3 Applications
The stereo mixer with integrated audio player
and Bluetooth receiver is suited for profes-
sional or private DJ applications as well as for
a PA system . The mixer is equipped with four
stereo input channels and a DJ microphone
channel . Headphones may be connected for
prefader listening to the input signals or to
the sum signal .
The mixer can be placed as desired or
may be installed in a rack (482 mm / 19") . Rack
installation requires a height of 2 RS (rack
spaces) = 89 mm .

The unit is generally approved for operation
in EU and EFTA countries; it is licence-free
and requires no registration.

4 Connecting Units

To avoid interfering noise, switch off the mixer
or turn back the following controls to mini-
mum prior to connecting / disconnecting:
— BOOTH (7)
— MASTER (9)
— PFL (18)
1) Connect the audio sources to the appro-
priate input jacks (28):
– jacks LINE and AUX to connect units with
line level (e . g . CD player, radio)
– jacks PHONO to connect turntables with
magnetic system
– jacks MIC to connect microphones
A maximum of three audio sources can be
connected to each input channel . Use the
appropriate input selector switches (6) to
switch between audio sources .
2) Connect a DJ microphone to the jack DJ
MIC (11) on the front panel .
3) Connect the amplifier for PA applications
to the XLR jacks MASTER (25) or to the
RCA jacks MASTER (26) . The two jack pairs
may be used simultaneously, e . g . for two
amplifiers .
4) Connect a monitor system located in a
separate control room to the jacks BOOTH
(24) . Use the control BOOTH (7) to adjust
the volume separately .
5) For audio recordings, connect a recorder
to the output jacks REC (27) . The recording
level is irrespective of the position of the
control MASTER (9) .
6) Use headphones for prefader listening to
the signals of the individual input channels
and to the sum signal [i . e . the signals can
also be monitored when the appropriate
channel fader (5) is completely closed or
the control MASTER (9) is turned back to
minimum] . Connect the headphones (min-
imum impedance: 8 Ω) to the jack
7) Use the mains cable provided to connect
the mains jack (22) of the mixer to a mains
socket (230 V/ 50 Hz) .

5 Operation

CAUTION Never adjust the audio system
and the headphones to a very
high volume . Permanent high
volumes may damage your
hearing! 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 increase a high volume after
getting used to it .
5.1 Switching on and off
To prevent switching noise and excessive
volume, set the following output controls
to minimum prior to setting the mixer into
operation:
— BOOTH (7)
— MASTER (9)
— PFL (18)
Use the POWER switch (21) to switch the
mixer on and off . When the mixer is switched
on, the LED indicator above the POWER
switch will light up .
5.2 Level control of the
input channels
The following steps merely serve as an aid;
other procedures are possible .
1) First, make the following basic adjust-
ments:
a) In all input channels, set the control
GAIN (4) and the tone controls HIGH
and LOW (14) to mid-position and com-
pletely close the channel faders (5) .
b) Turn back the control LEVEL (12) to
minimum .
c) To deactivate the crossfading function,
set the two sliding switches (16) for the
crossfader to position 0 .
d) Set the control BALANCE (20) to mid-
position .
2) To make sure that the input signal can be
indicated ahead of the level indicators (8),
turn up the control MASTER (9) to approx-
imately ⁄ of its maximum .

3) Advance the channel fader of the first
channel used to approximately
maximum (position number 7 of the
fader), use the input selector switch (6) to
select the signal source and then feed an
audio signal to the channel (e . g . piece of
music, microphone announcement) .
For channel CH 1, the audio player or
the Bluetooth receiver can be selected as a
signal source; please refer to chapters 5 .5
and 5 .6 for more information on how to
operate the audio player and the Bluetooth
receiver . Set the input selector switch of
channel CH 1 to the position MP3 .
4) Observe the level indicators for an opti-
mum adjustment of the input amplifica-
tion: Adjust the control GAIN so that a
level of approximately 0 dB is indicated for
music peaks .
(19) .
5) Adjust the sound, using the tone controls
HIGH for high frequencies and LOW for
low frequencies . Check the level of the
channel and, if necessary, use the control
GAIN to readjust the input amplification .
6) Close the channel fader . Repeat this pro-
cedure for all the other input channels .
5.3 Mixing audio sources
Crossfading between two
channels
1) After level control of the input channels
has been completed, the channel faders
(5) can be used to mix the signals of the
input channels or to fade them in and out .
Always completely close the faders of the
channels that are not used .
2) Use the control MASTER (9) to adjust the
definite volume of the sum signal, and use
the control BALANCE (20) to adjust the
stereo balance . The signal level is indicated
by the level indicators (8) . Usually, the opti-
mum level is obtained at 0 dB . However, if
the output level of the mixer is too high or
too low for the amplifier connected, atten-
uate or boost the sum signal accordingly,
making sure that no distortions occur .
Use the control BOOTH (7) to sepa-
rately adjust the volume of a monitor sys-
tem that has been connected to the jacks
BOOTH (24) .
3) For an announcement via a microphone
connected to the jack DJ MIC (11), use the
control LEVEL (12) to adjust the volume,
and the tone controls HIGH and LOW (13)
to adjust the sound . If it is necessary to im-
prove the audibility of the announcement,
use the faders to attenuate the volume of
the input channels CH 1 to 4 .
4) The crossfader (15) allows crossfading
be tween two channels . Use the sliding
switches (16) to select the two channels
that are to be crossfaded .
5.4 Prefader listening to the channels
CH 1 – 4 and to the sum signal
The input channels CH 1 – 4 can be separately
monitored via headphones even when the
corresponding channel fader (5) is closed .
Thus, it is possible to choose the next title
to be played, for example . In addition, the
sum signal can be monitored even when the
⁄ of its
2
3
control MASTER (9) has been set to minimum .
1) For prefader listening to an input channel,
press the appropriate button CH 1 – 4 (17),
or for monitoring the sum signal, press the
button MASTER .
2) Use the control PFL (18) to adjust the head-
phone volume .
