AC inlet and fuse holder. Use the supplied AC cord to connect the unit to AC mains. Make sure
voltage and frequency stated and set on the unit comply with your local AC supply. The fuse
can be accessed by the small drawer at the AC inlet. To change the fuse, unplug the AC cord
first, pull out the fuse drawer and replace the fuse ONLY with a fuse of SAME voltage and
rating. If the fuse blows again after replacement, hand over the unit to qualified service person-
nel.
MONO OUTPUTS (channel 5 to 6). These are mono outputs via balanced phone jacks (TRS).
MONO INPUTS (channel 5 to 6). These are mono inputs via balanced phone jacks (TRS).
MONO OUTPUTS (channel 1 to 4). These are the mono outputs via balanced XLR connectors.
MONO INPUTS (channel 1 to 4). These are mono inputs via balanced XLR connectors.
MAIN OUTPUTS. These are the main outputs, available as balanced XLR connectors. They
may be fed either by the left and right main inputs or by any of the six mono inputs (or a combi-
nation of both).
MAIN INPUTS. These are the main audio inputs, available as balanced XLR connectors. They
may feed the mono outputs of all channels which are operated in SPLIT mode.
MAIN INPUT LEVEL controls. These set the main input gain, before the signal reaches the
input bus. In SPLIT mode, the MAIN INPUT LEVEL control determines the common output level
for all mono outputs.
4-digit INPUT LEVEL meter. Shows the input level of the main input within a range from -24 to
+6 dB.
MAIN LINK switch. By pressing, the MAIN INPUT signal can be routed to the MAIN OUT. This
way it is possible to route a maximum of eight input channels to the main mix.
MAIN OUTPUT LEVEL control. This adjusts the output level applied to the main outputs. The
levels present at the six mono outputs are not affected. Summing the signal levels of several
mono channels can overload the main output stage. The MAIN OUTPUT LEVEL control is
therefore used to adjust the overall output level.
4-digit OUTPUT LEVEL meter. Shows the output level of the main input within a range from -24
to +6 dB.
SPLIT/MIX switch. Sets the respective channel to SPLITTER or MIXER mode.
LEVEL control. Determines the signal level of the individual channels. In SPLIT mode, the LEVEL
control sets the output level of the mono channels. In MIX mode, however, it controls the
amount of the mono channel’s input signal feeding into the main output section; at the same
time, the level of the mono channel can be determined, which—owing to the maximum gain of
+15 dB—allows for converting, e.g., home recording levels (-10 dBV) into studio levels (+4
dBu).

8-digit OUTPUT LEVEL meter. Shows the output level of each channel within a range from -24
to +18 dB.
BALANCE/PAN control. Allows to set the balance between the left and right main signals. In
SPLIT mode, the main input signal is routed to the mono output, with the BALANCE control
determining the balance beween the left and right main signal portions. In MIX mode, the
mono inputs are mixed and routed via the LEVEL control to the main outputs, with the PAN
controls determining the allocation of the mono inputs to the left and right main outputs
Power switch. Switches the unit on and off. Make sure to switch the unit off when not in use.

MAIN Section
Both main inputs connect via the MAIN INPUT LEVEL control with the input bus as well as with the
main outputs. The MAIN OUTPUT LEVEL control sets the output level of the signals which are
summed by the second bus (i.e., the output bus) and are subsequently routed to the main outputs.
SPLIT Mode
In SPLIT mode, the main input signal is sent via the BALANCE control to the output buffer amplifiers
of the mono channels, with the LEVEL control setting the output level of the respective channel. The
maximum gain is +15 dB.
MIX Mode
In MIX mode, the input signals of the mono channels are summed via the LEVEL and PAN controls
and are routed to the output bus. In this mode, the LEVEL control sets the amount of each channel at
the output bus, while the PAN control is responsible for the allocation of the input signal to the left and
right main outputs. Additionally, the input signal is routed to the respective mono outputs, i.e., the
circuit acts as a matching amplifier. The LEVEL control permits for a level compensation of up to +15
dB.

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.
