LASER PRODUCT

A1 First Aid

Assemblies or sub-assemblies of this product can contain opto-electronic devices. As long as these devices comply with Class I of laser or LED products according to EN 60825-1:1994, they will not be expressly marked on the product. If a special design should be covered by a higher class of this standard, the device concerned will be marked directly on the assembly or sub-assembly in accordance with the above standard.

In Case of Electric Shock: Separate the person as quickly as possible from the electric power

source:

• By switching off the equipment,

• By unplugging or disconnecting the mains cable, or

• By pushing the person away from the power source, using dry, insulating material (such as wood or plastic).

• After having suffered an electric shock, always consult a doctor.

Warning! Do not touch the person or his clothing before the power is turned

off, otherwise you stand the risk of suffering an electric shock as well!

If the Person is Unconscious: • Lay the person down

• Turn him to one side

• Check the pulse

• Reanimate the person if respiration is poor

• Call for a doctor immediately.

(sunlight, spot lights).

Earthing of units with mains supply (class I equipment) is performed via

the protective earth (PE) conductor integrated in the mains cable. Units with battery 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).

ESD/Repair

Class I Equipment (Mains Operation)

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 (IEC320/C13 or IEC320/C19) with respect to the applicable regulations in your country.

Before connecting the equipment to the AC power outlet, check that the

local line voltage matches the equipment rating (voltage, frequency) within the admissible 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 equipment) must be connected to a 3-pole AC power outlet so that the equipment cabinet is connected to the protective earth.

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

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 explanation at the beginning of this paragraph).

B4 Electromagnetic Compatibility (EMC)

The unit conforms to the protection requirements relevant to electromag-

netic phenomena that are listed in guidelines 89/336/EC and FCC, part 15.

• The electromagnetic interference generated by the unit is limited in such a way that other equipment and systems can be operated normally.

• The unit is adequately protected against electromagnetic interference so that 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 corresponding 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:

• Install the equipment in accordance with the operating instructions. Use the supplied accessories.

• In the system and in the vicinity where the equipment is installed, use only components (systems, equipment) that also fulfill the EMC standards for the given environment.

• Use a system grounding concept that satisfies the safety requirements (class I equipment must be connected with a protective ground conduc-

III

Installation/Maintenance/ESD

tor) and that also takes into consideration the EMC requirements. When deciding between radial, surface, or combined grounding, the advantages and disadvantages should be carefully evaluated in each case.

• Use shielded cables where shielding is specified. The connection of the shield to the corresponding connector terminal or housing should have a large surface and be corrosion-proof. Please note that a cable shield connected only single-ended can act as a transmitting or receiving antenna within the corresponding frequency range.

• Avoid ground loops or reduce their adverse effects by keeping the loop surface as small as possible, and reduce the noise current flowing through the loop by inserting an additional impedance (e.g. commonmode choke).

• Reduce electrostatic discharge (ESD) of persons by installing an appropriate floor covering (e.g. a carpet with permanent electrostatic filaments) and by keeping the relative humidity above 30%. Further measures (e.g. conducting floor) are usually unnecessary and only effective if used together with corresponding personal equipment.

• When using equipment with touch-sensitive operator controls, please take care 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 conductive 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 humidi-

fied with a mild cleaning solution (soap-suds).

For cleaning display windows, commercially available computer/TV

screen cleaners are suited. Use only a slightly damp (never wet) 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 Instructions manuals.

D Electrostatic Discharge during Maintenance and Repair

Caution: Observe the precautions for handling devices sensitive to electrostatic dis-

charge!

Many semiconductor components are sensitive to electrostatic discharge

(ESD). The life-span of assemblies containing such components can be drastically reduced by improper handling during maintenance and repair work. Please observe the following rules when handling ESD sensitive components:

• ESD sensitive components should only be stored and transported in the packing material specifically provided for this purpose.

• When performing a repair by replacing complete assemblies, the removed assembly must be sent back to the supplier in the same packing

IV

ESD/Repair

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.

• Unpacked ESD sensitive components should only be handled in ESD protected areas (EPA, e.g. area for field service, repair or service bench) and only be touched by persons who wear a wristlet that is 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.

• The terminals of ESD sensitive components must not come in uncontrolled contact with electrostatically chargeable (voltage puncture) or metallic surfaces (discharge shock hazard).

• To prevent undefined transient stress of the components and possible damage 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.

E Repair

Removal of housing parts, shields, etc. exposes energized parts. For this

reason the following precautions must be observed:

• Maintenance may only be performed by trained personnel in accordance with the applicable regulations.

• The equipment must be switched off and disconnected from the AC power outlet before any housing parts are removed.

• Even if the equipment is disconnected from the power outlet, parts with hazardous charges (e.g. capacitors, picture tubes) must not be touched until they have been properly discharged. Do not touch hot components (power semiconductors, heat sinks, etc.) before they have cooled off.

• If maintenance is performed on a unit that is opened and switched on, no un-insulated circuit components and metallic semiconductor housings must be touched, neither with your bare hands nor with un-insulated tools.

Certain components pose additional hazards:

• Explosion hazard from lithium batteries, electrolytic capacitors and power semiconductors (watch the component’s polarity. Do not short battery terminals. Replace batteries only by the same type).

• Implosion hazard from evacuated display units.

• Radiation hazard from laser units (non-ionizing), picture tubes (ioniz- ing).

• Caustic effect of display units (LCD) and components containing liquid electrolyte.

Such components should only be handled by trained personnel who are

properly protected (e.g. safety goggles, gloves).

Appendix

Appendix 1: Air Temperature and Humidity

General

Normal operation of the unit or system is warranted under the following

ambient conditions 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.

Under these conditions the unit or system starts and works without any

problem. Beyond these specifications, possible problems are described in

failure 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 to 70 °C.

The unsealed system parts (connector areas and semiconductor pins) allow

for a minute formation of ice or frost. However, formation of dew visible with the naked eye will already lead to malfunctions. In practice, reliable operation 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 sensitive areas of the system (contacts, IC pins, etc.). Once internal condensation occurs, trouble-free operation cannot be guaranteed, independent of temperature.

Before putting into operation, the system must be checked for internal for-

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

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 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.

Example 1: An OB-van having an internal temperature of 20 °C and relative humidity

of 40% is switched off in the evening. If temperature falls below +5 °C, dew or ice will be forming.

Example 2: An OB-van is heated up in the morning with air of 20 °C and a relative

humidity of 40%. On all parts being cooler than +5 °C, dew or ice will be forming.

Appendix 2: Mains Connector Strain Relief

For anchoring connectors without a mechanical lock (e.g. IEC mains con-

nectors), we recommend the following arrangement:

Procedure: The cable clamp shipped with your unit is auto-adhesive. For mounting

please follow the rules below:

• The surface to be adhered to must be clean, dry, and free from grease, oil, or other contaminants. Recommended application temperature range is +20...+40 °C.

• Remove the plastic protective backing from the rear side of the clamp and apply it firmly to the surface at the desired position. Allow as much time as possible for curing. The bond continues to develop for as long as 24 hours.

• For improved stability, the clamp should be fixed with a screw. For this purpose, a self-tapping screw and an M4 bolt and nut are included.

• Place the cable into the clamp as shown in the illustration above and firmly press down the internal top cover until the cable is fixed.

D21m System

maximum ﬂ exibility while maintaining the well-known Studer sound quality. It is the ﬁ rst Studer I/O system providing full 96 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 and DSP cards.

Note: The examples in this document use the SCore. Although most applications

refer to this usage, the majority is also valid for use with the Performa core.

2.1 System Philosophy

When using the D21m I/O system the DSP core itself does not provide I/O,

but is connected to the ﬁ rst D21m frame within the system (acting as a hub) by using Studer proprietary “HD Link” technology. On the DSP core side, the connection is made to the DSP card(s) directly. Link distance is limited to 10 m, so the ﬁ rst I/O box should be located close to the DSP core. From that frame it is possible to run optical-ﬁ ber MADI links to multiple places, up to several kilometers away. By using this “star” architecture it is ensured that a possible problem with one of the remote I/O boxes will not lead to a general breakdown of the whole I/O system. A maximum of six remote I/O boxes (stage boxes) may be connected to one hub frame. Should more I/O channels be required then multiples of the “local frames” (hubs) may be used within the system.

Redundancy issues are regarded as highly important. It is therefore possible

to run any MADI links with redundant cables. The system is automatically switching to the redundant connection in case the primary connection should fail. For 96 kHz operation the second link can be used as a channel count extension, transferring a total of 64 MADI channels even at 96 kHz sampling frequency. The “redundant” MADI link may also be used for sharing an I/O box between two consoles.

The MADI link between the ﬁ rst D21m frame (hub) and the remote I/O boxes,

in addition, carries all control signals needed to control the microphone ampliﬁ er 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 sacriﬁ cing

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 ﬁ nd the “extension” connector on the hub frame next to the core again.

Notes: Unlike the Studer D19m I/O system, the D21m system is engineered as an

I/O system for use together with a Studer digital console, i.e., using the D21m system as a “standalone” analog-to-digital or digital-to-analog converter only works if MADI I/O is used on the digital side; for more information on this subject please Line input card and getting the A/D-converted signal out of the AES/EBU card directly is not possible. This can be done only if the audio is routed with a DSP core. Since the MADI signal to the D21m remote I/O box is used to synchronize the unit, a stable, low-jitter MADI signal is necessary in order to reach maximum audio quality. This is guaranteed by Studer equipment.

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

1.949.411.23, 1.949.413.22, 1.949.414.20, or newer).

Power Supply

The 3 U frame provides 12 slots for I/O card insertion. Each card may provide

a different number of I/O channels, depending on its capabilities (e.g. a microphone card provides four channels of microphone 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 doublewidth cards may be inserted into a frame. An overview of the dif ferent cards currently available is given in chapter 6.1.

The frame hosts one or two “High Density Link” cards (short: HD Link),

providing the main audio connection to the DSP core. From the HD card(s) the signals are redirected to the different types of I/O cards in the frame. Therefore at least one HD card must be inserted in the frame.

The frame may 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.

D21m System

2.3 Hub Frame

The difference between a D21m frame acting as a hub or as a remote I/O

box is the type of HD Link and RS422 cards inserted. The HD Link card in the hub frame hosts four RJ45 connectors for connection to the DSP core, providing 192 channels (96 in case of the Performa core) of audio coming from the DSP core through 2 cables into the frame (audio outputs), as well as 192 channels from the frame through 2 cables into the DSP core (audio inputs). The length of the high-density link cables must not exceed 10 meters (30 feet).

If multiple remote I/O boxes are connected to one hub frame, more channels

need to be transferred to the DSP core. In this case it is possible to insert a second HD card into the hub frame, expanding its capabilities to handle 384 inputs and outputs to the DSP core (192 outputs in case of the Performa core).

2.4 Remote I/O Frame

The frame placed remotely is equipped with a special MADI HD card. This

version of the card is not equipped with the Studer proprietary high-density link but with standard MADI optical interfaces. This format allows transferring 64 channels of inputs and outputs between the remote I/O box and the hub frame simultaneously.

Frame dimensions are the same as shown in 2.3 above.

If the hardware found at startup time is not identical to what the system expects, the user is asked whether the expectations should permanently be changed or whether the user has temporarily changed the I/O conﬁ guration (such as having moved a remote I/O box to another place for the current production). In both cases the surveyor application indicates “green”, unless the user tells it to wait for the missing I/O components.

There is no need to tell the system which channel has a microphone preampli-

ﬁ er included, since this detection is done automatically. However , it is necessary to deﬁ ne which HD link of the hub frame is going to which PED21m card within the Performa DSP core. This is done in a software menu accessible for system administrators only.

The channel count of the MADI link may be set in steps of eight channels

The protocol switch on the front panel of the MADI I/O card may be set to

“64 channel” to allow maximum usage of the available channels. This switch may only have to be set to “56 channel” protocol for operation with thirdparty MADI devices (in case no remote I/O box is connected to the MADI I/O card).

If 64 channels of MADI transmission are required when working at 96 kHz,

the redundant MADI line can be used as a “channel extension” for transmitting the MADI channels 33-64 (29-56). This must be set accordingly with a DIP switch on the MADI I/O card inserted in the hub frame.

It is possible to connect one remote I/O box to two hubs or consoles at the

same time. This allows sharing of one box between two consoles. While the audio inputs are fed to both consoles, the outputs on that I/O box may only be fed by one of the two consoles at a time. An input selector switch on the MADI HD card determines from which console the audio outputs are fed. At the same time only the currently selected console will be able to display health information in the surveyor. If the switch is set to “redundant”, the remote I/O box jumps freely onto the second input in case the signal is lost on the main input. Unless the signal is interrupted on the redundant input, too, the system will not switch back to the main input in order to avoid undeﬁ ned switching in case of a bad MADI connection.

Notes: Some of the I/O cards are “double-width”, of which a maximum of 6 may be

ﬁ tted in one D21m frame. When only using single-width cards, a maximum of 12 can be ﬁ tted. Therefore, e.g. a maximum of 48 microphone inputs may be ﬁ tted in one (full) frame. If outputs are required as well, up to 44 microphone inputs are possible since then at least one slot is used for an 8-channel line output card.

Input and Output cards may be inserted in any order. The system is ﬁ lling

up the MADI channels automatically, starting from the leftmost card subsequently to the right.

Since the MADI bandwidth can only be adjusted in steps of 8 channels, an

odd number of microphone cards (providing 4 inputs each) will result in 4 MADI channels without audio.

The MADI HD card versions 1.949.411.21/1.949.413.21 and newer support

operation with two MADI HD cards in one frame, extending the total channel count between the hub frame and the remote I/O box to 128. The same channel count is reached in 96 kHz mode. For details please

5 ADDITIONAL INFORMATION

5.1 Mapping of I/O Cards to MADI and HD Link Channels

The HD card is redirecting the audio channels from the different I/O cards

into the Studer proprietary HD link format (in case of a hub) or MADI (in case of a remote I/O box). In order to design a complete I/O system, it is mandatory to know which channels of the I/O cards end up being redirected to which one of e.g. the 64 MADI channels. This will inﬂ uence the way the conﬁ guration editor software is used and the labels are selected when starting the operation of a new system.

General rule: The HD card ﬁ lls in all channels starting from the left side of

the frame (slot 1) to the right. Input and output cards may therefore be mixed, but their order dictates the “ﬁ lling up” of MADI outputs from the frame. In the same way the order of outputs from left to right is deﬁ ning which MADI inputs are being redirected to that card. The same rule applies for the Studer proprietary HD link format.

The following example illustrates the rules within a complex I/O system:

5.2 Special Case: Microphone/Line Input Card

The smallest modularity of channels used up within the MADI and Core link

is eight. If an odd number of Mic/Line input cards is used, they should be inserted in pairs, with the last card in an odd slot (no. 1, 3, 5...) This single card will allocate 8 channels but only 4 of them will have audio. If a Mic/Line input card pair uses Analog Insert cards, they should be placed in the next double slot on the right, as shown in chapter 5.3.

For clearness, see the following examples:

Example 1:

10 Mic/Line Input cards (40 channels) 1...40

2 Line Input cards (16 channels) 41...56

Example 2:

9 Mic/Line Input cards (36 channels) 1...36 (37...40 no audio)

2 Line Input cards (16 channels) 41...56

Example 3:

9 Mic/Line Input cards (36 channels) 1...36 (37...40 no audio)

3 Line Input cards (24 channels) 41...64

Input Cards MADI Channel Usage

5.3 Analog Insert Cards

If you plan to equip the I/O box with Analog Insert cards, it is wise to avoid

channels without signal by installing two Mic/Line Input cards next to each other, followed by two Analog Insert cards to their right. The Analog Insert cards will be connected to “their” Mic/Line Input card by a ribbon cable. After that, more Mic/Line Input cards may be inserted. This way all channels within the hub-to-core link will be carrying audio, since there is always a group of 8 channels inserted next to each other. The two Analog Insert cards will not use any channels within the link. The ribbon cables are lead through slots provided in both the Mic/Line Input and Analog Insert cards.

D21m System

5.4 96 kHz Operation

D21m Frame: The D21m I/O system is fully supporting 96 kHz operation. For digital for-

mats, the following standards are supported:

AES/EBU 2 channels are sent over one cable, both at 48 kHz and 96 kHz, just by dou-

bling the clock frequency of the transmitted signal in 96 kHz operation.

MADI 0...64 channels are transmitted at 48 kHz (depending on the DIP switch set-

tings), and 0...32 channels are transmitted at 96 kHz. In the latter mode, the clock frequency is doubled to 96 kHz, similar to the AES/EBU format. In order to reach 64 channels of transmission between remote I/O boxes and the hub frame at 96 kHz, the card’s redundant MADI connections can be selected to transmit the “lost” half of the ﬁ rst cable. This is done by a DIP switch on both the MADI I/O and the MADI HD cards.

ADAT At 96 kHz, only 8 channels are transmitted (4 per optical interface). TDIF At 96 kHz, only 8 channels are transmitted. MADI HD If more than 32 channels are required in 96 kHz mode, the AUX interface

must be used as a “channel extension” to the main interface (i.e., DIP switch #1 is OFF); it will then transmit channels 33...64 of the 96 kHz MADI signal. Subsequently , MADI connection redundancy will not be available in 96 kHz mode when exceeding a total channel count of 32 into or out of the remote I/O box.

Performa Core: • For 96 kHz operation, the DSP core must only contain PE and PED21m cards

and a MemNet card type 1.950.621.xx (not 1.950.620.xx) or newer.

• In addition, the Performa core must contain a “Revision A” backplane.

• An external, high-quality (low-jitter) 96 kHz sync signal in AES/EBU format

must be provided.

• The session conﬁ guration has to be re-calculated. Some I/O channels may

then have no audio but will still show up in the patch window . This is due to the fact that some I/O cards (e.g. ADAT) will provide only half the number of audio channels at 96 kHz.

5.6 The MADI Interface: 64 or 56 Channels?

The D21m I/O system is fully supporting the MADI protocol of 56 channels

(standard MADI) as well as 64 channels (not supported by all third-party MADI devices). Protocol selection is done on the front panel switch of the MADI I/O card. Between a D21m hub and a D21m remote I/O box always 64-channel format should be selected, since the MADI HD card in the remote I/O box expects the 64 channel protocol.

Note: The protocol switch on the front panel of the MADI I/O card is not related to

the channel count setting by the DIP switch on the card itself. In other words, you possibly only use 32 MADI channels (determined by DIP switch), but you nevertheless have to select whether the standard MADI protocol (“56 channels”) or the extended version is used. The correct setting of the protocol switch on the front panel is purely depending on the third-party equipment connected to that MADI interface.

D21m System

5.7 Standalone D21m I/O System

Previously only available for Studer digital mixing consoles, the D21m I/O

system is now opened up for use with any audio equipment. With the introduction of the D21m remote control software, the microphone amps and A/D converters become available to a wide range of applications, such as recording, broadcast, and live sound.

A D21m I/O frame can be connected to any 3rd-party device using its optical

MADI interface. The remote control software runs on a PC, connected to the I/O frame over an additional RS422 serial connection. This software may even rut at the same time as DAW software.

The I/O frame itself is highly modular, and it is possible to select from a

variety of I/O cards. Thanks to the two MADI interfaces the D21m I/O keeps its channel count high even in 96 kHz mode. This makes this product ideal for any use with a Digital Audio Workstation (DAW). In 48 kHz mode the second MADI interface interface serves as a digital split output for feeding any additional audio device or as a redundant audio link.

In facilities containing Studer Vista consoles, the investment is broadened by

the extreme versatility of the D21m stage boxes. One day they can be used on stage, connected to the Studer console, and the next day in the recording studio in order to bring superb audio quality to lower-cost recording equipment.

Remote Software The control software is an application running under Microsoft Windows

XP on any regular PC with an RS422 serial port. The software automatically detects the connected hardware and allows controlling the microphone ampliﬁ er’s parameters, such as phantom power , high-pass ﬁ lter, soft clipping, analog insert, gain, labeling and color coding the inputs, and stereo linking two subsequent channels.

These parameters may be stored and recalled using snapshot ﬁ les. Spare

inputs may be hidden from the screen, while the used ones can be arranged in any order. Operating speed is maximized by the ability to group inputs in a Vista-like way (“ganging”).

MADI Interface The MADI IF of the D21m frame supports both the standard MADI protocol

with up to 56 audio channels as well as the extended protocol with 64 channels. Protocols are selected on the front panel of the frame.

D21m System

The frame acts as a clock slave and synchronizes to the optical MADI signal.

It therefore automatically detects the clock rate of the connected audio device. Supported clock rates are 44.1, 48, 88.2, and 96 kHz.

In 44.1 and 48 kHz mode the two MADI interfaces work in parallel. One of

them may be used as a digital split output or for redundancy . In 88.2 or 96 kHz mode the MADI IF only transmits a maximum of 32 channels. Therefore the second MADI IF is used to bring back the original total channel count.

D21m System

5.8 Connection to the Performa Core

The Performa core is connected to the D21m I/O System in a similar way as

the SCore. The main difference is that the HD link connection from the core towards the D21m I/O frame only carries up to 48 channels (at both 48 and 96 kHz). In order to implement a correct mapping of the I/O cards’ channels to the HD Link, the “Performa Mode” switch (or jumper) must be ON on the HD cards. In the Performa core, use of the PE-D21m card (1.950.606.22) is mandatory . Each card implements one HD link input with up to 96 channels, and one HD link output with up to 48 channels.

Application Examples: Local I/O Only (located close to the core)

** Double-width cards must be inserted into odd slot numbers (e.g. slots 1, 3, 5…). *** The number of channels transmitted to and from a card may be deﬁ ned in steps of 8 channels by using DIP switches on the card. **** Regardless of the number of channels deﬁ ned with the DIP switches, a switch on the front panel switches the MADI protocol between the standard 56-

channel format and the extended 64-channel format. Therefore this switch may have to be set to “56 channel” protocol in order to operate correctly with third-party MADI devices. In this case the number of channels set internally should not exceed 56.

Important! If wired correctly, the microphones are isolated from the D21m chassis. The

circuit inside the microphone takes its supply from pins 2 and 3 (+ and –) for the positive, and from pin 1 (GND) for the negative reference. If a patch bay is implemented, GND (pin 1 on XLR connector) of each microphone input must be connected to its corresponding GND pin, but not to the chassis. If chassis instead of GND is used as negative reference for a microphone, it can occur that the GND net of the D21m is pulled towards –48 V. This causes the HD link receivers not to work correctly or to be damaged, depending on the type and number of microphones connected.

As a workaround, GND and chassis may be connected inside the D21m frame.

In cases where currents ﬂ ow between the chassis nets of multiple devices, the analog signals can degrade in quality (e.g. perceivable as hum).

6.3 Digital I/O Cards

6.3.1 AES/EBU I/O Cards ( and ) 1.949.422, 1.949.423, 1.949.424

AES/EBU input/output card with 16 Ch I/O. With input and output SFCs

(1.949.424), with input SFCs only (1.949.423), or without SFCs (1.949.422 – not available for OnAir 3000). Selectable output sampling frequencies: 96 kHz, 48 kHz, 44.1 kHz, or external reference (22...108 kHz). Input SFCs can be bypassed individually. Output SFCs can be bypassed in groups of four. Output dither is selectable for every AES/EBU output from 24 bit, 20 bit, 18 bit or 16 bit. Settings are made with jumpers. Inputs and outputs on standard 25-pin D-type connectors (female).

SFC Delay: Enabled input and output SFCs each cause a delay (D) that depends on the

SFC’s input and output sampling frequency (f delays can be calculated using the formulas below.

Examples:

• For a 48 kHz system clock (i.e., the “input signal” of the output SFC) and a 96 kHz output signal, the output delay is 96 output samples or 1 ms (formula “2”).

Please note that for a word length reduction the output SFCs must be set to

Enabled; if so, the output word length is always 21 bit maximum. Whenever an SFC is enabled, the three least signiﬁ cant bits (LSB) are set to digital zer o. This results in the speciﬁ ed dynamic range of 120 dB.

Input SFC (1.949.423 and 1.949.424 only) Enabling or bypassing of the SFCs for indi-

vidual AES/EBU input channels.

Output Sampling frequency (1.949.424 only) The output sampling frequency may be set for the AES/

EBU output channel groups 1...4 and 5...8; selection from 44.1 kHz, 48 kHz, 96 kHz, or synchronized by the signal at the AES EXT SYNC IN connector (see “Note” above).

If no valid signal is provided at the AES EXT SYNC IN connector but Ext.

is selected, the output sampling frequency will be set to the system clock. Outputs set to Ext. can therefore be used in a very ﬂ exible way: Connect no external sync signal, if not necessary , so that the output will be clocked with the internal system clock. As soon as an external sync signal is provided to the AES EXT SYNC IN connector, the output will be clocked with the ext. sync signal.

Output SFC / WL Reduction (1.949.424 only) Enabling/bypassing of the output SFCs, separate for the

AES/EBU output channel groups 1...4 and 5...8. Please note that for word length reduction the output SFCs must be set to Enabled.

6.3.2 MADI I/O Cards ( and ) 1.949.430, 1.949.431, 1.949.433

The MADI I/O card can establish a 64-channel MADI input and output to the

D21m frame, are provided on SC connectors available in multi-mode and single-mode versions, as well as a ver

additional word clock output on a BNC socket.

The auxiliary interface can be used as a redundant link or, in 96 kHz opera-

tion, to extend the number of channels from 32 back to 64.

It is possible to transmit any serial control signals, such as MIDI or Sony 9-

pin (machine control) through a MADI connection without losing any audio bandwidth or microphone control of the remote I/O box. For this purpose, an RS422 connector is located on this card (hub frame side). The desired baud rate can be set with a rotary switch. The pinout of the RS422 connector can be set to “device” or “controller” with a DIP switch, depending on the 3rd party serial device connected.

The sync transfer direction (from master to slave) is set using the DIP switches S1 and S4.7/.8. Please note that in such a case the twisted-pair wiring has to

be done with a crossover cable. On the slave core, the WCLK output must be patched to the WCLK input of the audio clock card.

6.3.5 SDI Input Card ( and ) 1.949.441

The HD/SD SDI (serial digital interface) 16-channel de-embedder card is able

to de-embed eight or 16 audio channels from SDI-SD as well as from SDIHD video streams. For the D21m I/O system it acts as an eight-or 16-channel audio input card. These two modes are determined by hardware switches located on the card.

The SDI standard deﬁ nes up to 16 audio channels transmitted within a video

signal. These 16 channels are divided into four groups of four each. The user can determine by hardware switches whether all four groups, or only groups 1+2, or only groups 3+4 will be de-embedded.

The card hosts SFCs (sampling frequency converters) that are bypassed per

default. When bypassed, the SDI card is fully compatible to receiving embedded Dolby from the SDI stream is not in sync with the local system. This means that the mixing console can run fully independent of the video sync used for SDI.

This card works at a sampling frequency of 48 kHz only.

6.3.6 SDI I/O Card ( and ) 1.949.442

The HD/SD SDI (serial digital interface) embedder/de-embedder card is able

to handle video signals according to the SD as well as the HD standard. It can act as an eight-channel embedder, an eight-channel de-embedder, or as a combination of the two. Therefore, for the D21m I/O system it may act as an eight-channel audio input card, an eight-channel audio output card, or an eight-channel input and output card. These three modes are determined by hardware switches located on the card.

The SDI standard deﬁ nes up to 16 audio channels transmitted within a video

signal. These 16 channels are divided into four groups of four channels each. The user can select which two groups are to be embedded or de-embedded by hardware switches on the card: either groups 1&2, or groups 3&4. It is also possible to clear the SDI data structure possibly present in the incoming video signal and to allocate the groups from scratch.

The D21m SDI card hosts sampling frequency converters for both the audio

inputs (de-embedding) and outputs (embedding). So the mixing console can run independent of the video sync used for SDI. The sampling frequency converters can be bypassed. When bypassed, the SDI card is fully compatible to transmitting the Dolby is hardware-bypassed to output A.

This card works at a sampling frequency of 48 kHz only.

About Dolby

®

E/Digital Decoder Card ( and ) 1.949.443/.444

®

E Dolby® E allows encoding of up to 8 mono audio channels and some metadata

into a pair of two channels (e.g. AES/EBU) by using 20 audio bits thereof. Both encoding and decoding processes create one video frame of delay. Since the encoded data is packaged in sizes of one video frame it is possible to “edit” the encoded stream, as long as the edits are synchronized with the video frames and the stream is not modiﬁ ed in any way (e.g. level changes applied).

tion given below is valid independently for both decoders as well. The dualdecoder card receives four AES/EBU pairs the front panel input, or eight mono channels from the console-internal patch (showing up as patch destinations). Each pair may contain a Dolby E or Dolby Digital encoded signal. The card returns a total of max. 16 channels to the console patch (showing up as patch sources).

The single-decoder card returns up to eight channels to the console patch

(eight sources) and shows eight inputs on the patch. Input channels 5...8 are unused.

While it is possible to manually select individual inputs both from the front

panel connectors as well as from the console-internal patch, the card hosts an automatic source selection mode where the inputs are chosen automatically according to the following priorities:

• Whenever a valid AES/EBU signal is detected (“locked” status) on the 15pin front panel connector, this input has priority over the console-internal patch sources. Hence if it is requested to feed the decoder with a consoleinternal signal selected via the patch window, no valid AES/EBU input signal is allowed on the front panel connector.

• However, if no valid AES/EBU signal is detected on the front panel inputs, the card is getting its inputs from the console-internal patch. These inputs are referred to as “Rear/Backplane Inputs”. Selection is as follows:

®

- Input 1, 2: Main priority input for Dolby

E signal, decoder 1.

- Input 3, 4: Backplane input of decoder 1; is automatically selected in

®

case no Dolby

E signal is present on main input (1, 2). Please note that a Dolby® E signal can be fed into this input, too, and it will be decoded correctly. However, if a Dolby

®

E signal is detected on the main input,

this will be taken with higher priority.

OFF

Decoding a Dolby® E stream always causes a delay of one video frame. In

case a regular PCM signal is fed to the card, this can be delayed by one video frame, too. If required, this delay may be de-activated in order to pass through a PCM signal with a minimal delay. The front panel VIDEO IN sync input is used to detect video frames in order to delay the PCM signal accordingly. The video sync input doesn’t necessarily have to be connected in case of

Metadata and Downmixing: A Dolby® E stream contains metadata with

out from the front panel connector. The D21m Dolby

E decoder card only uses this information in case a 2-channel stereo downmix is required from a 5.1-channel surround signal within the Dolby® E stream; then the decoder interprets the center and surround channel levels and uses them for the internal downmixer that is activated by the DIP switches S1.7 and S1.8. The downmix can be made constantly available and, subsequently, overwriting any audio data that was contained on these channels beforehand (“forced downmix”), or it is possible to “ﬁ ll” the channels 7/8 or 15/16 only if the metadata indicate that these channels are not being used otherwise (automatic downmix).

Possible Pitfalls with Dolby® E In order to transmit or record a Dolby® E encoded signal, the whole signal path

must be 100% transparent, regarding the 20 audio bits contained within the

data stream. In case of problems with decoding the Dolby® E signal and possibly getting white noise instead of the decoded signal, the whole signal path should be checked. It may be worthwhile verifying the following points:

• Are there any sampling frequency converters (e.g. when using the D21m

®

Dolby

E decoder card together with the D21m SDI card) in the signal chain? If so, they must be bypassed; otherwise the Dolby® E stream is modiﬁ ed and cannot be decoded anymore.

• In case the signal is sourced from a video tape machine: Is the machine set up to be transparent for the recorded audio signals? Several machines require seting the tracks to “DATA” mode in order to guarantee unity gain while recording or playing back Dolby® E streams.

• Is the card receiving the Dolby® E stream from the console-internal patch? If so, are both tracks patched to the correct two inputs of the card? (Decoder 1 main: channels 1 and 2; decoder 1 PCM: channels 3 and 4; decoder 2 main: channels 5 and 6; decoder 2 PCM: channels 7 and 8).

• If getting a wrong signal or no signal at all: Are any AES/EBU signals present at the front panel while console-internal streams should be decoded? If the card is in “automatic source selection” mode, the front inputs have

®

top priority, regardless whether a Dolby

E stream is recognized or not.

6.3.10 EtherSound® Card ( and ) (details: www.digigram.com)

The EtherSound

®

Sound

network. Towards the D21m system, it acts similar to a MADI card

®

card allows connecting the D21m I/O System to an Ether-

combined with a GPIO card. The number of audio channels used can be conﬁ gured with DIP switches. The included, virtual GPIO card allows, e.g., routing a GPO of the mixing console to the GPO of a distant EtherSound device on the network. Conﬁ guration of the EtherSound

®

network is per-

®

formed either through the ETH CTRL connector or from a remote location on

®

the EtherSound

The EtherSound

networks or with EtherSound

network, e.g. using the EtherSound® EScontrol software.

®

card works with EtherSound® ES-Giga System Transport

®

ES-100 Audio Transport networks. The operating mode of the card (ES-100 or ES-Giga) is selected by setting jumper J22 (see opposite page). The selected mode will be displayed on the front panel LEDs.

®

The audio clock of the EtherSound

network must be synchronous with the

D21m I/O system’s audio clock. This is ensured either by using the Ether-

®

Sound device that is actually the EtherSound

card as clock source of the EtherSound® network, or by feeding the

®

network clock source with a word

clock synchronous with the D21m I/O system’s audio clock.

This card works at sampling frequencies of 44.1 or 48 kHz (88.2/96 kHz

ready).

6.5 HD Cards

6.5.1 HD Card S ( ) 1.949.412

The D21m HD card S provides the link to the DSP core systems. Each input

and output can handle up to 96 channels in each supported sampling frequency (in combination with the Performa core, the number of I/O channels is restricted to 48). The system clock used is taken from the host DSP system, so no extra synchronization is needed.

The card detects all other I/O cards that are inserted into the D21m system

and displays their presence on the front panel of the frame. Once all audio interface cards are plugged in, pressing the RECONFIG key on the front panel conﬁ rms the conﬁ guration to the system. Then all cards are activated and their audio signals are fed into the HD link.

clock.

DIP switch: When using the Performa core, only 48 channels can be transmitted from the

core to the D21m system. In order not to lose audio data, the channel selector of the HD card S has to be conﬁ gured to this mode by setting switch #1 of DIP switch S1 to the ON position.

The other three switches #2...4 have to remain in their default positions and

must not be changed.

Note: The default settings for the card versions 1.949.412.21 and 1.949.412.22 are

6.5.3 MADI HD Cards ( and ) 1.949.411, 1.949.413, 1.949.414

Please note: Starting with order nos. 1.949.41 1.24 and 1.949.413.23, r esp., the MADI HD

cards have been equipped with the lar ger dual-slot fr ont panel containing an additional RS422 control connector (left pictur e). At the same time the MADI HD card with RJ45 connectors (1.949.414) was introduced (right picture).

The D21m MADI HD card is plugged into an HD card slot in the remote I/O

box and provides the link to the hub frame. The two interfaces offer up to 64 audio channels with 44.1/48/88.2/96 kHz operation, together with embedded control and user-accessible serial connection in each direction.

The auxiliary interface can be used as a redundant link or, in 88.2/96 kHz

operation, to extend the number of channels from 32 back to 64.

In slave mode, the card extracts the system clock from the incoming MADI

signals and provides it to the entire remote I/O box. It detects all other I/O cards that are inserted into the D21m system and displays their presence on the front panel of the frame. Once all audio interface cards are plugged in, pressing the RECONFIG key on the front panel conﬁ rms the conﬁ guration to the system. Then all cards are activated and their audio signals are fed into the MADI link.

The card can also be switched to master mode; it then runs with an internal

48 or 96 kHz reference.

The D21m I/O frame may be equipped with either one or, for redundancy

purposes, with two primary power supply units.

The module used is a primary switching AC/DC converter with an input

voltage range of 90...264 V and a standard IEC mains inlet. Output is 24 V

adjustable elements; if the internal primary fuse should fail, the unit must be returned to the factory for repair.

The primary power supply unit(s) is/are plugged directly into the PSII PCB

1.949.402, where all required voltages for the frame are generated.

FAN/STATUS Connector: This front-panel connector (15-pin D-type f for 1.949.404; 9-pin D-type f for

1.949.403) is used to output an electrically isolated status signal when the primary power supply (or one of them) should fail. The contacts of a relay located on the LED/PSII PCB are available on this connector, as well as a +24 V

supply and ground. The relay is energized as long as all supply volt-

DC

ages are ok, pins 4 and 6 (or pins 1 and 2 on 1.949.403) are connected then. In case of failure of any of the frame’s supply voltages, pins 6 and 8 (or pins 2 and 3 on 1.949.403) are connected. Please note that only the connector of

the right-hand primary PSU can be used for the status signal, even if two primary power supply units are installed in the D21m I/O frame.

The 15-pin connector on the current version 1.949.404 allows the additional

supply of a fan unit (1.949.597) using a 1:1 m/f cable (89.20.1167, included with the fan unit).

6.7.2 LED/PSII PCB 1.949.402

The primary power supply unit(s) as well as the frame’s backplane PCB are

directly plugged to the PSII PCB. It generates all the DC voltages required by the frame from the 24 V it constantly monitors all supply voltages. As long as everything is ok, a relay is energized. In case of failure of any one of the supply voltages, the relay releases. Both NO and NC relay contacts are available on the FAN/STATUS front panel connector of the right-hand primary PSU only.

The PSII PCB contains no adjustable elements.

The LED part of the PCB (not shown here) is located behind the frame’s front

panel and connected with a ribbon cable to P1 of the PSII PCB; it indicates available/missing cards and supply voltages as well as the boot sequence and errors while booting.

6.7.3 Air Deﬂ ector/Filter Unit 1.949.599

If a D21m I/O frame has a power dissipation of less than 80 W, air deﬂ ector/

ﬁ lter units should be used on top of and below the frame. For frames dissipat-

ing more power, an air deﬂ ector/ﬁ lter 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 deﬂ ector/ﬁ lter unit may be used below the fan unit, increasing the air intake cross-section and thus improving the cooling efﬁ ciency.

For more information on cooling and guidelines for power dissipation estima-

tion

refer to chapter 1.2.2, paragraph “thermal considerations”.

6.7.4 Fan Unit 1.949.597

In cases where the power dissipation of a D21m 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 D21m frame. Seven fans draw air in from the front (ﬁ ltered) and from the bottom (unﬁ ltered) and blow it out upward. The bottom is open and allows installing an additional air deﬂ ector/ ﬁ lter 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 sufﬁ cient.

For power supply to the fans and fan status monitoring, two connectors – one

at the front, the second at the rear of the unit – are provided. They are connected in parallel, so either one can be used depending on the application. 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. 89.20.1167) 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.

6.7.5.3 GPIO Break-Out Box 1.949.588

For easier wiring of single GPI and/or GPO signals, this break-out box can

be used. 16 GPI signals and 12 of the 16 GPO signals of a GPIO card with relay outputs (1.949.436) are wired to single, 4-pin Combicon terminals (see below), providing the relay contacts or opto-coupler inputs, as well as GND and a short circuit-proof 5 V

If voltages exceeding 50 V (AC or DC) are switched, the break-out box must

be placed within a closed rack in order to avoid shock hazards by touching the contacts!

Four of the 16 GPO signals (GPO 1...4, marked in black on the front panel) are

connected to solid-state relays whose power terminals are wired to the Combicon terminals. These power contacts can switch AC loads from 24...240 V with a maximum total current of 5 A over all 4 relays.

For safety reasons, these four terminals have no additional GND and 5 V

supply. All remaining low-voltage terminals (GPI 1...16, GPO 5...16) are coded on pin #4 in order to prevent high-voltage connectors being inserted by mistake.

The high-voltage connectors must be coded, as shown below; six coding

elements (order no. 54.25.1100) are included with the break-out box.

6.8.1 HD Card 1.949.410

Please note that this card has been replaced by the D21m HD card S (

chapter 6.5.1) and is not available for new systems.

The D21m HD card provides the link to the DSP core systems. Each input and

output can handle up to 96 channels in each supported sampling frequency (in combination with the Performa core, the number of I/O channels is restricted to 48). The system clock used is taken from the host DSP system, so no extra synchronization is needed.

The card detects all other I/O cards that are inserted into the D21m system

and displays their presence on the front panel of the frame. Once all audio interface cards are plugged in, pressing the RECONFIG key on the front panel conﬁ rms the conﬁ guration to the system. Then all cards are activated and

their audio signals are fed into the HD link.

Host link interface cable type CAT-5 UTP Cable Cable length up to 10 m Connector RJ-45 Capacity of one CAT-5 connection 96 channels Current consumption (3.3 V) approx. 600 mA (5.0 V) <50 mA

Operating temperature 0...40° C

Performa Mode

Fixed positions, must not be changed!

LEDs: On if a valid signal is present at the input that is locked to the system clock.

Jumpers: When using the Performa core, only 48 channels can be transmitted from the

core to the D21m system. In order not to lose audio data, the channel selector of the HD Card has to be conﬁ gured to this mode by a jumper on the card.

The other two jumpers have to remain in their default positions and must not

be changed.
