CLASS I

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.

Installation/Maintenance/ESD

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 per-

formed 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 temperature and the relative humidity of the environment must be within the specified limits during operation of the unit. Relevant values are the ones at the air inlets of the unit.

• Condensation must be avoided. If the unit is installed in a location with large variation of ambient temperature (e.g. in an OB-van), appropriate precautions must be taken before and after operation (for details on this subject, refer to Appendix 1).

• Unobstructed air flow is essential for proper operation. Air vents of the unit 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).

• The unit must not be heated up by external sources of heat radiation (sunlight, spot lights).

B3 Earthing and Power Supply

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).

Class I Equipment (Mains Operation)

ESD/Repair

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.

Class III Equipment (Battery Operation up to 60 VDC)

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 electromagnetic 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 specified 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-

North American Standard

(NAS)

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 humidified 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 corresponding 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

Page 7

E Repair

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.

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 (ionizing).

• 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 the following paragraphs.

Ambient Temperature

Units and systems by Studer are generally designed for an ambient temperature range (i.e. temperature of the incoming air) of +5...+40 °C. When rack mounting the units, the intended air flow and herewith adequate cooling must be provided. The following facts must be considered:

• The admissible ambient temperature range for operation of the semiconductor components is 0 °C to +70 °C (commercial temperature range for operation).

• The air flow through the installation must provide that the outgoing air is always cooler than 70 °C.

• Average heat increase of the cooling air shall be about 20 K, allowing for an additional maximum 10 K increase at the hot components.

• In order to dissipate 1 kW with this admissible average heat increase, an air 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.

• If the cooling function of the installation must be monitored (e.g. for fan 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.

Frost and Dew

VIII

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

Page 11

Appendix

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 controlled 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

Appendix 2: Mains Connector Strain Relief

For anchoring connectors without a mechanical lock (e.g. IEC mains connectors), 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.

1 D19m SYSTEM BASICS

1.1 Introduction

The D19m series consists of single cards with a width of 100 mm (Eurocard width) that can be plugged into a 19” frame (3 or 1 height units). The output of the input cards feeds a time-division multiplex (TDM) bus. The purpose of this bus is to multiplex all the input signals, so that they can directly feed a MADI connection (multiplexer unit/MUX) via a MADI interface. Just the other way round, the signal coming from a MADI connection can be fed into the TDM bus, too, from where again all output cards can derive their information (demultiplexer unit/DEMUX). Beyond that, most card types can be used in standalone applications, too.

TDM Bus The TDM bus is a 16-bit wide bus with 128 time slots. The format is simi-

lar to the AES/EBU format, however distributed in parallel on two words. This means that 64 audio channels with 24 bits plus additional information (U-bits, C-bits etc..) can be transferred. The time slot allocation is given by the card addresses hardwired on the backplane. Thus an A/D converter card plugged into the first slot automatically gets the address 0 and writes to the bus only during its own, assigned time slots. Since ADAT and TDIF input cards occupy multiple channels on the bus, their address must be set with on-card DIP switches. All remaining cards are 4-channel and can be easily exchanged, e.g. an analog card may be replaced by a digital card. The clock signals (CK128, frame and sync) are sent by the MADI card (unless it is switched to slave mode) or the MADO card and are distributed on the backplane. The AES/TDM signal selects between standalone and TDM bus operation for the individual cards. This signal is controlled by the MADI or MADO card, too. It decides e.g. whether the D/A converter card takes its input signal from the TDM bus or from the AES/EBU input, or whether the A/D converter card may write to the TDM bus or not. If individual cards in the rack should operate in standalone mode, an additional jumper is available on the backplane in order to interrupt this select signal for every card individually.

D19m Technical Description

Synchronization Except for the AESI and AESO cards, all cards have a separate sync input.

Depending on the jumper setting, this input receives the sync signal from the bus (AES/EBU signal with TTL level) or from a separate input (standard balanced AES/EBU signal according to AES11). Thanks to the AES/EBU inputs and outputs, the converter cards also can operate in standalone mode. It is possible to extract a sync signal from the MADI (when using MADI optical). However, this feature should be used only for large distances and stagebox systems. Otherwise it is recommended to use the AES/EBU sync line. This results in a smaller error probability (having two PLLs less in the path), reduced jitter, and allows the use of variable speed.

Split Rack Configuration A MADI and a MADO card can share the TDM bus in a common "split

rack". The available channels have to be split for MUX and DEMUX channels. In such a system, using the MADI card’s sync out should be avoided whenever possible. Since the MADO card is always considered as a master by the software, a hardware modification is necessary in such a case. Therefore, it is recommended to use separate racks for MUX and DEMUX (refer to example in chapter 2.3.1).

D19m Technical Description

Routing The MADI card transfers the MADI input signal to the TDM bus, and the

1.2 D19m 3U Frames

MADO card converts the TDM bus signal to the MADI format. Without external control, the channels will transmit the signals in the MADI data stream and on the TDM bus in the same sequence. When using the RS485 interface it is possible, however, to arbitrarily change the allocation on the MADO card (application e.g. in Route56).

The same frames can be used for MUX and DEMUX units. The 19” frames have a height of 3U and are equipped with backplane, two power supply units (+5 V, ±15V), and a connector panel with supply and control connectors.

The D19m series cards are plugged to the backplane. On the rear side of the backplane, connectors for the power supply, the audio and control signals can be found. Apart from the supply, also the clock, synchronization, and control signals are distributed. A jumper determines for each card whether it is linked to the TDM bus or operating in standalone mode.

1.2.1 Power Supplies

The 3U frames contain two supply units: +5 V/20 A (1.940.606 or, in earlier racks, 1.940.601) ±15 V/3.4 A (1.940.607 or, in earlier racks, 1.940.602)

The supply units are plug-in modules. For redundant supply configurations, a special rear panel is required.

1.2.2 Connector Panels

For audio signals, a variety of connector panels can be used (see chapter

1.4).

1.2.3 Backplane 1.940.550

(installed in Rack versions 1.940.592.xx-V and 1.940.595.xx-V) The .550 backplane is used for applications with up to 16 audio cards.

However, it cannot be used together with the RCC controller card and Mic/Line input cards.

16 identical card locations are available. The sync input is connected to the last, i.e. the 16th card location. The card address is given by the backplane hardwiring, i.e. by the card’s position within the frame. There is only one jumper per card for selecting stand-alone or TDM bus mode.

The DIP switches DS1 and DS2 are reserved for configurations with multiple MADI cards. For pinout details of the flat cable connectors please refer to chapter 1.4.

1.2.4 Backplane 1.940.551

(installed in Rack versions 1.940.591.xx-V and 1.940.594.xx-V) This frame is intended for the application of the RCC controller card and Mic/Line input cards. This backplane has additional connectors for the second output (“split out”) and the mute input of the pre-amps. With this backplane the addresses are jumper-selected, allowing a more flexible allocation of the card positions, in particular with the Mic/Line input cards. The last, i.e. the 16th card location is reserved for the controller card. The sync input is connected to the 15 card location.

1.3 D19m 1U Frame

The system consists of a 1-unit 19” frame containing a power supply and a backplane (mother board) on which the complete TDM bus is wired. Up to four cards from the D19m family can be inserted. The ±15 V and +5 V supplies are integrated. The mains voltage range is 90 to 250 VAC. A sync input amplifier and a small processor system for the control of the Mic/Line cards is contained as well. The built-in fan is temperature-controlled, an overheat condition is indicated by a front-panel LED. For rear-panel wiring, the standard D19m system connector panels can be used (see chapter 1.4).

Typical Configuration Examples: 2 × Mic/Line cards and 2 × A/D cards in stand-alone mode, or

1 × MADI In card and 3 × D/A cards, or 3 × ADAT In cards and 1 × MADI Out card.

If slots 3 and 4 are equipped with Mic/Line cards, their line outputs will not be available. In such a case the resistors R173, 273, 373, and 473 must be removed on the Mic/Line cards. Instead, the 0 Ω bridges R174, 274, 374, and 474 must be inserted in order to have the line out signal at the card’s direct out pins. The audio connectors (P2, P4...P11, P14) have the same standard pin assignment that is used for the 3U frame. This means that all the connector panels from the D19m system can be used for the 1U frame as well. For more information on the audio connector pinout, please refer to chapter

1.4.

P13: P13 allows to connect two AES/EBU inputs or outputs to the slots 3 and 4

with a flat cable. If this connector has to be connected directly to a 15-pin D-type connector on the rear panel, a special adapter must be assembled. The easiest way to achieve this is using a 15-pin flat cable pressed to the D-type connector. On the other end, cut off the 15th wire; the remaining 14 wires are split in the

Further Wiring: For special applications, several signals are routed to solder pads (W...). So

it is possible, for instance, to wire the MUTE signals of the Mic/Line cards, or to use the GPIO signals on the Supply Board.

W1...W20 can be used for mute signals (MP4RC four-channel mic amplifier cards) or

for AES/EBU sync inputs (all cards, except AESI and AESO cards).

W21, W22 / W42, W43 For synchronizing the cards, an AES/EBU signal is fed via a MADI or a

MADO card in slot 4. For this application the pins of the XLR connector must be wired to solder pads W42 and W43. P1 and P2 on the Supply Board must not be connected. If neither a MADI nor a MADO card is installed, for synchronization the receiver on the Supply Board can be used. For this case, the pins of the XLR connector must be wired to the solder pads W21 and W22, and pins P1 and P2 of the Supply Board must be connected, the default input termi-

D19m Technical Description

Address Setting: When using the TDM bus or Mic/Line cards, the slots have to be addressed.

This is done with solder bridges (i.e., pad pairs that can be connected with a tiny drop of solder) on the component side of the backplane board, accor ding to the following table:

Slot LSB ... Address ... MSB TDM

1 JP 1 JP 2 JP 3 JP 4 JP 5 2 JP 6 JP 7 JP 8 JP 9 JP 10 3 JP 11 JP 12 JP 13 JP 14 JP 15 4 JP 16 JP 17 JP 18 JP 19 JP 20

Connected pad pairs correspond to a logical „0“. The solder bridges JP5, 10, 15, and 20 are used to switch over from stand-

alone to TDM operation; if these bridges are connected, this means „TDM operation“.

Supply Board 1.940.578 On the Supply Board, a +5 V (IC8) and a ±15 V supply (IC19, Q8 and T2)

are implemented. Furthermore, a small processor system (IC16, IC9, IC10, IC11) is controlling the Mic/Line cards, and converting the RS422 signals to the I2C protocol.

The RS422 interface (IC2) can be replaced by an RS232 interface (IC1) or a MIDI interface (IC4, IC5).

The baud rate can be set to 31.25 kBd (jumper P8-P9 inserted) or to

38.4 kBd (jumper P7-P8 inserted). In addition, two relays for the general-purpose output can be installed. For synchronizing the cards in stand-alone mode, an AES/EBU input is

provided; its termination impedance can be switched to high-Z (jumpers P5P6 off, P4-P5 on). If a MADI or MADO Card is used in the system, the sync signal sent to the backplane must be disabled (P1-P2 on, P2-P33 off).

The DIP switches are only used for factory tests and must always be set to OFF.

Connector Panels For audio signals, the same connector panels as known from the 3U frame

system can be used (see chapter 1.4). In addition, a 15-pin D-type connector panel is available, allowing to wire four AES/EBU inputs or outputs; so it is possible to realize, e.g., eight XLR inputs and four AES/EBU outputs in a single 1U unit.

D19m Technical Description

1.4 Connector Panels

All audio and some control (sync, mute) signals are fed to flat cable connectors on the rear (solder) side of the backplane PCBs. A range of connector panels can be mounted at the rear of the frames; they are used for linking the frames to the outside world. All connector panels come with flat cables that plug into the flat cable connectors of the backplane PCBs.

As not only analog, but also digital audio and control signals are used, the pin assignment of the 16-pin (audio I/O) and 6-pin (sync) or 10-pin (sync or mute) flat cable connectors on the different backplanes is not identical in each case and needs some consideration. Please note as well that each sync/mute and sync connector is used for two cards.

2.1 A/D and D/A Cards

2.1.1 D19m C4AD/24 – Quad 24 bit A/D Converter 1.940.562

The A/D card uses high-end 24 bit Delta-Sigma converters and can be used for standalone applications as well as for the D19m rack. On one card, four analog inputs (mono) are converted to two AES/EBU outputs; if a MADO card is used in the system, these signals can be converted to a MADI link. If the external sync signal fails or if the card is used in standalone applications, the sampling frequency will be generated on-board. For such cases the sampling frequency can be selected at the front panel (44.1 or 48 kHz). The channel status information contains the sampling frequency as well as source channel information depending on the card address.

D19m Technical Description

Jumpers: Input level 3 positions: 15 dBu (fixed), 21 dBu (fixed), or variable (0...26 dBu).

Sync AES / TTL AES: The sync input from the AES/EBU sync input is used (in case of

standalone use of the A/D card). TTL: The sync input from the D19m rack is used. The internal TTL sync signal is generated by the MADO card in a D19m MUX frame respectively by the MADI card in a DEMUX frame.

2-CH / STEREO Defines the channel mode in the channel status bit.

Alignment: Set jumper to 15 dBu or 21 dBu. Feed an analog signal with a level of

+6 dBu or +12 dBu, respectively, to one of the analog inputs. Measure the digital level either locally on the AES/EBU outputs or via the TDM bus on the MADI output. Adjust the level with the corresponding FINE ADJUST trimmer potentiometer to –9 dBFS. If no digital measuring equipment is available, feed an analog signal with a level of +15 dBu or +21 dBu to the analog input and adjust the level with the corresponding FINE ADJUST trimmer potentiometer so that the overload LED just comes on. If an other input sensitivity has to be adjusted, set the jumper to position VARIABLE and use the 0...26 dBu trimmer potentiometer to adjust the de sired level.

2.1.2 D19m C4AD NS/24 – Quad 24 bit A/D with Noise Shaping 1.940.563

The A/D card uses high-end 24 bit Delta-Sigma converters and can be used for standalone applications as well as for the D19m rack. On one card, four analog inputs (mono) are converted to two AES/EBU outputs; if a MADO card is used in the system, these signals can be converted to a MADI link. The converted signal is also available as 16 bit word by using dithering or dithering and noise shaping algorithms. If the external sync signal fails or if used in standalone applications, the sampling frequency will be generated on-board. For such cases the sampling frequency can be selected at the front panel (44.1 or 48 kHz). The channel status information contains the sampling frequency as well as source channel information depending on the card address.

Dithering and The card is equipped with 24-bit converters. If there is a need for 16 bit

Noise Shaping: resolution, dithering and noise shaping or dithering only can be activated.

Dithering helps to improve the low level signals whereas noise shaping allows to have almost the dynamic range of a 24 bit converter in the mid frequency range.

2.1.3 D19m C4DA/24/96 – Quad 24 bit D/A, 96 kHz Operation 1.940.571

The C4DA/24/96 card can be used for standalone applications as well as in the D19m rack for TDM application. On one card, four digital channels are converted to four analog outputs. The converters receive their input signals either from the AES/EBU inputs (standalone application) or from the TDM bus. The C4DA/24/96 card can be used next to the other D19m cards in a D19m rack. If in standalone applications the synchronization should fail, the clock will be generated from one of the AES/EBU inputs. The channel status bits contain the source channel defined by the card address as well as the sampling frequency information.

96 kHz Operation: The card can be used for sampling frequencies of 32 through 48 kHz. For

standalone operation, also twice these values are allowed. When using the AES/EBU inputs in standalone mode, only the mode with two channels per line (transmitted with twice the transmission speed) is supported, but not the mode with one channel per line (CH1 in AES/EBU format corresponds to the first, CH2 to the second sample).

SYNC AES1 is ON when the external sync fails, and the sync of the AES1 input is used

to synchronize the card.

SYNC AES2 is ON when the external sync fails, and the sync of the AES2 input is used

to synchronize the card (if no signal is connected to AES1).

SUPPLY Indicates “power on” status.

Jumpers: Output level 15 dBu fixed, 21 dBu fixed, or 0...26 dBu variable.

SYNC AES / TTL AES: The unit will be synced from the AES/EBU input (in case of standa-

lone use of the D/A card). TTL: The sync input from the D19m rack is used. The internal TTL sync signal is generated by the MADO card in a D19m MUX frame or by the MADI card in a DEMUX frame.

48 k / 96 k For correct 96 kHz operation, the “96 k” jumper must be set for standalone

application.

COMMON / SINGLE When setting the jumper to “common”, a common switchover for several

cards is allowed by pulling pin 18C on the backplane to GND; in such a

case, the 48/96 k jumper must be set to the 48 k position.

Alignment: Feed a digital audio signal with a level of –10 dBFS either via one of the

AES/EBU inputs or via the TDM bus to the C4DA/24/96 card. Set the jumpers to either 15 or 21 dBu and measure the corresponding analog outputs. Use the corresponding FINE ADJUST trimmer potentiometers to set the output to +5 or +11 dBu, respectively. If a different output level is required, set the jumper to position VARIABLE and use the 0...26 dBu trimmer potentiometers to adjust the desired level. Repeat this alignment for the second AES/EBU input.

2.1.4 D19m MP4RC – Quad Remote Controlled Mic/Line In 1.940.575

The Mic/Line inputs (pre-amps) are equipped with 4 high-quality preamplifiers. The gain can be controlled in 1 dB steps over a wide range. The inputs are transformer-balanced and switchable between microphone and line level sensitivity. Phantom power, high-pass filter and gain are remote controlled for each channel individually. A simple limiter (clip protection) can be activated for all 4 channels in common. Control of the Mic/Line inputs is performed by an I²C bus coming from the D19m RCC remote controller card

1.940.576 via the backplane. A mute input signal per Mic/Line input permits to mute the signal independent of the remote control signal. The line output is electronically balanced. The Split Out supplies, regardless of the current gain setting, a signal which is 26 dB above the mic input signal or 1 dB above the line input signal).

2.1.5 D19m RCC – Remote Ctrl. Card for MP4RC Mic/Line In 1.940.576

The purpose of the RCC card is controlling up to 14 Mic/Line input cards (pre-amps). Gain, high-pass filter, phantom powering and limiter (clip protection) can be set. In contrast to the audio cards, this card must be inserted into the 16th slot, i.e. the last one on the backplane, and it works only in conjunction with the backplane version 1.940.551. Control of the Mic/Line inputs is performed by an I²C bus on the backplane. For various signaling purposes, 8 opto-coupled inputs and 8 relay outputs can be used. An AES/EBU signal can be distributed to 4 outputs, primarily used for sync signal distribution. The standard 110 Ω input impedance of this AES/EBU input can be switched to hi-Z by means of a jumper, which allows to use the same signal also for syncing e.g. a MADO card. Usually the D19m rack is controlled by a D950 mixing console (stagebox system). In this application, an RS422 signal is used for control. This control signal can be transmitted in balanced mode or via an optical interface. For other purposes, RS232 or MIDI control is possible as well. The baud rate of the control link can be jumper-selected to 31.25 or 38 kBaud. If more than one stagebox is used, they must be linked to the mixing console in a star configuration.

2.2.2 D19m AESI SFC – Dual AES/EBU In w. Asynchronous SFC 1.940.540

The AESI SFC card can be used for standalone applications as well as for the D19m rack. It routes two asynchronous AES/EBU input signals to the TDM bus, where they are read from a MADO card and can then be output through a MADI link. At the same time, each of the two AES/EBU inputs is fed to two AES/EBU outputs. The AESI SFC card can be used next to the other D19m cards in a D19m rack. Incoming AES/EBU signals are converted via a sampling frequency converter either to an internal sampling frequency (32 kHz, 44.1 kHz, or 48 kHz, selectable with a front panel switch), or to the sampling frequency of an external sync signal. When the external sync signal fails, the internal sync reference will be used automatically. The input and output sampling frequencies can be between 25 kHz and 55 kHz, and their ratio must be between 0.5 and 2. The channel status information will be transmitted from the inputs to the outputs, and the sampling frequency information will be corrected correspondingly.

2.2.4 D19m AESO – Dual AES/EBU Out, w. Dithering or SFC 1.940.470

The AESO card has been developed for the use in the D19m rack. On one card, four channels coming from the TDM bus are converted to two AES/EBU outputs. The signal on the TDM bus is normally coming from the MADI card (input). For each of the two AES/EBU outputs individually, either reduced word length with dithering, or sampling frequency conversion can be jumperselected. In dithering mode, output signal resolution is 16 or 20 bit (with dithering), or 24 bit (without dithering), depending on the front-panel switch setting. In sampling frequency converter (SFC) mode, the output sampling frequency is identical to the one of the signal at the AES/EBU sync input.

2.3 MADI I/O Cards

2.3.1 D19m MADI – MADI In for Coaxial Cable 1.940.500

The MADI card is used as a demultiplexer for the MADI input signal in a D19m rack. The MADI input signal will be converted to the TDM bus. AESO cards as well as A/D cards (output cards) receive their signals from the TDM bus. Any MADI channel can be routed to any output card. The MADI card is equipped with a coaxial input (BNC connector) as well as a BNC “through” output. In standard applications the MADI card is synchronized via the AES sync input of the D19m rack. It generates the required clock signal for the TDM bus as well as the TTL sync signal for the output cards. If the MADI card is set to SLAVE mode, it will receive the sync and clock signals from the backplane. Via the RS485 interface the MADI card can be remote controlled. In that case the frame address will be set via the DIP switches on the backplane.

2.3.2 D19m MADI – MADI In for Optical Fibre Cable 1.940.511/1.940.512

The MADI card is used as demultiplexer for the MADI input signal in a D19m rack. The MADI input signal will be converted to the TDM bus. AESO cards as well as A/D cards (output cards) receive their signals from the TDM bus. Any MADI channel can be routed to any output card. The MADI card 1.940.511 is equipped with an optical input (SC connector) as well as an optical “through” output. Version 1.940.512 (D19m MADI RED) has an additional MADI input for redundancy. In standard applications, the MADI card is synchronized via the AES sync input of the D19m rack. It generates the required clock signal for the TDM bus as well as the TTL sync signal for the output cards. If the MADI card is set to SLAVE mode, it will receive the sync and clock signals from the backplane. If necessary, the sync signal can be extracted from the MADI stream. However, this method is recommended only for long distances and stagebox applications, because the fault tolerance is lower and the jitter is higher (2 PLLs involved). Besides, varispeed is impossible in such a case. Via the RS485 interface the MADI card can be remote controlled. In that case the frame address will be set via the DIP switches on the backplane.

The earlier version 1.940.510 is equipped with an ST connector instead of the SC connector (jumper diagram at the end of this chapter).

The “MADO” MADI output card serves as multiplexer in a D19m rack. The TDM bus data, written by analog or digital input cards to the bus, are read and output as a MADI signal. The channel allocation can be selected by the control software. The card is synchronized by the sync input and distributes the clock signals required for the TDM bus. Four additional AES/EBU sync outputs are available. If the external sync signal is invalid, the internal generator is automatically activated and generates a sync signal. Since the frequency accuracy is ±1 ppm and an AES/EBU signal is output as sync signal, this can be used for the synchronization of a studio. The MADO cards can be controlled by RS485 from an external device. The frame address is set by a DIP switch on the backplane.

2.4 TDIF I/O Cards

2.4.1 D19m TDIFI – Dual 8-Channel TDIF In 1.940.480/1.940.481

Two TDIF inputs are routed to the TDM bus, where they are read from a MADO card and can then be output through a MADI link. The second version of this card (1.940.481) is equipped with additional AES/EBU outputs for standalone applications. For this purpose, also an AES/EBU receiver for synchronization, output transformers, and drivers are provided. The input sampling frequency can be between 28 kHz and 55 kHz. The TDM output occupies the addresses of 4 slots (16 signals). The addresses are set via DIP switches. In cases where only one TDIF input is needed, it is possible to use eight TDM signals only by setting a jumper (8/16CH) on the card.

Sync: The synchronization comes usually from the TDM bus. In standalone appli-

cations an AES/EBU sync input provides the synchronization.

Configuration: On standard cards, the card address is given by the physical slot on the

backplane itself; this means that the card in slot 0 occupies the channels 1 to 4, the second slot corresponds to channels 5 to 8, etc. Since the TDIF card provides 16 inputs instead of 4, the card addresses have to be configured via DIP switches (card addresses 0 to 12).

Please be careful to correctly set the card addresses because of potential conflicts with other cards. Typically, the lower slots are used for standard 4-channel cards; the TDIF interfaces are moved to the higher addresses.

TDIF Interface PCB Both a TDIF input and a TDIF output card can be connected to one of the

two 25-pin D-type sockets on the TDIF Interface PCB 1.940.632. In this way, the inputs and outputs of two 8-channel digital recorders (e.g. DA-88) may be connected with one single cable each. For the connection to the backplane, two 16-pin flat cables are used. Furthermore, the TDIF Interface PCB connects to a BNC connector panel handling the sync signals.

Note: The TDIF interface is suitable for short distances only. Even with high-

quality cable, a length of 5 m must not be exceeded.

DA-88 Synchronization: When using, for example, a DA-88 unit, a word clock signal must be sent

over a separate line, because the DA-88 cannot sync to the LRCK signal. For this purpose, the BNC Board 1.940.633 is available. It can be connected to the TDIF Interface Card 1.940.632.

Note: The phase position of the word clock signal is very critical. No other word

clock signal must be used in this application.

2.4.2 D19m TDIFO – Dual 8-Channel TDIF Out 1.940.485/1.940.486

The TDIFO card converts the TDM bus signals to the TDIF format. 2 × 8 channels can be processed simultaneously, audio resolution is 24 bit. Emphasis information is taken from the first channel, because the TDIF format has a common emphasis information for all channels only. The card is synchronized with the frame and the CK128 clocks of the TDM bus. The addressing must be done with four DIP switches on the backplane. For this card, it cannot be performed automatically because more than four audio channels are processed. The second version of the TDIFO card (1.940.496) is designed for standalone mode. It is equipped with four additional AES/EBU receivers per TDIF output. A jumper on the backplane switches the ITDM signal that selects whether the card reads from the TDM bus or from the AES/EBU receivers. In standalone mode, a separate AES/EBU signal is used for synchronization of the card. The source of this sync signal is selected with a jumper, either from the TDM bus or from a separate input. If the sync signal should be missing, the synchronization is automatically taken from the first AES/EBU input.

Synchronization: When using, for example, a DA-88 unit, a word clock signal must be sent

over a separate line, because the DA-88 cannot sync to the LRCK signal. For this purpose, the BNC Board 1.940.633 is available. It can be connected to the TDIF Interface Card 1.940.632.

Note: The phase position of the word clock signal is very critical. No other word

clock signal must be used in this application.

2.5 ADAT I/O Cards

2.5.1 D19m ADATI – Dual 8-Channel ADAT In 1.940.490/1.940.491

Two optical ADAT inputs are routed to the TDM bus, where they are read from a MADO card and can then be output through a MADI link. The card 1.940.491 is equipped with additional AES/EBU outputs for standalone applications. For this purpose, also an AES/EBU receiver for synchronization, output transformers, and drivers are provided. The input sampling frequency can be between 25 kHz and 55 kHz. The ADAT format does not contain channel status information, the C-bits are set to default (not indicated). Max. 24 bits of audio are transmitted. The TDM output occupies the addresses of 4 slots (16 signals). The addresses are set via DIP switches. If only one optical input is needed, it is possible to use eight TDM signals only by setting a jumper (8/16CH).

Synchronization: The synchronization comes usually from the TDM bus. In standalone appli-

cations an AES/EBU sync input or the optical input provides the synchronization.

Configuration: On standard cards, the card address is given by the physical slot on the

backplane itself; this means that the card in slot 0 occupies the channels 1 to 4, the second slot corresponds to channels 5 to 8, etc. Since the ADAT card provides 16 inputs instead of 4, the card addresses have to be configured via DIP switches (card addresses 0 to 12).

Please be careful to correctly set the card addresses because of potential conflicts with other cards. Typically, the lower slots are used for standard 4-channel cards; the ADAT interfaces are moved to the higher addresses.

2.5.2 D19m ADATO – Dual 8-Channel ADAT Out 1.940.495/1.940.496

The ADATO card converts the TDM bus signals into the optical ADAT format. The card supports two 8-channel outputs for (plastic) optical fibre with a word length of up to 24 bits. The synchronization is taken from the TDM bus (CK128 clock). A PLL increases the clock rate to 256 × FS. The channel status bit is not supported by the ADAT format. The addressing must be done with four DIP switches on the backplane. For this card, it cannot be performed automatically because more than four audio channels are processed. The card can also be equipped with eight AES/EBU receivers and a separate sync input for standalone applications (order no. 1.940.496). The ITDM jumper on the backplane decides whether the sync signal is taken from the TDM bus or from the card itself. If it comes from the card itself, the sync is either taken from the separate sync input (as long as a valid signal is available) or from the first AES/EBU input.

2.6 Miscellaneous Cards

2.6.1 D19m Sync Receiver 1.940.557

The sync receiver distributes an AES/EBU sync signal on the backplane and is required if several cards are used in standalone mode, without a MADI or a MADO card. This unit prevents that a separate sync signal must be wired for each card.

2.6.2 Optical/Coax Interface 1.940.558

5 V

The Optical/Coax Interface is used for converting MADI signals from optical into electrical signals and vice versa. It is a Euro card unit normally used for standalone application, e.g. in a 1U high ASC rack. For integration into a system, additional information is required; please apply to Studer in such a case. It can be powered either with 5 VDC or a with variable supply voltage of

10...35 VDC, depending on the jumper setting.

D19m Technical Description

Temperature Monitoring: For temperature monitoring, an NTC (57.99.0801) can be connected be-

tween pin11 and one of the GND pins. The NTC has to have the following specs: Nominal resistance: 330 kΩ, @ 50° C: 100 kΩ, @ 60° C: 65 kΩ.

Supply: The usual supply voltage is 15 V. In a MUX or DEMUX rack, usually the

negative supply rail is less loaded, so it can be sensible to connect the Fan Module to the negative supply rail as follows: Pin1 (+15 V) to supply GND, and one of the GND pins (3, 7, 9, or 13) to the –15 V supply.

Higher Supply Voltages: Supply voltages up to 30 V may be used.

However, the “max. fan” jumper must always be set to OFF in such a case; otherwise, the fans would get too high a full-speed operating voltage at over-temperature conditions. The alarm relay and the alarm LED series resistor, too, must then be matched to the corresponding, higher operating voltage.

3 STAGEBOX APPLICATION FOR D950 MIXING SYSTEM

Some points have to be considered for a stagebox setup with the mixing console D950:

• The D950 is always the star point if multiple stageboxes are used; the Stageboxes cannot be connected in series, because the control signals cannot be transferred from one Remote Controller Card (RCC) to another, and the control signals for two cards cannot be merged.

• A frame can hold input and output cards (mixed arrangement); in such a case, the ratio of inputs to outputs is defined in the MADO software (EPROM).

• The connection to the D950 can be done in two ways. Standard is to use four optical fibre cables for MADI and control signals (MADI in/out, control receive/transmit). The other way is to use four separate copper cables or a combination of both for the four signals. The control signals are standard RS232/RS422 or MIDI connections. This also gives the possibility to connect the system to another mixing console, provided the correct software protocols are implemented.

• Cooling is a important point to be carefully considered in designing a stagebox. A fan is absolutely necessary as soon as the system holds more than

5...6 Mic/Line and A/D pairs.

• It is possible to combine D19m Mic/Line cards with D19 MicADs in a D950 system. However, in such a combination separate control lines are re quired for the two systems.
