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.

Applications
The stereo disco mixer MPX-210 with four stereo input
channels and two mono microphone channels is suit-
able for various DJ applications for private or profes-
sional use.
The mixer may be used as a table top unit or may be
installed into a rack (482 mm/19"). The rack installation
requires 4 rack spaces (1 rack space = 44.5 mm).

Setting Into Operation
1) Connect the audio sources to the corresponding
input jacks:
- LINE resp. CD jacks (22) to connect units with
line level (e.g. tuner, CD player, tape recorder)
- PHONO jacks (23) to connect turntables with
magnet system
- MIC 1 and 2 jacks (24) to connect DJ mono
microphones
2) Press the selector buttons (2) for the channels
CH 1-CH 4 correspondingly: If the button is not
pressed, the LINE input is selected; if the button is
pressed, the PHONO input (for channels CH 1 and
CH 3) resp. the CD input (for channels CH 2 and
CH 4) is selected. If the button is pressed, the LED
above the button lights as an optical indication.
3) Connect the amplifier to the AMP output jacks (21).
4) Connect a recording unit to the REC output jacks
(20) if audio recordings are desired. The recording
level is independent of the setting of the master
controls (16).
5) A gooseneck lamp (12 V/5 W max.), e. g. GNL-200
of the range “img Stage Line”, may be connected to
the LAMP jack (6) for an optimum lighting of the
mixer. The lamp is switched on and off with the
mixer.
6) Connect the mains plug to a mains socket (230 V~/
50 Hz).
7) Prior to switching on the mixer, the master controls
(16) should be set to minimum to avoid loud switch-
ing noises. Then turn on the mixer with the POWER
switch (7). As an operating indication the red LED
above the switch lights.
8) Switch on the connected units.

Operation
Before taking the mixer into operation for the first time,
set all gain controls (4) and tone controls (1 and 3) as
well as the crossfader (12) to center position. The KILL
buttons (13) must not be pressed.
5.1 Mixing of the connected audio sources
1) The total volume of the connnected audio sources
can be adjusted with the master controls (16) -
LEFT for the left channel, RIGHT for the right chan-
nel. For the optimum level adjustment of the con-
nected units, set the master controls to approx.
2
/
3
of the maximum, e. g. position 7.
2) Adjust the volume of the input channels CH 1-CH 4
with the faders (15). The VU meter (5) displays the
stereo output level of the master output (21). At 0 dB
the mixer is at its rated maximum output. Overloads
are indicated via the VU meter by lighting of the red
LEDs.
The faders should be at approx.
2
/
3
of the maxi-
mum after the level adjustment so that there is suf-
ficient control range for fading in and out. If the
faders are almost at minimum or maximum position,
the levels have to be matched by adjusting the input
amplification: Turn up resp. turn back the GAIN con-
trols (4) of channels CH 1-CH 4 correspondingly.
3) To switch on the microphones at channels MIC 1
and MIC 2, press the ON AIR buttons (9) (the LEDs
above the buttons light). Adjust the desired input
amplification for the microphone signals with the
GAIN controls (4) of the microphone channels.
4) Adjust the desired sound characteristic for the out-
puts REC (20) and AMP (21) with the 3-way equal-
izer - controls (1) for the microphone channels,
controls (3) for both channel groups CH 1/CH 2 and
CH 3/CH 4: With the controls, the low (BASS),
medium (MID), and high (HIGH) frequencies can be
increased resp. decreased by 12 dB. The frequency
response is not affected if the controls are in center
position.
The high (HIGH button), medium (MID button),
and low (BASS button) frequencies of each channel
group can be suppressed via the KILL buttons (13):
If the button is pressed (LED of the button lights),
the corresponding frequency band is strongly de-
creased so that it will barely be heard in the sound.
To deactivate the kill function, press the correspond-
ing button again (LED of the button extinguishes).
5) Fading between both channel groups CH 1/CH 2
and CH 3/CH 4 is possible via the crossfader (12).
Both channel groups are fed to the outputs simulta-
neously if the crossfader is in center position.
For the short-time fading in of the channel group
which is faded out, press the corresponding TRIG-
GER button (14) of this channel group. As long as
this button is pressed, the channel group can be
heard.
5.2 Monitoring of the channels
Via the monitoring function it is possible to monitor the
input channels CH 1-CH 4 individually via head-
phones even if the corresponding fader (15) is at mini-
mum. By monitoring of an input channel the best
moment for fading in the corresponding audio source
can thus be selected.
It is also possible to monitor the stereo master sig-
nals via headphones. The level of the stereo master is
independent of the setting of the master controls (16).
1) Connect stereo headphones (impedance
≥
8
Ω
) to
the PHONES jack (8).
2) To monitor an input channel, press the correspond-
ing CUE button (11) (the LED above the button
