The stereo mixer with four stereo input channels and
two mono microphone channels is suitable for any
desired DJ applications for professional or private use
as well as for PA system applications.
The mixer can be used as a table top unit or be
installed into a rack (482 mm/19"). For the rack instal-
lation two rack spaces = 89 mm are necessary.

4 Setting into Operation

1) Connect the audio sources to the corresponding
input jacks:
– LINE A, LINE B, CD, or LINE (20) to connect
units with line level (e. g. tuner, CD player, cas-
sette recorder);
– PHONO (21) to connect record players with
magnetic system;
– MIC 1 resp. MIC 2 (9) to connect mono micro-
phones.
2) Set the input selector switches (3) for the channels
CH 1 – CH 4 to the corresponding position.
3) Connect the amplifier to the output jacks AMP (19).
4) For possible audio recordings connect a recording
unit to the output jacks REC (18). The recording
level is independent of the position of the MASTER
control (13).
5) Plug the mains plug into the mains socket (230 V~/
50 Hz).
6) Before switching on the mixer the MASTER control
(13) should be set to minimum position to avoid a
strong inrush noise. Then switch on the mixer with
the switch POWER (7). The LED (8) above the
switch lights to show that the mixer is ready for op-
eration.
7) Switch on the units connected.
5 Operation
Prior to the first setting into operation set all equalizer
controls (10 and 14) to mid-position and the talkover
switch (4) to OFF. Set both C. F. ASSIGN switches (12)
to position "0" (fading function switched off).
Caution! Never adjust the audio system or the head-
phones to a very high volume. Permanent high vol-
umes may damage your hearing! The human ear will
get accustomed to high volumes which do not seem
to be that high after some time. Therefore, do not fur-
ther increase a high volume after getting used to it.
5.1 Mixing of the audio sources connected
1) With the MASTER fader (13) the total volume of all
audio sources connected can be adjusted. For opti-
mum level adjustment of the units connected set
the MASTER fader to approx.
position, e. g. position 7.

2) With the faders (2) adjust the level for the input
3) Adjust the desired tone for both outputs REC (18)
4) With the crossfader (11) it can be faded between
5.2 Monitoring of the channels
By the monitoring function it is possible to monitor
each individual input channel CH 1 – CH 4 as well as
the MASTER channel via headphones. The level of
the signal monitored is independent of the position of
the corresponding channel fader.
1) Connect stereo headphones (impedance ≥ 8 Ω) to
2) Press the corresponding button (6) of the channel.
3) Adjust the desired headphones level with the

two of the channels CH 1 – CH 4. For this select the
desired channels with the C. F. ASSIGN switches A
and B (12):
C. F. ASSIGN A: position 1, 2, or 3 to select the
channels CH 1, CH 2, or CH 3
C. F. ASSIGN B: position 2, 3, or 4 to select the
channels CH 2, CH 3, or CH 4
If the respective switch is in "0" position, no channel
is selected.
When moving the crossfader to the left, the
channel selected with the C. F. ASSIGN A switch is
faded in and when moving the fader to the right the
channel selected with the C. F. ASSIGN B switch. If
the fader is in mid-position, both channels are
passed to the outputs at the same time. To switch
off the fading function, set both C. F. ASSIGN
switches to "0" position.
