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.
A1 First Aid
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.

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).
ESD/Repair
III
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.

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-
Installation/Maintenance/ESD
IV
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
ESD/Repair
V
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 (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
VI
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. No warranty claims will be accepted for circuit boards that
have been damaged. Proper and improper SMD soldering joints are illustrated below.
F Disposal
Disposal of Packing Materials The packing materials have been selected with environmental and disposal
issues in mind. All packing material can be recycled. Recycling packing
saves raw materials and reduces the volume of waste.
If you need to dispose of the transport packing materials, please try to use
recyclable means.
Disposal of Used Equipment Used equipment contains valuable raw materials as well as materials that
must be disposed of professionally. Please return your used equipment via
an authorized specialist dealer or via the public waste disposal system, ensuring any material that can be recycled is.
Please take care that your used equipment cannot be abused. To avoid
abuse, delete sensitive data from any data storage media. After having disconnected your used equipment from the mains supply, make sure that the
mains connector and the mains cable are made useless.

Appendix
VIII
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
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
IX
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 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 INTRODUCTION
The Studer OnAir 500 is designed first and foremost as a broadcast radio
console, which can simply drop in to any existing setup with a minimum of
fuss. This might be as a replacement for older analog equipment, or integration into a totally digital environment. The instantly familiar “analog” control style of the Studer OnAir 500 ensures that users do not have to fight with
the technology in order to start using the powerful features on offer. The
added benefits of automation to the professional radio presenter are obvious
– simple single-key recall of a complete console state with effects, routing
and EQ all configured, according to the user’s preferences. Whether in a
studio or in an outside broadcast vehicle, the Studer OnAir 500 will offer the
user repeatable, detailed control over a powerful feature set, in a simple and
efficient manner.
All of this control would have been little use without the intuitive interface
incorporating the edit strip, which allows fast access to all audio parameters
on the console when used in conjunction with the EDIT key present on each
channel. The “Tap and Adjust” functionality of the Studer OnAir 500 provides even the first-time operator with a familiar channel strip and a meter
bridge equipped with bar graph meters.

1-2 Introduction Date printed:
30.07.04
Each channel has full access to the edit strip, which offers three-band EQ
with semi-parametric midrange equalization, variable high-pass filter and
two auxiliary sends, a digital trim control with a range of ±12 dB, and a pan/
balance control. Every channel has an assignable stereo dynamics processor
offering a choice of compression, limiting and gating facilities.
The on-board Lexicon™ effects processor can be accessed from any channel
by configuring either the AUX 1 or AUX 2 send to operate as an effects send.
Immediacy is critical in the broadcast environment and so it was important
to have controls on each channel, like input 2 switching. Also included are
advanced but simple-to-use functions, like how the channel ON keys or fader
movements can trigger remote equipment, and how the PFL key can activate
talkback to cleanfeeds if required. Comprehensive talkback facilities and
compatibility with existing systems ensure that the user is never out of touch
even during the most complex of outside broadcast links.
The built-in MIDI ports allow full backup and restore of console presets via
MIDI system-exclusive data transfers.

1.2 Feature Overview
Analog Inputs The Studer OnAir 500 offers four assignable mic/line inputs, using digitally
controlled mic pre-amps. Two mic/line Inputs have an analog insert point
using a stereo jack plug, and all have a gain range from 0 to +60 dB, with
switchable 48 V phantom power. Two stereo inputs are also available with a
gain range from 0 to +18 dB. For monitoring purposes, there are four external stereo inputs accessible via a 37-pin D-type connector, with a gain range
from 0 to +18 dB. All of the above inputs are electronically balanced and
feature 24 bit, 128 × oversampling A/D converters.
A further eight analog inputs can be achieved by connecting an external mic/
line input interface box to the TDIF port found on the rear of the Studer
OnAir 500.
Analog Outputs The Studer OnAir 500 offers an array of analog outputs. There are electroni-
cally balanced XLR outputs for the PROG and AUD mix buses, and unbalanced outputs for control room and studio monitors. Outputs for guest, studio, and control room headphones are supplied, with a duplicate control room
headphone socket located at the front.
Outputs for AUX buses 1 and 2, line/clean-feed buses 1 and 2, stereo PFL,
mono PFL and cue speaker are located on the 37 pin D-type connector.
A further eight analog outputs can be achieved by connecting an external
analog output interface box to the TDIF port found on the rear of the Studer
OnAir 500.
Digital Inputs Four dedicated AES/EBU inputs and one S/PDIF input for connecting CD,
MiniDisc and DAT units are provided on the rear of the Studer OnAir 500.
Additional digital inputs are accessed by an eight-channel TDIF connector.
With the exception of the TDIF inputs, all other digital inputs are equipped
with sample rate converters, simplifying the setup and eliminating the need
for all devices in the system to share a common wordclock. All digital inputs
can be routed freely to any channel in exactly the same way as the analog
inputs, and therefore have the same access to the edit strip (there are, however, limitations regarding the routing of the S/PDIF input - see chapter 4.2
for details).
A further four AES/EBU inputs (four stereo or eight mono) can be achieved
by connecting an AES/EBU input interface box to the TDIF port.
Digital Outputs There are two AES/EBU digital outputs provided on male XLR connectors,
and one S/PDIF output via an RCA/Cinch connector. The TDIF connector
also provides eight additional digital outputs that can be configured to output a variety of mono or stereo sources.
A further four AES/EBU outputs (four stereo or eight mono) can be achieved
by connecting an AES/EBU output interface box to the TDIF port.
Meters The Studer OnAir 500 has two stereo bargraph meters with a correlation
indicator above each of them. On the METER 1, three easily selected modes
show either the PROG or AUD output buses or the control room selection;
for METER 2, the same sources are menu-selectable. Metering can be specified at the time of ordering with either VU or PPM characteristics.

(cont.) Faders The 100 mm long-throw faders found on the Studer OnAir 500 work just as
you would expect on an analog console. The top end of the fader is calibrated
at 0 dB (unity gain). The master faders can be bypassed via the setup menu
so that both the PROG and AUD bus outputs are fixed at unity gain.
Edit Strip The edit strip places the main controls found on a conventional analog chan-
nel strip in one central, easy-to-access area. The edit strip has three-band
equalization, variable high-pass filter, two stereo-linkable AUX sends which
can be switched either pre- or post-channel fader, a digital gain control and a
pan/balance control together with PROG and AUD assignment keys.
Lexicon™ Effects Processor The Studer OnAir 500 features a built-in Lexicon™ stereo FX processor that
includes reverb, delay, chorus and flange effects and is fed from AUX sends
1 and 2. Customized effects can be stored in user libraries for later recall.
Stereo Dynamics Processors Each channel has a dynamics processor that is automatically configured de-
pending on the channel source, for either mono or stereo operation. It is positioned before the digital EQ and gain controls so that limiting can occur
during signal peaks.
Snapshot Presets Complete recall of all console settings can be stored in up to 128 preset
memory locations for recall.
Audio Quality All analog inputs and outputs on the Studer OnAir 500 have 24-bit 128 ×
oversampling A/D and D/A converters, ensuring wide dynamic range and
superb sonic performance.
Power Supply The OnAir 500 features both AC and DC supply. The internal supply unit is
auto-ranging, for supply voltages of 100...240 VAC, 50...60 Hz. A DC supply
input for connecting an external supply unit, a battery, or an uninterruptible
power supply (UPS) is provided as well. Both supply variants can be used
simultaneously for redundancy. A power alarm indicator on the front panel is
illuminated and warns the operator as soon as either one, the AC or DC supply fails while the other one keeps up running the console.

2 GENERAL
2.1 Utilization for the Purpose Intended
The OnAir 500 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.
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 (battery, external supply
unit, UPS) 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 3.15 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.
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).
OnAir 500 Digital Mixing Console
2-2 General Date printed:
02.08.04
Cleaning: Do not use any liquids to clean the exterior of the unit. A soft, dry cloth or
brush will usually do. Never use any solvent for cleaning any surface of your
unit!
For cleaning the display windows, 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!
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 3.15 A H 250 V UL/CSA).
For pin assignment of the 24 VDC connector please refer to chapter 12.2.5.
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 being
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 per-
formed by trained technicians!
Supply Unit Replacement: 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.

3.2 Channel Strip
Input Display [1] This four-character display normally indicates the currently active channel
input (the name of which can be edited, refer to chapter 4.12). If the channel’s
dynamics processor is active, it indicates compressor/limiter gain reduction
and gate activity instead (see chapter 6).
Status Window [2] The status window contains individual displays that give constant visual in-
formation on:
• Whether the input source is ANALOGUE or DIGITAL.
• Whether the channel is assigned to the PROGRAM or AUDITION out-
puts.
• Whether the AUX 1 or AUX 2 sends are active on the selected channel
(the legend will illuminate as soon as either of the AUX 1 or AUX 2 sends
are opened).
• Whether the channel has been configured as a CLEANFEED source.
• Whether the channel has been configured as the TALKBACK channel
• Whether the EQ IN button is active on the channel
• Whether the channel’s dynamics processor is active or not (DYN IN).
INPUT 2 [3] The INPUT 2 button indicates whether input 1 or input 2 is the current input
source for the channel. If the INPUT 2 button is dark, then input 1 is active. If
the INPUT 2 button is illuminated then input 2 is active.
Note: The REV TB1 (reverse talkback input) and the four external monitoring in-
puts (on the ANALOGUE I/O 37-pin D-type connector) cannot be used as
channel inputs.
SELECT [4] When the SELECT button is pressed, the edit strip will be assigned to the
selected channel. The SELECT button is also used in conjunction with some
of the setup menus, for fast configuration of console functions.
CUE [5] The CUE button routes the channel source to the CUE/PFL bus. This allows
the presenter to listen to any channel source before the fader is opened. The
CUE button can also be used together with the TALK button [34] to send
talkback, usually the presenter’s microphone, to a designated cleanfeed output. The CUE button can be latched by giving it a short press; alternatively it
can have a momentary action by holding it down.
OVL LED [6] The OVL LED indicates clips occurring in the digital domain.
Channel Fader [7] The channel fader is a high-quality, 100 mm fader with a logarithmic scale.
Any channel fader can be configured in the Assign Channels menu to start
external equipment and to trigger the timers (refer to chapters 4.17 and 9.2).
ON / OFF [8] The large ON and OFF buttons are used to switch the channel on and off.
They may also be configured for triggering external devices using the remote relay port (refer to chapter 4.17).
