nel.
POWER switch. Switches the unit on and off. Make sure to switch the unit off when not in use.
PHANTOM POWER switch. This switch activates a 48V DC supply to the MIC inputs (11) for
powering condenser microphones. Phantom power shall remain switched off if only dynamic
microphones are used. The on/off status is indicated by a front-panel LED (21).
MAIN OUTPUT section. This contains a pair of XLR outputs which carry the balanced main mix
signal.
CONTROL ROOM OUTPUT. This is a pair of TRS connector carrying the same signal as the
front-panel headphones connector (27)
2TRK In/Out. This is a dual pair of unbalanced RCA stereo connectors for a tape or solid state
recorder in order to record from the main mix and replay into the main mix. The signal routing
can be determined by the relative front-panel switches (26).

AUX SEND. Every AUX bus (Monitor, EFX) has a balanced TRS output which carries the signal
composed from the channel AUX bus controls (16). Note that the Monitor AUX send is
pre-fader while the EFX (effects) AUX Send is post-fader.
AUX RETURN. This stereo TRS input is provided for connecting any mono or stereo line level
signal. Insert a mono source into the L jack to make sure the signal is fed into both L and R
main mix. The level of this input is adjusted by the respective RETURN control (24). Note that
this control also adjusts the level of the internal effects processor.
STEREO Line Inputs (for channel 9/10 and 11/12). These are two balanced 6.35mm TRS
connectors. Connect any line level stereo source here.
Insert a mono source into the L jack to
make sure the signal is fed into both the L and R channel mix.
LINE Input. This is a balanced 6.35mm TRS connector. Connect any line level source here. For
sources which require a high impedance input (like a guitar output), use a DI box inbetween the
source and the mixer’s line input. Do not use concurrently with the MIC input (11).
Microphone Input. This is a balanced female XLR connector. Connect any dynamic or
condenser capsule microphone here. If phantom power is required, it can be activated sepa-
rately via the rear panel switch (3). Do not use concurrently with the LINE input (10).
Insert Jack. This is an unbalanced 6.35mm TRS connector, with tip and ring carrying the send
and return signal of the insert path at line level. Use a Y TRS cable (insert cable) to insert an
external signal processor here.

MONO INPUT section (channels 1-8). These inputs channels can accept mono line input
signals to be connected to the rear-side TRS jacks (10) or mono microphone signals to be
connected to the rear-side XLR jacks (11). The mono input section has the same controls as
the stereo input section (B).
STEREO INPUT section (channels 9/10 and 11/12). These inputs channels can accept
stereo line input signals to be connected to the rear-side TRS jacks (9). The stereo input
section has the same controls as the mono input section (A).
GAIN controls. These controls allow to adjust the input sensitivity in a range of +10 to +60 dB
for the MIC input (11) and +10 to -40 dBu for the LINE input (10). The stting should be
adjusted so that the CLIP LED (14) only flashes occasionally
CLIP LED. Indicates an overload of the input channel. The gain (13) shall be adjusted to make
sure this only flahses occasionally.
EQUALIZER. This is a 2-band shelving equalizer with 80Hz (Low) and 12kHz (High) corner
frequencies and an adjustment range of +-15dB.
AUX buses. These two controls allow to create an independent signal mix from the master
output mix. The AUX1(M) bus is pre-fader and allows a mix independent from the channel
fader settings, useful for monitor applications. The resulting AUX1(M) signal can be picked up
at the rear-panel AUX SEND (M) jack (7). The AUX2(FX) bus is post fader and the levels
depend on the channel fader settings, which is useful for effects applications. The resulting
AUX2(FX) signal can be picked up at the rear-panel AUX SEND (FX) jack (7). Note that this
signal is also fed to the internal effects processor.
BALANCE/PAN control. Allows to set the balance between the left and right main signals. For
channels 1-8, the PAN controls determine the allocation of the mono inputs to the left and
right main outputs; for channels 9/19 and 11/12, the BALANCE controls determine the
balance beween the left and right main signal portions.
CHANNEL FADERS. These 60mm sliding controls determine the level of the respective chan-
nel in the master mix.
AUX Input for channel 9/10. This is a 3.5mm stereo TRS (unbalanced) input, suitable for the
connection of e.g. MP3 players. This AUX input is automatically overriding any other source
connected to this channel once a connector is inserted.
POWER LED. Indicates whether the unit is switched on or off.
PHANTOM POWER LED. Indicates whether the rear-side PHATOM POWER switch (3) is
enabled.
LEVEL Meter. Indicates the main output level at connectors (4) in 4 steps: -20dB (lower white),
0dB (upper white), +6dB (lower red), Clip (upper red).
MAIN FADER. This 60mm sliding control determines the output level.
AUX RETURN volume control. Sets the volume of the signal fed into the rear-side AUX
RETURN jacks (8).
AUX RTN SOLO. Assigns the AUX RETURN signal exclusively to the headphones/control room
outputs (5, 27).

Operation
A. Connections
For connecting this unit to AC mains, please note:
Check whether the AC mains voltage and frequency is the same as this product is specified for (see
rear panel of product). Whenever the specified voltage or your AC plug should not match the local
conditions, do NOT plug the AC cord into the wall outlet and contact you dealer immediately.
Do not operate this unit without the line cord earth ground connected. To do so may increase the
risk of electric shock and increase line cord conducted emissions.
For making audio signal connections, always remember that good and reliable connections are a
basic requirement for good sound and reliable operation. Bad soldering of cables can result in inter-
mittent audio signals or temporarily lost ground connections, hence always use good cables. In case
of doubt about making proper connections, please see check the standard pin assignments required
for proper operation in the following section of this manual.
B. Powering up
Following a proper power-up sequence protects your equipment – specifically speakers – and your
ears. Follow the below procedure:
Turn down all output volume controls of any equipment in your audio system.
Switch on your audio sources first (Tuners, CD Players, PC’s with soundcards, Tapedecks, etc.)
Switch on the audio mixer
Switch on any audio processor between the mixer and the amplifier(s) [if any].
Switch on the amplifier(s).
Turn up the audio level on your sources if such controls are provided.
Set the audio output of your mixer to a low level.
Set the audio output of any audio processor between the mixer and the amplifier(s) to a medium
level [if any such processors].
Turn up the volume controls of your amplifier(s) slowly.
Make adjustments to all volume settings as needed.
For switching off, follow the inverse sequence – always switch off your amplifier(s) first, then any
processors between mixer and amplifier(s), then the mixer, then the sources.
C. Use
Apart from using good equipment, good sound comes from using it correctly. Level setting mistakes
are one of the common reasons why even good equipment may not perform as desired. For setting
levels, please be reminded that two guidelines need to be followed:
Avoid distortion by leaving some headroom. Never overrun any audio-equipment’s inputs. Level
meters and displays allow you to make sure that signals do not enter critical levels.
Avoid unnecessary amplification by using as little attenuation as possible. For example, if you turn
down the input gain of a mixer to minimum, and then increase the main output of the mixer to maxi
mum to drive your amplifier properly, you will create unnecessary noise, as you first dispose of some
already existing signal level, and then later apply amplification (tainted with noise) to make it up.
Obviously, these two requirements are marking a levelling window that the operator must match to
achieve a good sound with as little distortion and noise as possible.
WARNING - HEALTH RISK
Excessive volume levels on headphones or other sound systems may cause hearing
damage. Always turn the volume control to minimum when you switch the unit on, and
avoid prolonged exposure to sound pressure levels exceeding 90dB.

Maintenance and warranty
While we have chosen the best components to make this product as rugged and reliable as possible,
some parts in audio products (potentiometers, faders, switches) are subject to wear which is a
matter of operation cycles, and not of time. While providing a full time-based warranty according to
the country’s of purchase requirements on the function of the electronic circuitry, we hence have to
limit the warranty on such electro-mechanical parts to 90 days from the date of purchase.
In many cases, malfunction of electro-mechanical parts occurs due to dust contamination, which may
require cleaning of such parts. As the inside of such parts is not accessible, a common practice is to
use cleaning fluids in the shape of sprays. Please be reminded that many of such fluids contain chemi-
cals which may wash away the dust but at the same time corrode or damage contact surface and
may cause cosmetic damage to other parts. We hence explicitly exclude any claims for exchange of
damaged part due to mechanical or chemical impact.
