Conforming to this directive will minimise the risk of hearing damage caused by long listening periods. A simple rule to follow is: The longer you listen, the lower the average volume should be. Please take care when working with your audio system – if you are manipulating controls which you don’t understand (which we all do when we are learning), make sure your monitoring level is turned down. Remember that your ears are the most important tool of your trade. Look after them, and they will look after you. Most importantly: Don’t be afraid to experiment to find out how each parameter affects the sound; this will extend your creativity and help you to get the best results.

B General Installation Instructions Please consider besides these general instructions also any product-specific

instructions in the “Installation” chapter of this manual.

B1 Unpacking

Check the equipment for any transport damage. If the unit is mechanically damaged, if liquids have been spilled or if objects have fallen into the unit, it must not be connected to the AC power outlet, or it must be immediately disconnected by unplugging the power cable. Repair must only be performed by trained personnel in accordance with the applicable regulations.

B2 Installation Site

Install the unit in a place where the following conditions are met: • The temperatureand the relativehumidityof theenvironmentmustbe

within the specified limits during operation of the unit. Relevant values are the ones at the air inlets of the unit (refer to Appendix 1).

• Condensationmustbeavoided.Iftheunitisinstalledinalocationwithlargevariationofambienttemperature(e.g.inanOB-van),appropriateprecautions must be taken before and after operation (refer to Appendix 1).

• Unobstructedairflowisessentialforproperoperation.Airventsoftheunit are a functional part of the design and must not be blocked in any way during operation (e.g. by objects placed upon them, placement of the unit on a soft surface, or installation of the unit within a rack or piece of furniture).

• Theunitmustnotbeheatedupbyexternalsourcesofheatradiation(sun-light, spotlights).

B3 Earthing and Power Supply

Earthing of units with mains supply (class I equipment) is performed via theprotectiveearth(PE)conductorintegratedinthemainscable.Unitswithbattery operation (< 60 V, class III equipment) must be earthed separately.

Earthing the unit is one of the measures for protection against electrical shock hazard (dangerous body currents). Hazardous voltage may not only be caused by a defective power supply insulation, but may also be introduced by the connected audio or control cables.

If the unit is installed with one or several external connections, its earthing must be provided during operation as well as while the unit is not operated. If the earthing connection can be interrupted, for example, by unplugging the mains plug of an external power supply unit, an additional, permanent earthing connection must be installed using the provided earth terminal.

Avoid ground loops (hum loops) by keeping the loop surface as small as possible (by consequently guiding the earth conductors in a narrow, parallel way), and reduce the noise current flowing through the loop by inserting an additional impedance (common-mode choke).

V

Installation / EMC

ClassIEquipment(MainsOperation) Should the equipment be delivered without a matching mains cable, the

latter has to be prepared by a trained person using the attached female plug (IEC 320 / C13 or IEC 320 / C19) with respect to the applicable regulations in your country.

BeforeconnectingtheequipmenttotheACpoweroutlet,checkthatthelocalline voltage matches the equipment rating (voltage, frequency) within the ad missible tolerance. The equipment fuses must be rated in accordance with the specifications on the equipment.

Equipment supplied with a 3-pole appliance inlet (protection conforming to class I equip ment) must be connect ed to a 3-pole AC power outlet in such a way that the equipment ca binet is connected to the protective earth.

For information on mains cable strain relief, please refer to Appendix 2.

ClassIIIEquipment(BatteryOperationupto60VDC) Equipment of this protection class must be earthed using the provided earth

terminal if one or more external signals are connected to the unit (see expla-nation at the beginning of this paragraph).

B4 Electromagnetic Compatibility (EMC)

The unit conforms to the protection requirements relevant to electromagnetic phenomena that are listed in guidelines 89/336/EC and FCC, part 15.

• Theelectromagneticinterferencegeneratedbytheunitislimitedinsucha way that other equipment and systems can be operated normally.

• Theunitisadequatelyprotectedagainstelectromagneticinterferencesothat it can operate properly.

The unit has been tested and conforms to the EMC standards of the speci-fied electromagnetic environment, as listed in the following declaration. The limits of these standards ensure protection of the environment and cor-responding noise immunity of the equipment with appropriate probability. However, a professional installation and integration within the system are imperative prerequisites for operation without EMC problems.

For this purpose, the following measures must be followed: • Installtheequipmentinaccordancewiththeoperatinginstructions.Use

the supplied accessories. • Inthesystemandinthevicinitywheretheequipmentisinstalled,useonly

components (systems, equipment) that also fulfill the EMC standards for the given environment.

VI

• Usea systemgroundingconcept that satisfies thesafety requirements(class I equipment must be connected with a protective ground conduc-tor) and that also takes into consideration the EMC require ments. When deciding between radial, surface, or combined grounding, the advantages and disadvantages should be carefully evaluated in each case.

• Useshieldedcableswhereshieldingisspecified.Theconnectionoftheshield to the corresponding connector terminal or housing should have a large surface and be corrosion-proof. Please note that a cable shield con-nected only single-ended can act as a transmitting or receiving antenna within the corresponding frequency range.

• Avoidgroundloopsorreducetheiradverseeffectsbykeepingtheloopsurface as small as possible, and reduce the noise current flowing through the loop by inserting an additional impedance (e.g. common-mode choke).

• Reduceelectrostaticdischarge(ESD)ofpersonsbyinstallinganappropri-ate floor covering (e.g. a carpet with permanent electrostatic filaments) and by keeping the relative humidity above 30%. Further measures (e.g. con-ducting floor) are usually unnecessary and only effective if used together with corresponding personal equipment.

• Whenusingequipmentwithtouch-sensitiveoperatorcontrols,pleasetakecare that the surrounding building structure allows for sufficient capacitive coupling of the operator. This coupling can be improved by an additional, conducting surface in the operator’s area, connected to the equipment housing (e.g. metal foil underneath the floor covering, carpet with conduc-tive backing).

C Maintenance All air vents and openings for operating elements (faders, rotary knobs) must

be checked on a regular basis, and cleaned in case of dust accumulation. For cleaning, a soft paint-brush or a vacuum cleaner is recommended.

Cleaning the surfaces of the unit is performed with a soft, dry cloth or a soft brush.

Persistent contamination can be treated with a cloth that is slightly humidified with a mild cleaning solution, such as dishwashing detergent.

For cleaning display windows, commercially available computer/TV screen cleanersaresuited.Useonlyaslightlydamp(neverwet)cloth.

Never use any solvents for cleaning the exterior of the unit! Liquids must never be sprayed or poured on directly!

For equipment-specific maintenance information please refer to the corre-sponding chapter in the operating and service manuals.

D Electrostatic Discharge during Maintenance and Repair

Caution: Observetheprecautionsforhandlingdevicessensitivetoelectrostaticdischarge!

Many semiconductor components are sensitive to electrostatic discharge (ESD). The lifespan of assemblies contain ing such components can be dras-tically reduced by improper handling during maintenance and repair. Please observe the following rules when handling ESD sensitive components:

• ESDsensitivecomponentsshouldonlybestoredandtransportedinthepacking material specifically provided for this purpose.

ESD / Repair

• Whenperformingarepairbyreplacingcompleteassemblies,theremovedassembly must be sent back to the supplier in the same packing material in which the replacement assembly was shipped. If this should not be the case, any claim for a possible refund will be null and void.

• UnpackedESDsensitivecomponents shouldonlybehandled inESDprotected areas (EPA, e.g. area for field service, repair or service bench) and only be touched by persons wearing a wristlet connected to the ground potential of the repair or service bench by a series resistor. The equipment to be repaired or serviced as well as all tools and electrically semi-conducting work, storage, and floor mats should also be connected to this ground potential.

• TheterminalsofESDsensitivecomponentsmustnotcomeinuncontrolledcontact with electro statically chargeable or metallic surfaces (voltage puncture, discharge shock hazard).

• Topreventthecomponentsfromundefinedtransientstressandpossibledamage due to inadmissible voltages or compensation currents, electrical connections should only be established or separated when the equipment is switched off and after any capacitor charges have decayed.

Appendix 1: Air Temperature and HumidityGeneral

Normal operation of the unit or system is warranted under the ambient condi-tions defined by EN 60721-3-3, set IE32, value 3K3.

This standard consists of an extensive catalogue of parameters, the most important of which are: ambient temperature +5...+40 °C, relative humidity 5...85% (i.e., no formation of condensation or ice); absolute humidity 1...25 g/m³; rate of temperature change < 0.5 °C/min. These parameters are dealt with in the following paragraphs.

Undertheseconditionstheunitorsystemstartsandworkswithoutanyprob-lem.Beyondthesespecifications,possibleproblemsaredescribedbelow.

Ambient Temperature

UnitsandsystemsbyStuderaregenerallydesignedforanambienttempera-ture range (i.e. temperature of the incoming air) of +5 °C to +40 °C. When rack mounting the units, the intended air flow and herewith adequate cooling must be provided. The following facts must be considered:

• Theadmissibleambienttemperaturerangeforoperationofthesemicon-ductor components is 0 °C to +70 °C (commercial temperature range for operation).

• Theairflowthroughtheinstallationmustprovidethattheoutgoingairisalways cooler than 70 °C.

• Averageheatincreaseofthecoolingairshallbeabout20K,allowingforanadditionalmaximum10Kincreaseatthehotcomponents.

• Inordertodissipate1kWwiththisadmissibleaverageheatincrease,anair flow of 2.65 m³/min is required.

Example: A rack dissipating P = 800 W requires an air flow of 0.8 * 2.65 m³/min which corresponds to 2.12 m³/min.

• Ifthecoolingfunctionoftheinstallationmustbemonitored(e.g.forfanfailure or illumination with spot lamps), the outgoing air temperature must be measured directly above the modules at several places within the rack. The trigger temperature of the sensors should be 65 °C to 70 °C.

Frost and Dew

The unsealed system parts (connector areas and semiconductor pins) allow for a minute formation of ice or frost. However, formation of dew visible to the naked eye will already lead to malfunctions. In practice, reliable opera-tion can be expected in a temperature range above –15 °C, if the following general rule is considered for putting the cold system into operation:

If the air within the system is cooled down, the relative humidity rises. If it reaches 100%, condensation will arise, usually in the boundary layer between the air and a cooler surface, together with formation of ice or dew at sensi-tive areas of the system (contacts, IC pins, etc.). Once internal condensation occurs, trouble-free operation cannot be guaranteed, independent of tempera-ture.

Beforeputtingintooperation,thesystemmustbecheckedforinternalfor-mation of condensation or ice. Only with a minute formation of ice, direct

Appendix

XI

evaporation (sublimation) may be expected; otherwise the system must be heated and dried while switched off.

A system without visible internal formation of ice or condensation should be heated up with its own heat dissipation, as homogeneously (and subsequently as slow) as possible; the ambient temperature should then always be lower than the one of the outgoing air.

If it is absolutely necessary to operate the cold system immediately within warm ambient air, this air must be dehydrated. In such a case, the absolute humidity must be so low that the relative humidity, related to the coldest system surface, always remains below 100%.

Ensure that the enclosed air is as dry as possible when powering off (i.e. before switching off in winter, aerate the room with cold, dry air, and remove humid objects such as clothes from the room).

These relationships are visible from the following climatogram. For a con-trolled procedure, thermometer and hygrometer as well as a thermometer within the system will be required.

Example1: AnOB-vanhavinganinternaltemperatureof+20 °C and a relative humidity of 40% is switched off in the evening. If the temperature falls below +5 °C, the relative humidity will rise to 100% (7 g/m³); dew or ice will be forming.

Example2: AnOB-vanisheatedupinthemorningwithairof+20 °C and a relative humidity of 40%. On all parts being cooler than +5 °C, dew or ice will be forming.

D23m System

2 INTrOdUCTION Featuring an enhanced channel count architecture that allows customers of

Vista X and Vista V digital consoles to transfer huge number of channels, the D23m I/O system works seamlessly with Infinity Core and A-Link inter-face technology. Because the D23m is fully compatible with D21m systems already in the field, all existing D21m I/O-cards are fully compatible and can be used in the D23m frame, protecting existing customer investments.

The D23m I/O system provides very cost-effective inputs and outputs with maximum flexibility while maintaining the well-known Studer sound quality. It is the first Studer I/O system ready to handle 192 kHz operation. Different I/O modules can be plugged into a frame, providing I/O systems tailor-made to customer needs. And all this comes with an unequalled form factor. Full redundancy is available starting from power supplies going up to redundant interconnections.

2.1 System Philosophy The audio between the mixing console or router system and the D23m con-

nects via the A-Link interface.

When using the D23m I/O system the Infinity core itself does not provide I/O, but is connected to the D23m frame (acting as a hub) by using the ‘A-Link’ technology. Since A-Link uses optical fibre, the distance from the core to the hub frame is not a topic, as it can be several kilometers. From the D23m hub-frame it is possible to run optical fibre MADI links to multiple D21m remote I/O boxes. A maximum of 24 remote I/O boxes (stage boxes) may be connected to one D23m frame by using six D23m Quad Madi I/O cards. Should more I/O channels be required then multiples of the ‘local frames’ (hubs) may be used within the system.

A-Link

To the Infinity core, a maximum of eleven D23m frames can be connected. Redundancy issues are regarded as highly important. It is therefore possible to run A-Link connections with redundant cables to a redundant Infinity core or a D23m with redundant cable connection to a single core (cable redundancy), which reduces the total number of D23m to five per Infinity core. From the D23m hub frame to the remote stage boxes, also MADI links can have


D23m System

redundant cables. The system is automatically switching to the redundant MADI connection in case the primary connection should fail. For 96 kHz operation the second MADI link can be used as a channel count extension, transferring a total of 64 MADI channels even at a 96 kHz sampling rate. For the redundancy behaviour of the A-Link interface please refer to chapter 2.6.

The MADI link between the D23m hub frame and the D21m remote I/O boxes, in addition, carries all control signals needed to control the microphone amplifier cards, to interrogate the state (health) of any remote I/O card and to display it within the console’s system surveyor page. This is without sac-rificing any audio channels within the MADI link. Additionally, an RS422 signal can be ‘tunneled’ through the MADI connection. In this way e.g. a MIDI device can be connected to the remote I/O box and find the ‘extension’ connector on the D23m hub frame again.

Notes The D23m I/O system cannot be used as a standalone system, D23m frames need to be connected to an Infinity core or a SCoreLive in order become functional.

With D21m frames however, two I/O boxes can be interconnected using MADI, where one of them must be switched to ‘Master’ mode. In such a case up to 64 audio channels may be transmitted between two frames (applicable for MADI HD cards A949.0411.23, A949.0413.22, A949.0414.20, or newer).

The D23m frame has the same dimensions as the D21m frame. With a height of 3 U, the frame provides 12 slots for I/O card insertion. I/O cards can either be of the new D23m I/O card type (with large I/O numbers), or D21m I/O cards as they are already used with D21m I/O systems and remote frames.

Each I/O card may provide a different number of I/O channels, depending on


D23m System

its channel count (e.g. a microphone card provides four channels of micro-phone inputs, while an ADAT card provides 16 channels of inputs and outputs simultaneously). Some cards are mechanically occupying two slots, and therefore a maximum of 6 double-width cards may be inserted into a frame. An overview of the different cards currently available is given in chapter 5.1.

The D23m frame hosts one A-Link card in the middle of the frame, providing the main audio connection to the DSP core. From the A-Link card the signals are redirected to the different types of I/O cards in the frame.

D23m offers some DSP processing power provided by signal processor on the A-Link card. This allows processing for all necessary patching and signal routing directly on the A-Link card.

In the slot on the left side to the A-Link card, always an Ethernet card must be installed. This card hosts an ethernet switch with four ports available on the front of the card. Also the Reconfig button can be found on the Ethernet card.

The D23m frame may also be equipped with redundant power supplies, the status of which can be displayed in the Vista console’s system surveyor page.

Please note that the rack mounting brackets may be installed either on the front (as shown on the opposite page) or on the rear of the frame.

2.3 How to use the d23m Frame The D23m frame normally acts as a hub frame. This means that it is carrying

local I/O as well as MADI links to remote stage boxes. Since the A-Link is optical and therefore also large distances can be covered

from core to D23m frame, it is also possible to use the D23m frame for remote I/O. With such remote D23m frames it is possible to carry large channel numbers (up to 1536 inputs and outputs).

D21m- and D23m frames have identical dimensions

2.4 How to use the d21m Frame Within a D23m I/O system, the D21m frame can only be used as a remote

I/O frame. The D21m frame then carries a MADI HD Link card, which con-nects to the D23m hub frame and allows a channel number of 64 inputs and outputs to be used.

As written above, also D23m frames can be remote I/O frames - but when 64 input and output channels are sufficient for the remote frame, the D21m would be the more cost efficient solution.

Frame dimensions are the same as shown in chapter 2.3 above.

2.5 Clocking concept of the d23m system with Infinity core The Sync signal of the D23m system is etiher internally generated by one

of the D23m frames, or an external sync signal is connected to one of the D23m frames. The sync signal is then transmitted to the core via A-Link. All other frames will be synced from the core via their audio interface (MADI or A-Link).

The D23m system is able to connect to external sync sources to be synchro-nised. Following sync sources can be used:

•Video •WordClock •AES/EBU •A-Link(mainorredundant) For Video 50 Hz, 59.94 Hz, and 60 Hz are supported. For all other sync sources

48 kHz, 96 kHz, 192 kHz, 44.1 kHz, 88.2 kHz, and 176.4 kHz are supported.

An automatic process is employed to ‘look’ for the best possible sync source.


D23m System

This process has the following rules :

1. External Clocks have higher priorities then internal clocks. 2. The priorities of the external sync signals are in this order : 1. Video reference, 2. Word clock, 3. AES/EBU 4. A-Link 3. The lowest A-Link portnumber (on the core) has the highest priority. 4. Once a switchover to a different sync source has occured, the system

will automatically switch back to the original source, as soon as this sync signal is restored.

If the D23m system consists of multiple frames and a redundant Infinity core

system, the above process provides an audio clock redundancy. If the D23m frame which is the sync source, fails, the system will switch over to the next possible D23m frame that can be the sync master.

2.6 redundancy The D23m I/O system offers an optimum of redundancy including full PSU

redundancy, with easily replaceable power supplies.

The D23m host card (A-Link HD card) offers two A-Link ports, main and redundant with automatic switching - the D23m frame switches automatically to the redundant connection, in case the main connection fails.

A-Link Quality of Service Every A-Link carries its Qualtiy of Service indication, which is depending on the state of the source that generates the A-Link signal.

Looking at this QoS, the D23m system can decide to switch from the main A-Link to the redundant A-Link signal.

QoS is taking into account the following criterias of the source that generates the A-Link signal :

•Isthecorecurrentlycontrolled(e.g.byadesk)?Orhasitnocontrol? •AreallSFPequippedA-Linkportsactive? •Aredropoutsoccuringintheaudioprocessing?

If at least one of these criterias is not met, the QoS of the A-Link signal gets reduced. Each D23m frame then switches to the A-Link port (main or redun-dant) with the better QoS value.

‘Main preferred’ Once a switchover has occured, and the problem situation is resolved - which means that all QoS values are restored to the maximum - the D23m system immediately switches back to the main A-Link signal.

The redundancy concept of the D23m I/O system closely interacts with the redundancy of the connected DSP core :

Redundancy with SCoreLive The SCoreLive A-Link DSP card also features main and redundant A-Link ports. If both ports are equipped with a SFP and connected to a D23m frame - cable redundancy is provided. If the main cable connection fails, the D23m frame automatically switches to the redundant port without any loss of audio.

For OnAir 3000 systems with SCoreLive and A-Link DSP cards, there are a number of parameters that can be specified in the configuration tool.


D23m System

These parameters are ‘Combine mode’ and ‘Force Mode Alink’ port. They allow to control the redundancy behaviour in an OnAir system. For details please refer to the OnAir 3000 Operating Intructions, chapter 6.

This is so far unique to the OnAir application.

Redundancy with Infinity Core With the Infinity core, the customer can decide the level of redundancy.

If core redundancy is desired, two Infinity cores have to be deployed : should an audio dropout occur within the main core, the QoS of the A-Link signal is reduced and therefore the D23m frame switches to the redundant port where the redundant core is connected. In this case, also the active core would be switched from main to the redundant.

If A-Link cable redundancy is desired with a single core - this is possible with SW V5.3.06 and higher. It requires the Infinity core to be switched to the “Redundant Version” Gateware configuration. In this mode, the Infinity core can handle upt to five D23m frames with redundant A-Link cables.

If within a system, only local I/O is needed, one or multiple D23m frames can be used. With the D23m I/O system, even local I/O frames can be further away from the core than 10 metres. Since SFP modules are utilised for the A-Links, optical connections of various formats are possible and can cover very long distances.

D23m Frame with MADI I/Ocards to connect to the RemoteFrame

In most cases, remote I/O frames carry microphone inputs. If a D23m frame

is filled with microphone input cards, 12 cards can be placed in one frame as a maximum. This results in a channel count of 48 microphne inputs.

Since the same 48 microphone inputs also find place in a D21m frame, it is more cost efficient to chose D21m remote frames, if only a small channel


D23m System

count is required in the remote frame (<= 64 inputs and 64 outputs). Such a D21m remote frame must then be linked to a D23m hub frame via

MADI. The D23m hub frame connects to the core via A-Link. Notes The channel count of the MADI link may be set in steps of eight channels

using card-internal DIP switches. In order to provide synchronization and surveyor information it is necessary to provide a MADI link to and from the D21m remote frames at all times, even if the channel count should be set to 0.

3.3 One remote I/O Box with large channel count Only when a larger channel count is needed (> 64 inputs and outputs) it is

necessary to chose a D23m frame as a remote I/O frame.

This example shows three Vista X with a router and two Vista 1. All Vistas

and the router are connected to the Mediornet ring. The studio I/O is a typical D23m system with D21m as remote stageboxes that is directly connected to the Mediornet via four A-Link connections. The Vista1’s are connected to the Mediornet via MADI.

All Vistas and the router can get access to all the studio I/O.

Please note that synchronisation between the consoles and the router and the Mediornet is not part of the diagram.

In the above example, three Vista X with redundant Infinity cores are shown. All three Vistas are connected to a Route 3000 with SCoreLive. The SCore-Live is therefore equipped with three A-Link DSP cards where all the redun-dant Infinity cores are attached via A-Link. As local- and remote I/O to the router, D21m frames are deployed.

4.3 router with Mediornet

This example shows four Vistas with SCoreLive and A-Link DSP cards which are connected to a Mediornet unit which acts as a router. Via this router, the I/O of the attached D23m frames can be accessed from every Vista. Please note that with the routing capabilities of Mediornet, not only entire D23m frames can be routed to a Vista, but individual inputs and outputs of different frames at a granularity of one single input or output.

5.1 Mapping of I/O Cards to MadI and Hd link Channels For Information about mapping D21m I/O card channels to MADI-HD and

HD-Link channels, please consult the D21m Operating Instructions manual.

5.2 96 kHz OperationD23m Frame The A-Link is capable of handling 768 channels (inputs and outputs) at 96

kHz (resp.88.4 kHz).

Infinity Core Whether the system runs at 48 kHz or 96 kHz is depending on the loaded VMC-Config. A VMC-Config is specifically made for one single sampling frequency.

5.3 192 kHz Operation The D23m I/O system and the Infinity series DSP cores are capable of operat-

ing at 192kHz. Currently there are no I/O cards which support this sampling rate.


D23m System

5.4 Input/Output delays The processing delays of the SCoreLive are slightly different from the pro-

cessing delays of the Infinity series cores. The charts below show the resulting effective signal delays from Input to Output for the two different core types, with any possible I/O configuration.

Note Enabled input and output SRCs each cause an additional delay, depending on input and output sampling rates – for details refer to chapter 5.4.1, below.

Digital interfaces such as MADI, ADAT, and TDIF interfaces have approxi-mately the same delay as the AES/EBU interface (±1-2 samples).

5.4.1 additional SrC delay

Enabled input and output SRCs each cause an additional delay (D) depending on the input and output sampling rates (fS_IN and fS_OUT).

Input and output delays can be calculated using the following formulas:

[2] fS_OUT > fS_IN : D = 48

fS_IN[s][1] fS_IN > fS_OUT : D = 16

fS_IN+ [s]32

fS_OUT

Examples For a 96 kHz input signal and a 48 kHz system clock (i.e., the input SRC’s output), the input delay is 40 output samples or 833 µs (formula [1]).

For a 48 kHz system clock (i.e., the output SRC’s input) and a 96 kHz output signal, the output delay is 96 output samples or 1 ms (formula [2]).

** Double-width cards must be inserted into odd slot numbers (e.g. slots 1, 3, 5…).*** For each MADI link, the number of channels transmitted to and from a card may be defined in steps of 8 channels by using DIP switches on the card. **** Regardless of the number of channels defined with the DIP switches, each MADI link can be set to the standard 56-channel MADI mode or the extended

64-channel MADI mode. Therefore a link may have to be set to ‘56 channel’ mode in order to operate correctly with legacy MADI devices. In this case the number of channels set internally for this link should not exceed 56.

6.3 Hd Cards 6.3.1 a-link Hd Card ( ) 5037063

The D23m A-Link HD card provides the link to the DSP core systems. Each input and output can handle up to 1536 channels @48kHz.

The card detects all other I/O cards that are inserted into the D23m frame and displays their presence on the front panel of the card. Once all audio interface cards are plugged in, pressing the Reconfig key on the front panel of the Ethnernet card confirms the configuration to the system. Then all cards are activated and their audio signals are fed into the A-Link.

The A-Link HD card also offers some DSP processing power. This allows processing for all necessary patching and signal routing directly on the A-Link HD card.

SFP modules are used for the front panel A-Link interfaces, these hot plug-gable devices are available in a variety of optical and electrical formats. As a standard, optical multi mode SFPs are used.

6.4 Control data Cards6.4.1 Ethernet Card ( ) 5042095

The Ethernet card is used to establish a control data link between the back-plane of the D23m frame and the control system, e.g. a Vista desk. This can be achieved by using Cat5 cable between the frame and the desk. From Vista SW V 5.2 and upwards, it is possible to tunnel the Ethernet control link data into the A-Link, going to the Infinity core. The Infinity core then needs to be networked to the control desk - this is done by using an Cat5-SFP on the last A-Link port of the Infinity core, where an Ethernet cable is fed to the Vista desk.

The Ethernet card also hosts the Reconfig switch. This switch only needs to be pressed when new I/O cards are inserted into the D23m frame, or when the channel count has been adapted on one or several of the already used cards. When pressing the switch, all I/O cards are scanned and audio signal paths are linked to the A-Link.

6.5 Power Supply and Miscellaneous6.5.1 Power Supply 5037379-01

The D23m I/O frame may be equipped with either one or, for redundancy purposes, with two power supply units.

The module used is a primary switching AC/DC converter with an input volt-age range of 90-264 VAC/50-60 Hz, automatic power factor correction and a standard IEC mains inlet.

It contains no adjustable elements; if the internal primary fuse should fail, the unit must be returned to the factory for repair.

The power supply unit also contains the electronics that generate the second-ary voltages - therefore full power redundancy is provided when using two power supplies.

FAN/STATUS Connector This front-panel connector (15-pin D-type f) is used to output an electri-cally isolated status signal when the primary power supply (or one of them) should fail. The contacts of a relay are available on this connector, as well as a +24 VDC supply and ground. The relay is energized as long as all supply voltages are ok, pins 4 and 6 are connected then. In case of failure of any of the frame’s supply voltages, pins 6 and 8 are connected. The connector in addition allows supplying a fan unit (A949.0597); for the 15-pin connector on the current version A949.0404 a 1:1 m/f cable (C089.201167) is used.

Please note that only the connector of the right-hand PSU can be used for the status and supply signals, even if two power supply units are installed in the D23m I/O frame.

6.5.2 air deflector/Filter Unit A949.0599

If a D23m I/O frame has a power dissipation of less than 80 W, air deflector/filter units should be used on top of and below the frame. For frames dissipat-ing more power, an air deflector/filter unit should be used on top of the frame, combined with a fan unit (see below) at its bottom. If space is available, a second air deflector/filter unit may be used below the fan unit, increasing the air intake cross-section and thus improving the cooling efficiency.

For more information on cooling and guidelines for power dissipation estima-tion refer to chapter 1.2.2, paragraph ‘thermal considerations’.

6.5.3 Fan Unit A949.0597

In cases where the power dissipation of a D23m I/O frame exceeds 80 W, active cooling is imperative. If no cooling system for the whole rack is used, this 1U fan unit is required underneath the D23m frame. The fans draw air in from the front (filtered) and from the bottom (unfiltered) and blow it out upward. The bottom is open and allows installing an additional air deflector/filter unit underneath the fan unit as described above, increasing the air intake cross-section. In most cases, however, closing the fan unit’s bottom with a piece of metal sheet is sufficient.

For power supply to the fans and fan status monitoring, two connectors are provided, one at the front, the second at the rear of the unit. They are con-nected in parallel so that either one can be used, depending on the applica-tion. If any of the fans should have a short or open circuit, the alarm signal is triggered.

A 15-pin D-type cable (order no. C089.201167) for connection to the primary PSU is required.

Please note that currently the fan monitoring is implemented for the use of the fan unit within an SCore Live only.

For more information on cooling as well as guidelines for power dissipation estimation refer to chapter 1.2.2, paragraph ‘thermal considerations’.
