2 Safety Notes
The unit corresponds to all relevant directives of
the EU and is therefore marked with
WARNING The unit is supplied with hazard-
ous mains voltage. Leave servic ing
to skilled personnel only. In expert
handling may result in electric
shock.
•
The unit is suitable for indoor use only. Protect
it against dripping water and splash water, high
air humidity and heat (admissible ambient tem-
perature range 0 – 40 °C).
•
Do not place any vessels filled with liquid, e. g.
drinking glasses, on the unit.
•
Do not set the unit into operation and immedi-
ately disconnect the mains plug from the mains
socket if
1. there is visible damage to the unit or to the
mains cable,
2. a defect might have occurred after a drop or
similar accident,
3. malfunctions occur.
The unit must in any case be repaired by skilled
personnel.
•
A damaged mains cable must only be replaced
by skilled personnel.
•
Never pull the mains cable to disconnect the
mains plug from the mains socket, always seize
the plug.
•
For cleaning only use a dry, soft cloth; never use
chemicals or water.
•

Important for UK Customers!
The wires in this mains lead are coloured in ac-
cordance with the following code:
blue = neutral
brown = live
As the colours of the wires in the mains lead
of this appliance may not correspond with the
coloured markings identifying the terminals in
your plug, proceed as follows:
1. The wire which is coloured blue must be con-
nected to the terminal in the plug which is
marked with the letter N or coloured black.
2. The wire which is coloured brown must be
connected to the terminal which is marked
with the letter L or coloured red.
If the unit is to be put out of operation
de finitively, take it to a local recycling
plant for a disposal which is not harmful
to the environment.
3 Applications
This 4-channel mixer is suitable for universal appli-
cations. It allows to connect up to two audio units
with line output level (e. g. CD or DVD player, tape
deck) and up to two microphones and to mix their
signals to two master outputs. The master outputs
can be muted via an optional remote switch. The
mixer is also equipped with an additional record-
ing output and an adjustable headphone output.
With the two supplied mounting brackets
[(10) in fig. 2], the mixer can be installed into a
rack for units with a width of 482 mm (19"): Fix the
brackets at the right side and left side at the front
with three screws respectively. In the rack, a height
of 1 rack space = 44.45 mm is required. However,
the mixer can also be used without brackets as a
table top unit.
4 Making the Connections
Prior to connecting any units or changing existing
connections, switch off the mixer and the units
used.
1) Connect the audio sources to the input channels:
– microphones (balanced or unbalanced) to the
6.3 mm jacks MIC 1 and 2 (16),
.
– stereo units with line output level (e. g. CD or
DVD player, tape deck, DAT recorder, tuner)
to the RCA jacks LINE 1 and 2 (15).
Instead of the rear input LINE 2, the front
input LINE INPUT 2 (7) can be used.
2) Connect the power amplifiers or other following
units with line input level (e. g. second mixer,
effect unit) to the RCA jacks OUTPUT (13).
Via a switch or momentary pushbutton con-
nected to the screw terminals MUTE (11), the
outputs OUTPUT can be muted, e. g. when the
sound is no longer to be reproduced via the
PA system but only via headphones. For better
handling, the terminals can be removed from
the unit and be replaced again after screwing
the two switch lines.
3) A recorder can be connected to the RCA jacks
REC (14). Adjustments of the controls LEVEL (12)
do not affect the recording signal.
4) Stereo headphones (minimum impedance 32 Ω)
for monitoring the output signal may be con-
nected to the 6.3 mm jack
ter 5, operating step 6).
5) Finally connect the mains plug of the connection
cable (17) to a socket (230 V/ 50 Hz).

5 Operation

CAUTION
Your ear will get accustomed to high volumes
which do not seem to be that high any more
after some time. Therefore, do not further in-
crease a high volume after getting used to it.
1) As a basic adjustment, turn the controls LEVEL
(12) for the outputs OUTPUT (13) to the left
stop, using a small screwdriver.
2) Switch on the mixer with the on / off switch
POWER (4), the POWER LED (3) lights up. Switch
on the connected units.
3) Mix the input signals with the volume controls
of the input channels [(1) for the microphone
channels MIC 1 and MIC 2, (2) for the stereo
channels LINE 1 and LINE 2] or fade them in and
out as required. Always turn the controls of the
channels not used to the left stop "0".
4) The channels MIC 1 and MIC 2 are each equipped
with a 3-way equalizer (5), the channels LINE 1
and LINE 2 have a common 2-way equalizer (6).
The frequency ranges (LOW, MID, HIGH) can
be boosted or attenuated by ±12 dB as a maxi-
mum with the corresponding controls.
5) If the level of an output OUT (13) is too low for
the following unit, it can be boosted with the
control LEVEL (12) located next to it: Turn up
the control correspondingly.
6) Turn up the volume control (9) for the head-
phone output
phones, the output signal can be heard which is
not affected by the controls LEVEL (12).
