C30 preamplifier circuit description. Introduction The C30 pre-amplifier uses pre-amp input switching/control and display boards that are very similar in design to the boards used in both the Diva A85/A90 and Fmj A32 integrated amplifiers and as such you may already be familiar with the layout and topologies of these boards. The C30 boasts a very much over-engineered power supply and output stage that is designed to bring the very best out of the existing Pre-amp input switching board. The main PCB L958AY also contains output buffers for the unbalanced outputs to drive long cables and balanced line drivers. A headphone amplifier is included to drive low impedance headphones down to 32 Ohm. For description of the pre-amplifier switching and control board see the section... Power supply. The mains input comes in via SKT1. Two Y caps return common mode noise to the chassis ground and an X cap reduces any single ended noise. The 1M5 resistor following this is in place to discharge the capacitors when the unit is turned off. The mains selector switch, which follows the resistor, changes the configuration of the transformer windings from series for 230V to parallel for 115V. Tx1 is a standby transformer it powers the microcontroller at all times so that the unit can be put into and out of standby. To reduce voltage losses after this transformer, low forward drop diodes are used. A low drop out regulator follows to create the 4.5v(D) supply; this supply powers the micro and digital circuits. The primary of the Toroid supply transformer Tx2 is connected to CON3 and the power to this is switched on and off by the relay RLY1.

The transformer has a number of secondary outputs and we use separate taps and bridge rectifiers networks followed by bulk capacitors to smooth the ripple. The voltages generated are +24V and -24V for the main analogue supplies, +46V for the HT supply to the VFD, and +18V, which is used to power the trigger output. The smoothed +/- 24V then goes through regulators REG 2 and REG 5 to create +/- 18V this is passed the pre-amplifier PCB via CON4. Another set of regulators REG 3 and REG 6 follow taking the 18V and creating a +/-15V supply that is available for add on modules such as the 7.1 channel input board. A 5v supply is derived via regulator REG 4 from the 18V to run the headphone amplifier. Mains detect. A mains present detector runs from the standby transformer, this detects the loss of mains using a peak hold circuit based around D7/TR1/DZ1 and TR2. If the power is lost this piece of circuitry sends a flag to the microcontroller so it can mute the outputs and shut down the unit. See Fig 1 for notes on protection modes. 12v trigger and RC5 receiver. The trigger output on SKT2 is driven through TR4 to provide a current limited supply at around 13V. IC1 A and B are used to demodulate incoming RC5 from socket SKT2. IC1A is a band-pass filter centred on 36KHz. This is followed by a peak detector circuit that demodulates the incoming signal. Fig 1.

Pre-amp input card. Introduction. The pre-amp stage is a high-performance, DC coupled design with microprocessor control of input select, two independent tape loops, electronic volume control and tone bypass. It features a discrete power supply and low-noise linear circuitry to obtain exceptionally low distortion and noise performance results. Power supply stage The secondary transformer output windings from the main toroid transformer are connected to SK300. The A.C voltage is rectified and smoothed by D300, D301, D306, D307 and C300, C301. The unregulated voltage should be around +/- 27 V obviously this is dependent on the A.C level at the mains inlet socket; F300 and F301 are the secondary A.C s.m fuses these are rated at 2A. The voltage regulators are discrete emitter followers the +15 voltage stage is described below as the �15 v stage is effectively very similar. Q300 and R300 act as a constant current source, supplying around 7mA into D310. C302 and C314 reduce ripple and broadband noise on the zener diode. Q305 and Q306 form a complementary Darlington NPN transistor, which is configured as an emitter follower producing +15v at it�s output. C303 is to provide bulk charge storage and to reduce the AC output impedance of the power supply. D302 prevents reverse bias of the supply during power down. Z301 is a conventional LM317 type circuit to regulate the +15v rail down to +5v for the tone and volume control circuits.

Input switching Each of the inputs has a pair of diodes to the +/- 15v rails to prevent static spikes from causing damage to the CMOS multiplexors. In addition, there is a simple resistor-capacitor filter with a corner frequency of approximately 340kHz to remove any unwanted high frequency interference from the signal. This uses high quality WIMA polypropylene capacitors for the best possible performance. Z104 (left) and Z105 (right) are the main input multiplexers, which are configured in a �virtual earth� unity gain arrangement with Z115 and Z116. This is an inverting circuit topology and the phase is corrected by the inverting volume control. Z115B (left) and Z116B (right) are the integrating servos, which remove any D.C coefficient from the Analogue input switching stages before the signal is passed onto the following stages, R180 and C147 (left) form a filter to remove any broadband noise from the servo output and to improve the speed response. Z100 � Z103 are the Tape output selectors these are non-inverting and the outputs are again buffered by Z9 a/b and Z10 a/b before arriving at the two tape loop outputs. Z106 is configured as a double pole changeover switch and is used to select the tone controls or direct by pass mode. (See below for more information). Tone controls The tone control stage is non-inverting and uses a gyrating bell filter for the Bass and a simple shelving filter for the high frequencies, the left channel only will be described. The input is attenuated by �6dB and biased to a voltage of +2.5v D.C by C111, R113, R112, R110, R111 and C110. This is so the signals fall within the 0 � 5v D.C required by the digital potentiometer Z108.

Z111B and its associated components form an active equivalent of a series resonant LCR circuit. This has an impedance minimum 5.4k at around 80. The digital pots Z108D and Z108A control the bass and treble respectively, this accomplished by moving the wiper connected to the frequency-sensitive impedance between to non inverting and inverting terminals of Z112A, effectively changing the ratio of feedback boost and feed forward attenuation of the circuit at the desired frequencies, thus providing a EQ gain control that is on a logarithmic scale, with the use of a linear pot. Z112B provides the 6dB of gain necessary to bring the nominal level of signal back to unity C116 and C117 remove the 2.5VDC offset from the output to prevent click and bangs when the tone control are activated. Z108 is controlled by a simple 3-wire serial interface from the microprocessor. Each of the digital lines has it�s own ground return these are terminated at the GND pin of the chip to minimize any electromagnetic interference. Volume control Z107 is a VSDVC electronic volume control IC. It works in conjunction with external op-amp Z117a/b by varying the feed-forward and feedback resistors in an inverting gain configuration, the volume control is driven by 3-wire data from the H8 micro on the display board � if the control receives no data it will remain in Audio mute mode. Relay RLY100 shunts the output of the Op-amps to ground at switch on � power down and when switching between inputs.

Audio output stages. The Audio output stage contains the buffered, un-buffered and balanced outputs as well as the headphone driver. The audio signal from the preamp PCB enters the board on CON100 and the direct signal goes straight to the output via the mute relays RlY100A and RLY101B. A buffered version of the signal is created by IC100 and IC101. IC100 and IC101 are op-amps configured as unity gain non-inverting buffers. The C30 also has a Balance XLR output stage that drives into the balanced line drivers IC103 and IC104. These line divers create a transformer-less balanced output. Headphone Output. The selected audio output signal is driven into the headphone driver IC102; this signal then passes through CON101 and CON102 to the headphone socket SKT101. The mute signal passes through the switch contacts in the headphone socket so when headphones are inserted the main outputs are relay muted. Please note: this means that if the headphone sockets control contacts are faulty or damaged the unit will be permanently stuck in audio mute mode. RC5 remote code assignment change. The C30 has the ability to switch between RC5 system code 16* and 19, we can achieve this by pressing and holding the Phono/Aux � CD and AV � DVD buttons simultaneously the display will show. RC5 System Code 16* We can toggle the system code using the rotary encoder.

Display board The display board is very similar in design to the board that has been used for many years in the A85 family of products inc FMJ A32 and as such those of you familiar with these products will know there way around this board, a full description follows. The power supply rails for the display board are derived from the main board we should expect to see the below supplies in place (Fig 2.) Fig 2 Display board power supply pins Power supply Pin number of SK1 + 5v D.C (micro) Pin 14 + 5v D.C Pin 1 + 46v D.C for VFD HT Pin 3

Please note: the H8 micro is very critical of the +5v supply and as such the unit may crash or fail to power up during use if the +5v supply drops below 4.5v. H8 Microprocessor The H8 micro at location Z1 is pre-programmed by Arcam using a flash-programming module and cannot be reprogrammed in the field unless you have access to the appropriate hardware and software. The H8 forms the heart of the C30 and takes on all major control functions including.

1. Control of the input switching. 2. Controls the action of the volume cont. 3. Monitors protection status and mute lines

A85/A90/A32 only. 4. Sends display information to the VFD. 5. Receives and decodes RC5 data. 6. Receives data from rear panel remote

input. 7. Stores setting information via 24C02 E-

prom. At initial power up the H8 micro is reset by Z2 a DS1233 econo reset package. The input switching information is driven out to the Pre-amp card via the 9 select lines that appear on Pins 14 � 22 of SK3.

The Volume control and tone control circuits are driven from the SDATA � SLOAD and SCLK data lines from SK3. The Mute status line has control over the pre-amp output relay at location RLY100; the mute is triggered during power up/down and between input selections and under Mute commands. Within the C30 the DC prot, Therm, VI prot and SP1/SP2 control lines are all connected to Digital ground on the main board of the pre-amp as these are not required within this product. The H8 drives the VFD via 4 Data lines that can be seen on R64 � R67 as DISPDAT, DISPCLK, DISPBLK, DISPLAT these drive directly into the VFD. Remote Data can be received by the C30 via the 3.5 mm Phono jack on the rear of the Pre-amp and the previously described remote demodulator on the main board this demodulated RC5 arrives on the display board via Pin 3 of SK1 and goes into a common IR input pin of the H8 micro (pin 87) this pin is also used to pick the RC5 code up from the Display onboard remote receiver. At power up the H8 reads all previously stored and last settings used by the amplifier from the e-eprom at location IC5 these will include the last input used and tape settings also tone control and input level settings, any changes to the set-up of the amplifier are sent to the e-eprom for future recall, at power down the H8 downloads it�s settings to the e-eprom. All indication LED�s are driven directly from the H8 micro, these LED�s are tagged onto the +5v rail via 10k current limiting resistors Q1 and Q2 form a toggle between Green and Red for the standby/power LED. The volume control is driven from a Rotary encoder at location SW18 the toggle lines from the encoder arrive at the H8 as control lines Phase A and Phase B on Pins 93 and 94.

Multi channel input module (optional) Introduction The multi input module an optional expansion board that allows the existing Amp/Pre-amp to become part of a surround system when driven by a DVD/SACD player with Analogue surround outputs. The board has two sets of 7.1 input (8 channels) these are labelled as MCH1 and MCH2 and accept Left, Right, Centre, Left surround, Right surround, Left Back, Right back audio Information. All input channel levels can be trimmed levels to allow for system balancing. Put very simply this is an eight-channel preamplifier. Power supply The board is powered from the +/- 15v supply on the existing pre-amp board on board regulators REG100 and REG101 regulate these rails down to �5v and +5v respectively. The digital sections of the circuit are powered by a single +5v rail this is isolated from the main 5v rail via inductor L100. Capacitors C100, C101 and C105, C107 act as bulk charge stores to prevent current surges from affecting the main pre-amp stage power supply stages. Micro Processor The micro controller operates from a 4 Mhz crystal and is in control of all of the board�s function via its input/output ports. The micro controller is reset on power up via R/C network R101 and C120. The micro controller stays in reset condition for approximately 500ms this allows the host micro controller (H8 Z1 on display board) to initialize and for the power supplies to settle. The Host micro communicates with the onboard micro via CON 101. Three lines are

used for communication these are seen on the circuit diagram as PB0, receive from ExpBrd and Transmit to ExpBrd. When the host is communicating with the onboard micro controller PB0 will be driven low, otherwise the Data sent will be ignored. Input switching The input allow for the signal routing of the eight channels from either of the inputs these are MCH1 and MCH2, select lines S1-S2-S3 are used to select each bank of inputs this inputs stage utilizes 6 x 74HCT4053 multiplexers you will notice that IC204 and IC205 only utilize the S1 and S2 select channels as this input switch only deals with two channels (Back left and Back right). Please note: The software will only allow one set of inputs to be selected at any one time. The outputs of the input multiplexers drive into a group of 8 line drive Op-Amps (IC300-IC307) these are configured two pole integrating D.C servo before reaching the Volume control stages. Volume control Volume control is performed by two channel Burr-Brown PGA2310 volume control chips. The gain is under micro control with steps of 0.5dB. All volume control chips share Data, Clock and Mute control but have Chip select lines that are grouped in the following way Front Right, Front Left, Centre and Sub share the same select line, and the remaining channels share a chip select line (Surround right and Left, Back right and Left). The volume of each channel can be controlled individually �trimmed�. If a loud clicking is heard on a individual channel whilst adjusting the volume it is probably the input stage that is at fault and not the volume control chip itself, the input stage should prevent D.C levels form entering the volume control.

Page 8: Service Manual C30 Pre-Amplifier

Output driver stage The output driver stage consists of four OPA2134 dual channel Op-Amps (IC400-IC403) each output for instance Front left channel takes one channel of the op-amp. The front left and front right channels are driven down into the Pre-amp board via Pins 1 and 2 of connector Con400 and is fed into the input switches of the Pre-amp boards multiplex on Pin 9 from this point the signal is dealt with as a normal signal input into the Pre-amp. Please note: the left and right signals are seen on the L937 pre-amp card circuit diagrams as module left and module right. The Remaining channels are rail clamped to remove any over-voltage spikes from the rails and to prevent damage to ancillary equipment using diode packages D400 � D405. Each output has a mute relay that when engaged shunts the output to ground at power up and power down preventing any spurious D.C levels from leaving the card. Simplified Block Diagram

Phono stage The Phono board is a simple single stage RIAA amplifier. It consists of two channels of high gain amplification, and switching between moving magnet (MM) and moving coil (MC) settings. PSU: The unit derives its ±15V regulated rails from the unit it is fitted into with only local decoupling capacitors on board. Interface: The unit connects to the host unit via a 8 way connector: Amplifier: The left channel has designators beginning with 100, and the right with 200. For the purposes of this description the left channel will be described, as the right channel the same in all respects. The amplifier is a small signal class A voltage feedback amplifier with switchable gain. The input consists of an actively loaded differential pair of very low noise PNP transistors (TR106, 107). These transistors are very specific and should only be replaced with identical parts with the E grade high gain. TR100 & TR101 form a current source for the pair, which sets the quiescent current for the entire amplifier. The active load consists of TR110 & TR111, which forms part of a differential current mirror with TR112, 113 & 114. This differential stage also has an active load (TR102 & TR103) to keep gain to a maximum. Both of these differential stages are designed to have as much gain as possible to enable the single stage design. The RIAA response is achieved in the feedback network: C101,110,111,112,119,120,&R115,112. C115 is used to correct between MM & MC gains as the amplifier is non-inverting.

SW100 switches between MM & MC. Two poles of the switch change between the different loading required for each type of cartridge: R108 & C109 for MM, and added inparallel for MC R104 & C108. The other two poles change the feedback resistor value to alter the gain. MM: R105 and in parallel for MC R123. The DC offset is controlled by a non-inverting servo built around IC100. The amount of servo current is different for each gain setting via R111 (MM) & R124 (MC) so that the low frequency high pass point remains the same for both settings. However the high pass point for the circuit is set by C113. This gives a warp filter, stops DC startup thumps from upsetting DC coupled circuitry and an approximation of the RIAA/IEC curve (-2dB @ 20Hz). The output is class A buffered by a dual mirror follower (TR104, 105, 108, 109). The quiescent current is set up by D100 and R118, 119. Closed loop stability is achieved with C116, 117 giving symmetrical slewing capability.

Transformer Specification For 115/230V C30 transformer

Arcam Part Number L923TX

Material Safety Specification

1. Winding Wire to be Grade 2 (130C rating) to BS 60317-4 1995

2. Mylar Polyester Insulator 130C Rated

3. Potting Compound PC3502 E135297(M)

Mechanical Specification

1. Middle of transformer to be potted (as shown).

2. Primary windings connect to 6 way MOLEX connector 39-01-2065. Secondary windings connect to 8 way molex connector 39-01-3088. Use MOLEX pin 44476-3112.MOLEX connectors have pin numbers indicated on them.

3. Primary wires are enclosed in a common sleeve. Secondary wires are enclosed in a common sleeve. Use PVC sleeving.

4. All wire lengths in mm. Lengths are +5.0, -0

5. Please adhere rubber insulating pad to bottom of transformer as shown.

Electrical Specification

1. Transformer to have dual 115V primaries to allow parallel operation for 115V input and series operation with 230V input.

2. Transformer input voltage range

115V -18% +14% (97.5V to 132.5V) 230V -18% +14% (195V to 265V)

3. Transformer to have 4 secondary windings as show in the adjacent drawing.

4. Loaded DC voltages specified at 195V AC in (with transformer primaries in series)

5. Each secondary winding to have a full wave (4diode) bridge to produce a single DC rail. (AS shown in diagram)

Output Capacitance is as indicated in table.

The specified voltage figure with this input voltage is to be the minimum voltage on the reservoir capacitor as shown in the diagram.

6. The transformer is intended to be massively overrated so as to provide very low resistance windings for the VP24V7 and VN24V7 supplies.

This will improve the audio quality of the equipment it is to be used in by allowing the flux density to be very low and the wire guage to be larger than would otherwise be the case. The sizes given are maximum finished sizes.

There is no merit in attempting to reduce the size much below the maximum sizes specified. Audio quality will be improved by making the transformer as large as possible.

7. The VP46 and VP18 secondaries are fused by T250mA Fuses. The VP24V7 and VN24V7 secondary windings are unfused.

The transformer must be designed so that a short on either of the unfused windings will cause the primary fuses (2AT) to blow.
