Important for U. K. Customers!
The wires in this mains lead are coloured in
accord-ance 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 termi-
nals in your plug, proceed as follows:
1 . The wire which is coloured blue must be
connected to the terminal 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
definitively, take it to a local recycling
plant for a disposal which is not harm-
ful to the environment .

4 Connection of the Mixer

Prior to connecting units or changing existing
connections, switch off the mixer and all other
audio units or set all output signals to zero .

4.1 Inputs

1) Connect the audio sources to the corre-
sponding input jacks of the input channels
[mono inputs for the two microphone chan-
nels, stereo inputs for the channels CH 1 to
CH 4 (white jack = left channel, red jack =
right channel)]:
8
– a DJ microphone to the XLR jack (1) or to
the 6 .3 mm jack (41) of the MIC 1 channel;
– a further microphone to the XLR jack (2)
.
or to the 6 .3 mm jack (40) of the MIC 2
channel;
– units with line level output (e . g . CD player,
minidisk recorder, tape deck) to the CD or
LINE jacks (39);
– turntables with magnetic system to the
PHONO jacks (30) . The clamping screw
GND (31) can be used as common ground-
ing point: connect the grounding connec-
tion of the turntable to the clamping screw .
2) Unless the stereo input RETURN (37) is pro-
vided for the connection of an effect unit
(see chapter 4 .3), it can be used as additional
input for a line source . The signals of the unit
connected to these jacks are mixed with the
RETURN control (23) to the stereo master .

4.2 Outputs

1) Connect the amplifiers to the corresponding
output jacks:
– the master signal of master channel A is
avail able at the two stereo outputs (33);
either the balanced XLR output or the un-
balanced RCA output can be used .
– the master signal of master channel B is
avail able at stereo output B (34) .
2) If a monitor system is available, connect the
amplifier of the monitor system to the stereo
output BOOTH (35) .
3) For audio recordings, connect the record-
ing unit to the stereo output REC (36) . The
recording level is independent of the position
of the master faders (16 and 18) .
4) Via stereo headphones, the pre-fader levels
of microphone channel MIC 2 and stereo
channels CH 1 to CH 4 as well as the current
music program ahead of the master faders
can be monitored (see chapter 5 .6) . Connect
the headphones (minimum impedance 8 Ω)
to the jack (19) .

4.3 Connections for an effect unit

Via the stereo connections SEND (38) and
RETURN (37), it is possible to route signals of the
input channels out of the mixer, to feed them
through a connected effect unit (e . g . equalizer,
reverberation unit) and to feed them back to
the mixer again .
The effect send way is designed "pre-
fader", i . e . the channel signals are fed to the
effect way ahead of the channel faders (12) .
1) Connect the input of the effect unit to the
SEND jacks .
2) Connect the output of the effect unit to the
RETURN jacks .
4.4 Connections for the remote control
of CD players and turntables
CD players or turntables to be contact-con-
trolled, connected to channels CH 1 to CH 4,
can remotely be started via the mixer (fader
start) . For this purpose, connect the respective
control input of the con nected unit to the corre-
sponding 6 .3 mm jack START (29) of the mixer .

4.5 Console illumination and mains voltage

For the console illumination, a gooseneck lamp
(12 V/ 5 W max .) can be connected to the LAMP
jack (13), e . g . the lamp GNL-404 . The lamp is
switched on and off with the mixer .
Finally connect the plug of the mains cable
(32) to a mains socket (230 V 50 Hz) .

5 Operation

Prior to switching on, the master faders (16 and
18) and the monitor control BOOTH (15) should
be set to minimum to avoid switch-on noise .
Then switch on the mixer with the POWER
switch (14) . The LED next to the switch lights up
to indicate that the unit is ready for operation .
Then switch on the connected units .
CAUTION Never adjust the audio system
accustomed to high volumes which do not
seem to be that high after some time . There-
fore, do not further increase a high volume after
getting used to it .

5.1 Basic settings of the input channels

The following operating steps merely serve as
an aid; other procedures are also possible .
1) For an optimum level adjustment of the audio
sources connected to the input channels,
turn the GAIN controls (4) and the equalizer
controls (5 and 7) to mid-position first, and
set the C .F . ASSIGN switches (26 and 28)
to "X" (crossfading function switched off) .
2) For switching on the DJ microphone, press
the ON AIR button (9) [LED above the button
lights up] .
3) With the selector buttons (3) select the signal
sources connected to the channels CH 1 to
CH 4 .
4) With the two master faders, the total level
of all connected audio sources is adjusted
which is available at the master outputs:
master fader A (16) for the two master
outputs A (33), master fader B (18) for the
master output B (34) .
Set the control of the master channel
which is used for the basic setting of the
input channels to approx . ²⁄ ³ of the maxi-
mum, e . g . to position 7 . Switch the stereo
VU meter (22) to the selected master channel
with the button (17):
button not pressed:
button pressed:
5) To control a channel, set the faders (12) of
the remaining channels to minimum and
feed the audio signals (test signals or music
pieces) to the respective input channel .
6) By means of the stereo VU meter, control the
level of the channel with its channel fader .
An optimum level control is obtained if level
values in the 0 dB range are shown at high
volume . If the red LEDs of the VU meter light
up, the channel is overloaded . After the level
adjustment, the fader should be in approx .
²⁄ ³ of the maximum position so that there is
sufficient control range for fading in and out .
Start
If the fader has been advanced slightly
Stop/Pause
or very far, the level must be matched by
adjusting the input amplification: turn up
or the headphones to a very
high volume . Permanent high
volumes may damage your
hearing! The human ear will get
master channel A
master channel B
