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

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).

Repair/Disposal

E1 SMD Components

Studer has no commercially available SMD components in stock for service purposes. For repair, the corresponding devices have to be purchased locally. The specifications of special components can be found in the service manual. SMD components should only be replaced by skilled specialists using appropriate tools.

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

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.

NEW FEATURES WITH SW V4.02/V4.03

1 Momentary/Latching Key Functions

1.1 PFL and Talkback Keys

Latching: If a PFL key or one of the talkback keys (N–1 A, N–1 B, AUX 1, AUX 2,

or STUDIO) is pressed for less than 0.2 s, the function is now latching, and the key is illuminated. To release the function, an other short press of the key is required. The same functionality applies for the F1...F5 keys if configured as additional talkback keys. For this purpose, please refer to the “MONITOR

EXPANDER page, Talkback Functions” paragraph below.

Momentary: When pressing a PFL or TB key longer than 0.2 s, it acts as a momentary

key, i.e., the function is automatically canceled upon releasing the key.

Basic information on this subject to be found in chapters: 3.1.4 / 6.1 / 6.3

OnAir 1000 Digital Mixing Console

1.2 Monitoring Keys

Mutually Releasing / Latching: If one of the Monitoring Selector keys is pressed for less than 0.2 s, the

former monitoring source selection is canceled, and the new monitoring source selection becomes active. The selection is latching and the key is illuminated until any other Monitoring Selector key is pressed.

Mutually Releasing / Momentary:If one of the Monitoring Selector keys is pressed for longer than 0.2 s, it acts as

a momentary key. The former monitoring source selection is canceled, and the new monitoring source selection becomes active. Upon releasing the key, the former monitoring source selection is reactivated.

Uhm... This may sound a bit confusing, but in everyday use it is a very convenient

feature – just give it a try!

2 Talkback and PFL Signaling

2.1 Talkback Signaling from CR to Studio, and Vice Versa

CR to Studio: When talkback from the control room (CR) to the studio is activated, pin 23

of the STUDIO MON CTRL connector is activated (i.e. pulled to ground). This pin was formerly labeled as “Spare OUT 1”. Now it can be used for illuminating the CR lamp on an external talkback box.

Please refer to the pin assignment diagram and table on the next page.

The MONITOR EXPANDER page, possibly known from your experience

with OnAir 2000M2 consoles, can now be opened on the OnAir 1000 consoles as well. For this purpose, the SYSTEM CONFIG. Page has an additional “MONITOR EXPANDER” button, as shown below:

When touching this button, the MONITOR EXPANDER page opens and

allows to assign three different functions to any of the F1...F5 buttons:

TB FROM CR TO ALL AUX, TO ALL N–1, or TO ALL (meaning all

AUX and all N–1), or NONE (no function at all).

However, no Monitor Extension module can be installed in an OnAir 1000

console, which means that no other functions (as known from OnAir 2000M2 consoles) can be configured.

Code 0x00008000: If this code is active, the status of the channel ON/OFF switch of channels

currently not routed to the console surface will be saved in the flash memory when powering the console off. At power on, the ON or OFF status of these channels will automatically be re-established. If this code is inactive, the channels not routed to the console surface will always be set to OFF at power on.

1 INTRODUCTION

OnAir 1000 Digital Mixing Console

The OnAir 1000 is a smart but yet powerful digital mixing console for “on-air” and small recording and editing studio applications. It has ten input channels, each with two physical inputs, and two master faders.

There are two different basic versions available:

• An analog-biased version with five analog stereo line and two digital

input channels, and

• A digital-biased version with two analog stereo line and five digital

input channels. Both versions feature three mono microphone input channels with switchable high-pass filter and phantom power. Both versions can be ordered with double, redundant mains power supply. For more information on this subject, please refer to chapter 14.2.

The OnAir 1000 can be integrated seamlessly with a broadcast automation system (CAB) like Studer’s DigiMedia.

The OnAir 1000 is based on a touch-screen user interface. Only the most important functions have hardware control elements, making it very easy to use. It has everything integrated in a single, lightweight console and does not need any external racks or power supplies (except the Redundant Supply versions, refer to chapter 14.2).

Since it is fully digital, it can individually be adapted to the current user using snapshot automation. Extensive configuration possibilities allow the OnAir 1000 to be integrated into almost any broadcast studio environment.

For an overview, please refer to the OnAir 1000 block diagram located on the following two pages.

OnAir 1000 Digital Mixing Console

1.2 Definition of Terms

Terms used in this manual:

Inputs: The physical inputs of the input unit; all input units have mono or stereo

inputs with A/B selection. Analog inputs are equipped with 3-pin XLR connectors. Digital inputs are equipped with AES/EBU inputs on XLR connectors, and S/PDIF inputs on Cinch/RCA and optical (TOSlink) connectors.

Input Unit: An input unit is a hardware assembly installed within the console. All in-

put units contain two selectable mono or stereo inputs; all input signals to the input units are connected to the input connectors at the rear of the console. Microphone input units have transformer-balanced mono inputs on XLRs, with selectable 48 V phantom supply and A/B selection. Analog Line input units have two electronically balanced stereo inputs on XLRs, with A/B selection. On Digital Line input units, there is a selection of AES/EBU inputs on XLR connectors, and S/PDIF inputs on Cinch/RCA and optical (TOSlink) connectors available. Each (A or B) input of every input unit is equipped with general-purpose control inputs and outputs (GPIO) that can be used for fader start, mute, signaling, etc.; these control inputs and outputs are available on D-type connectors.

Input Channel: An input channel is the combination of all signal processing functions that

can be assigned to a fader strip, as A/B input selection, gain, filter, EQ, pan/balance etc.; each input channel can be routed to any fader strip thanks to the input channel routing performed in the DSP section of the console.

Fader Strip: A fader strip contains the operating elements for an input channel, as a

linear fader and a few keys and LEDs (e.g. ON, OFF, and PFL keys, and OVL and AUTO TAKEOVER LEDs). As the number of operating elements is reduced to a minimum, the adjustment of some less often used input channel functions, as e.g. EQ setting, is performed on the center touch-screen and the rotary encoders located next to this screen.

2 GENERAL

2.1 Utilization for the Purpose Intended

The OnAir 1000 mixing console is intended for professional use. It is presumed that the unit is operated only by trained personnel. Servicing is reserved to skilled technicians. The electrical connections may be connected only to the voltages and signals designated in this manual.

2.2 First Steps

2.2.1 Unpacking and Inspection

Your new mixing console is shipped in a special packing that protects the unit against mechanical shock during transit. Care should be exercised when unpacking so that the surfaces do not get marred. Verify that the content of the packing agrees with the items listed on the enclosed shipping list. Check the condition of the equipment for signs of shipping damage. If there should be any complaints you should immediately notify the forwarding agent and your nearest Studer distributor. Please retain the original packing material because it offers the best protection in case your equipment ever needs to be transported.

OnAir 1000 Digital Mixing Console

2.2.2 Installation

Primary Voltage: The power supply unit is auto-ranging; it can be used for mains voltages in

a range of 100 to 240 VAC, 50 to 60 Hz.

DC Operation: The console can be operated from a 24 VDC source through the respective

24 VDC connector provided on the rear panel.

For DC operation it is mandatory that a UL approved, external fuse is connected in series with one of the supply lines (T 10 A H 250 V UL/CSA). The power switch next to the power inlet only switches the mains voltage; for DC operation, an external power switch has to be foreseen by the installer.

Dual (Redundant) Power Supply: For information on the Dual Power Supply versions refer to chapter 14.2.

General Precautions: Do not use the unit in conditions of excessive heat or cold, near any source

of moisture, in excessively humid environments, or in positions where it is likely to be subjected to vibration or dust. The ambient temperature range for normal operation of the unit is +5...+40° C.

Unobstructed air flow is essential for proper operation. The air vents on the top and bottom of the unit are a functional part of the design and must not be blocked in any way (e.g. by a manual or a computer screen).

Cleaning: Do not use any liquids to clean the exterior of the unit. A soft, dry cloth or

brush will usually do. For cleaning the touch-screen display window, most of the commercially available window or computer/TV screen cleaners are suited. Use only a

slightly damp (never wet) cloth. Never use any solvent!

Date printed: 23.10.03 SW V 4.0 General 2-1

OnAir 1000 Digital Mixing Console

Power Connection: The attached female IEC 320/C13 mains cable socket has to be connected

to an appropriate mains cable by a trained technician, respecting your local regulations. Refer to the “Installation, Operation, and Waste Disposal” chapter at the beginning of this manual. In case of 24 VDC operation, use an appropriate connection to the external DC supply unit or battery, equipped on one end with the attached 10-pole cable socket.

For DC operation it is mandatory that a UL approved, external fuse is connected in series with one of the supply lines (T 10 A H 250 V UL/CSA).

For pin assignment of the 24 VDC connector please refer to chapter 14.1.

Please check your DC supply cable for correct polarity before connecting it to the console.

Earthing: This equipment must be earthed, due to the mains input filter network be-

ing connected to the mains earth. Also in case of DC operation, earthing of the unit is mandatory.

Some consideration should be given to the earthing arrangement of the system, at the center of which is the console. The console chassis is earthed to the mains earth via the power supply and/or the dedicated earth connection bolt. Ground loops may occur where signal processing equipment, patched to the console, has its signal earth commoned to the equipment chassis.

2.2.3 Adjustments, Repair

Danger: All internal adjustments as well as repair work on this product must be

performed by trained technicians!

Replacing the Supply Unit: The primary fuse is located within the power supply unit and cannot be

changed. In case of failure, the complete supply unit must be replaced. Please contact your nearest Studer representative.

Fuse for DC Supply: For DC operation there is a second fuse located on the PSU Sub Board

(please refer to chapter 14.1 for details). In case of failure, this fuse must be replaced by a spare fuse of exactly the same type and value.

2.2.4 PC-Card

A standard OnAir 1000 mixing console is equipped with a PC-Card socket. Using the industry-standard SRAM PC-cards, the user can save important console information on a card. This information can then be used to restore the console to the same state at a later moment. Since the information stored on the card is DOS compatible, it is easily transferred to an IBMcompatible PC for data storage and backup.

Note: Although it is possible to format an SRAM card in a PC, the card must be

re-formatted in the OnAir 1000; therefore, the write protect tab must be set to OFF when the card is used in the mixing console for the first time. It is also possible for new software releases to be downloaded from an SRAM PC-card. This feature is only available for users in possession of the correct files. For more information on this subject, refer to chapter 12. The mixing console PC-card support is restricted to 5 V, Type 1, SRAM memory cards with capacities of 64 kbytes to 32 Mbytes. Hot-swapping is supported, too.
