voltage. Leave servicing to
skilled personnel only. Inexpert
handling may result in electric
shock.
•
The unit is suitable for indoor use only. Pro
tect it against dripping water and splash
water, high air humidity and heat (admissible ambient temperature range 0 – 40 °C).
•
Do not place any vessel filled with liquid on
the unit, e. g. a drinking glass.
•
Immediately disconnect the plug from the
mains socket
1.
if the unit or the mains cable is visibly
damaged,
2.
if a defect might have occurred after the
unit was dropped or suffered a similar
accident,
3. if malfunctions occur.
In any case the unit must be repaired by
skilled personnel.
•
Never pull the mains cable to disconnect
the mains plug from the socket, always
seize the plug.
•
For cleaning only use a dry, soft cloth; never
use chemicals or water.
•
No guarantee claims for the unit and no
liability for any resulting personal damage
or material damage will be accepted if the
unit is used for other purposes than originally intended, if it is not correctly connected or operated, or if it is not repaired
in an expert way.
If the unit is to be put out of operation definitively, take it to a local
recycling plant for a disposal which
is not harmful to the environment.
3 Applications
The 3-channel mixer MPX-30DMP is designed
for any private or professional DJ applications.
It offers connections for units with line level
(e. g. CD player), turntables and a DJ microphone. The integrated MP3 player is an additional audio source: It will replay MP3 audio
files from USB storage media (e. g. USB flash
drives) and SD / SDHC cards (32 GB max.). Pre
fader listening to all audio sources via headphones is available.
Set up the mixer on its own or install it
into a control console.
4 Connection
Prior to making or changing any connections,
switch off the mixer and the units to be connected.
1) Connect the stereo audio sources to the
corresponding RCA input jacks (26) of the
channels CH 1 to CH 3 (white jack L = left
channel; red jack R = right channel):
Connect units with line level output
(e. g. CD player, tape deck, radio) to
– the input LINE 1/ PHONO 1 of channel
CH 1; the button (27) next to this input
must be disengaged
– the input LINE 2 of channel CH 2
– the input LINE 3 of channel CH 3
Connect turntables with magnetic sys-
tem to
– the input LINE 1 / PHONO 1 of channel
CH 1; the button (27) next to this input
must be engaged
– the input PHONO 2 of channel CH 2
– the input PHONO 3 of channel CH 3
If there is a separate ground cable at the
connection cable of the turntable, connect this ground cable to a clamp screw
GND (28).
2)
Connect a microphone via XLR plug or
6.3 mm plug to the balanced jack MIC (2).
3)
To connect amplifiers, several stereo outputs are available:
– Balanced XLR output R BAL. / L BAL. and
unbalanced RCA output MASTER (23):
Connect the main amplifier for PA ap-
plications to one of these outputs. The
XLR output should be preferred: The
balanced signal transmission offers a
higher protection against interference
which may occur particularly with long
connection cables.
The XLR output and the RCA output can
also be used at the same time to connect
two amplifiers.
– Output BOOTH (24), e. g. to connect an
amplifier for a monitoring system or for
PA applications in adjoining rooms.
4)
For audio recordings, connect the re-
corder to the stereo output REC (25).
The recording level is independent of the
position of the output controls MASTER
(13) and BOOTH (15).
5)
For prefader listening to the input channels
or for monitoring the sum signal ahead of
the output controls MASTER and BOOTH,
connect headphones (minimum impedance: 8 Ω) via 6.3 mm plug to the stereo
output (19).
6) Connect the mains cable provided to the
mains jack (21) first, and then connect it
to a mains socket (230 V/ 50 Hz).
5 Operation of the Mixer
Prior to switching on, set the output controls
MASTER (13) and BOOTH (15) to minimum to
prevent switching noise. To switch the mixer
on or off, use the POWER switch (20). When
the mixer has been switched on, the power
LED ON (11) lights up.
CAUTION Never adjust the audio system
and the headphones to a very
high volume. Permanent high
volumes may dam age your
hearing! Your ear will get
accustomed to high volumes
which do not seem to be that
high after some time. Therefore, do not further increase
a high volume after getting
used to it.
5.1 Mixing the audio sources
Crossfading between two channels
1) Use the toggle switches (5) to select the
desired audio source for each input channel:
CH 1 left position for the microphone at
the input MIC
right position for the unit at the
input LINE 1/ PHONO 1
CH 2 left position for the unit at the input
PHONO 2
centre position for the unit at the
input LINE 2
right position for the integrated
MP3 player
CH 3 left position for the unit at the input
PHONO 3
right position for the unit at the
input LINE 3
2) For level matching and sound correction
of the input signals, make the following
basic settings:
a) Set all channel faders (6) to minimum.
Set all gain controls (3), equalizer controls (4) and the crossfader (10) to
mid-position.
b)
If the LED above the button TALK (7)
lights up, disengage the button to
deactivate the talkover function.
c) Set the output control MASTER (13) to
approx. 2 ⁄ 3 of the maximum.
d) Feed an audio signal (e. g. music piece)
to the first input channel used and set
the corresponding fader (6) to approx.
2
⁄ 3 of the maximum.
e)
Use the control GAIN (3) of the channel
to control the level in such a way that
the 0 dB range of the VU meter (12)
lights up with music peaks. Adjust the
sound with the controls HIGH, MID and
LOW (4). If re quired, readjust the level
control with the control GAIN. After
gain and sound have been adjusted, set
the channel fader to minimum again.
f)
Repeat steps d) and e) for the other
input channels used.
Note: These operating steps are merely an aid; for
basic setting of the input channels, you may also
proceed differently.
