beingused to stabilise the amplitude.

IC16A along with C53, C54 and R97 form a bandpass filterdetermining the frequency of oscillation.

THE BUS LINKING PORT

The bus linking port enables two consoles to be used together in amaster slave configuration. The bus structure is broken betweenthe input modules and the group modules although in normal usea shielded connector is used to join the two sections. If the consoleis to be used as a master the connector is removed and the masterend of a link cable put in its place. This retains the link betweenthe buses and connects the input modules of the slave console tothe buses of the master console. If the console is to be used as aslave the slave end of the link cable is used which breaks the linkbetween the buses and feeds the input modules over to the masterconsole. This of course means that the group and master modulesof the slave console are not used as only one master per functioncan be allowed access to the bus.

During unlinked operation a blanking plug must be inserted toconnect the input and output buses.

CD1308This shows the Bus Link Blanking Plug.

CD1306This shows the Bus Link PCB. There are two input connectors toallow consoles where the master modules are located in the centre.and one output connector. The output and input connectors areconnected by the blanking plug during normal (unlinked)operat ion.

THE METERBRIDGE

VU METERBRIDGE (CD1310)The VU Meterbridge carries 11 meters indicating the three mainconsole outputs in addition to either the matrix, group or auxiliaryoutputs of the console.

Signal selection is carried out by switches SW1 — SW3 while C1ensures that on power up the GROUP signals will be displayed.

IC1 is a dual SR Flip Flop and normally the Reset input will be heldlow by the pull down resitor R3. The Set input is wired to Vss and isthus always low. When SW1 is pressed, or C1 is charging immediatelyafter switch on, Vdd is connected through D1 and R3 to Vss. Currenttherefore flows and a voltage is created across R3 which is enoughtto make the Reset input if IC1a see a logic high. The Q output isthus set to a logic low while the Qbar output will be a logic high. Asimilar situation will arise on IC1b and therefore the A and B controlinputs of the 4052 multiplexers will both be low allowing the X0and Y0 input signals through which are the group signals. IC12aalso reads the control lines. As both are low and the IC is connectedas an invertor the output will go high causing LED1 to illuminate.If neither or only one of the control lines is low the output will notgo high enough to turn on LED1.

If the matrix output is required then SW2 should be pressed. Thiswill cause C2 to charge through R1 creating a +ve pulse on theclock input of IC1A. Assuming that we are in GROUP mode theData input will see the logic high from the Qbar output and thiswill be clocked through to the Q output. The A control line nowgoes high while the B control line stays low causing the multiplexersto allow through the signals on the X1 and Y1 inputs which are thematrix signals.

If the auxiliary outputs are required then SW3 should be pressed.IC1B is clocked by a +ve going pulse from C3. Again the Data inputwhich is high will be clocked through to the Q output causing theB control line to go high. The multiplexers will now allow throughsignals connected to the X3 and Y3 inputs which are the auxiliaryoutput signals. The B control line is connected through to the RESETpin of IC1A and when the auxiliary signal is selected a pulse will becreated through C6 causing IC1A to reset. When the auxiliary signalsare deselected the B control line will go low causing a -ve goingpulse. To prevent this from causing damage to the circuitcomponents it is clamped by D3 and thus prevented from drivingthe reset pin more than 0.6V below ground. C7 and D4 performsimilar functions on IC1B.

44

When the A control line is high the output of IC11b will go lowcausing the MATRIX indicator to illuminate while if the B controlline is high the output of IC12b will go low causing the Auxiliaryindicator to illuminate.

The outputs of the multiplexers are fed through buffer amplifierswith some gain adjustment to allow for calibration of the meters.Resistors attenuate the signal input to the multiplexers when asignal is not selected in order to prevent breakthrough of any highlevel audio signals. The signals for the left, centre and right mixesdo not travel through any multiplexers and are permanentlyselected. There are of course only 6 matrix outputs and meters 7and 8 will therefore not indicate during the period that themeterbridge is being used to indicate MATRIX signals.

LED METERBRIDGE OUTPUT SIGNAL PROCESSING (CD1312)The signal input to the led meterbridge output section is identicalto that of the VU meterbridge. Selection can be made between thegroup, matrix and auxiliary signals. In this case the outputs fromthe multiplexers are fed to quad comparator ICs of the type LM2901.These rectify the audio signals and define the ballistics of theresulting signal that is fed to the display board (CD1311).

LED METERBRIDGE OUTPUT DISPLAY BOARD (CD1311)Each meter is identical and is constructed from 3 quad comparatorICs of the type LM2901 creating a 12 segment meter. A resistorchain is used to set the threshold voltage for each comparator andthis determines the point at which an led will switch on. The ledsare driven from constant current sources formed from transistorsTR1 through TR8.

LED METERBRIDGE INPUT DISPLAY BOARD (CD1307)The meteres are identical to those used on the output display board(CD1311). There is no need for a ballistics and rectifier section inthe meterbridge as the signal is taken from after the ballistics andrectifier section of the meter driver on the module. Further LM2901ICs (IC25 and IC26) are used to buffer the module signals beforebeing presented to the meters.

45

THE POWER SUPPLY

The power supply is a linear type supplying +/-18 volts and +48volts DC to the console. It may be rack mounted and a space of 2Uabove the unit is recommended for ventilation.

The positive and negative rail regulators are identical in operationthus only the positive rail is described.

Diodes D11 through D14 rectify the incoming AC from thetransformer and feed the main reservoir capacitors C9 and C10. Asmall plug in module contains the series pass transistor andassociated regulating circuit. Q002 is the series pass transistor andis driven from Q001 which in turn receives a control signal fromIC001, a 723. The output from the series pass transistor is passeddirectly to the power supply output. D15 indicates that the supplyis functioning.

Diodes D1 through D4 rectify the AC used for the phantom voltagesupply. This is smoothed by C1, C2 and C4 from where it is fed to aTL783C, the regulator. R1, R2 and R4 are used to derive aprogramming voltage which is applied to the TL783C. D5 and D6will protect the regulator from inverse voltages that may be appliedto it. C5 and C15 smooth the regulated output which is applied tothe output connector of the power supply. D7 indicates that thephantom supply is working.

There is a delayed output from the power supply which may beused to activate relays in a console. This facility is not used whenconnected to the CS8 console.

There is no connection within the power supply between 0V andmains earth (chassis). There is a ground lift switch which, whenoperated, will allow the console to float completely free fromground. If the ground is lifted then the console chassis is connectedto 0V Audio in the power supply.

SERVICE INFORMATION

With the exception of the meters there are no adjustments withinthe CS8 console.

SAFETYAlways switch off the console before carrying out any work on it.

TOOLSNo special tools are required in order to service the CS8. Anoscilloscope and multimeter will allow fault finding to componentlevel in the unlikely event of a fault. A module extension cable,ACBL99-023, is supplied with the console to enable individualchannels to be powered when removed from the frame. If acomplete block of 8 channels is to be serviced then ACBL99-024, an8 way extension cable, should be used.

MODULE REMOVALRemove the twelve screws retaining a module and ease it out ofthe frame. There are four screws at the bottom of the module,four screws at the top of the module and four screws at the rear ofthe console at the base of the connector panel. The recommendedmethod is to raise the front of the module and to push the modulea little towards the front of the console from the rear connectorpanel. Lift the module, holding it at the front edge and rearconnector panel. Keep it parallel to the front plane of the consoleand disconnect the ribbon cable from each of the 8 boards beforepulling the module completely clear.

MODULE DISASSEMBLYRemove the screws mounting the XLR to the connector panel.Remove the screws holding the circuit board to the top panel andpull the circuit board clear.

MODULE REASSEMBLYThis is a reverse of the disassembly process and care must be takenthat leds are not damaged through misalignment with their panelholes.

MODULE REPLACEMENTPlace the module over its final position and reconnect the ribboncable to all the boards. Gently ease the module back into the frametaking care not to crush or otherwise damage the ribbon cable.Insert the 12 retaining screws.

STATIC PRECAUTIONSElectronic equipment can be very sensitive to static discharges andcare should be taken to avoid static in the work area. Where possiblework on a bench where you can be grounded through a wrist strap.

59

If boards have to be shipped then they should be wrapped inconductive plastic bags or conductive plastic sheeting.

PARTSIn the interests of safety always use genuine replacement parts.Safety approvals will be invalidated by use of non standardcomponents.

METER ALIGNMENTAn audio test set is required to accurately measure the level of theoutput for which the meter is being adjusted.

Master Left and Right MetersWith 0dBu at the console outputs adjust PR1 to read 0dB and with-21dBu at the console output adjust PR2 such that the bottom ledis just on. These adjustments should be repeated until both readingsare accurate as they are interactive to some extent.

Centre MeterPR15 should be used to set the 0dB point while PR25 should beused to set the -21dB point following the above procedure.

Group MetersPR2 should be used to set the 0dB point while PR3 should be usedto set the -21dB point following the above procedure.

If a meterbridge is fitted then some additional calibration workwill be required as follows:-

VU BridgeCalibrate the console meters as above and then use PR1 throughPR7 to calibrate the VU meters. The adjustment is the same forwhichever signal source is selected and it is therfore probably easiestto set the meters to read GROUP. Set the group outputs to +4dBu(0VU) and adjust PR1 for group 1 so that the meter reads 0VU.Calibrate the remaining meters using PR2 through PR8.

The master meters can be set in the same fashion having set theoutput levels to +4dBu. PR9 will calibrate the left meter while PR10and PR11 will calibrate the centre and right meters respectively.

LED BridgeThere are no adjustments in the led meterbridge.
