Operation - IMG STAGELINE MPX-1/VCA Bedienungsanleitung

If the mixer and the power supply unit are to be put
GB
out of operation definitively, take them to a local
recycling plant for a disposal which is not harmful to
the environment.
4 Connection
Switch off the mixer prior to connecting any units or to
changing any existing connections.
1) Connect the stereo audio sources to the corre-
sponding input jacks of channels 1 and 2 (white
jack LEFT; red jack RIGHT):
- units with line level output (e. g. minidisk recorder,
CD player, tape deck) to the jacks LINE (20);
- turntables with magnetic system to the jacks
PHONO (21). Connect the ground of the turn-
tables to the clamping screw GND (22).
2) Connect a DJ microphone to the left 6.3 mm jack
(14) on the face of the unit.
3) Connect the amplifier to the output AMP (19).
4) For sound recordings, connect the sound recorder
to the output REC (18).
5) Channels 1 and 2 can be monitored via stereo
headphones (impedance ≥ 8 Ω) ahead of the faders
(9) [see chapter 5.5 "Prefader listening to the chan-
nels"]. Connect the headphones to the right-hand
6.3 mm jack (16) on the face of the unit.
6) Finally connect the supplied plug-in power supply
unit to the low-voltage jack (17) and then to a mains
socket (230 V~/50 Hz).

5 Operation

Prior to switching on, set the channel faders (9) and
the microphone level control (1) to minimum to prevent
switching noise. Then switch on the mixer with the
switch POWER (2). With the mixer switched on, the
power LED above the switch lights up. Finally switch
on the connected units.
After operation, switch off the mixer with the switch
POWER. If the power supply unit is not used for a lon-
ger period, disconnect it from the mains socket as it
has a low power consumption even with the mixer
switched off.
5.1 Basic adjustment of channels 1 and 2
For optimum level control of channels 1 and 2, set the
gain controls (5) and the tone controls (6 and 7) to mid-
position first, and make the following basic adjustments
for the crossfader (11): Set the control C.F. CURVE (15)
to the left stop to position "N". Shift the reverse switch
(12) to the left position; the reverse LED above the
switch will show green. (Detailed information concerning
the crossfader adjustments can be found in chapter 5.3.)
1) Select the corresponding signal sources for chan-
nels 1 and 2 with the input selector switches (4):
either the unit at the input LINE (20) of the channel
or the unit at the input PHONO (21).
2) For level control of channel 1, move the crossfader
(11) to the left stop.
3) Feed an audio signal (test signal or music piece) to
channel 1 and control the channel level by means of
8
the VU-meter (3) with the fader (9) of channel 1.
Usually an optimum level control is obtained if the
VU-meter shows values in the 0 dB range at average
volume. However, if the output level is too high or too
low for the following unit, the channel signal must be
controlled to a corresponding lower or higher level.
4) After level adjustment, the fader should be set to
2
approx. / of its maximum. With the fader ad-
3
vanced very little or very far, the level must be
matched by regulating the input amplification: Turn
up or turn back the gain control (5) of the channel
accordingly (if required, the gain control can also
be set to either stop "MIN" or "MAX").
5) Adjust the desired sound with the treble control (6)
and the bass control (7): The high frequencies and
low frequencies can be corrected by ±15 dB max.
With the controls in mid-position, the frequency re-
sponse is not affected.
Note: Sound adjustments affect the level. There-
fore, after adjusting the sound, check the
channel level with the VU-meter and correct
it, if required.
6) Adjust the desired fader characteristic for channel 1
with the switch CURVE (8) of channel 1:
position "SMOOTH": smooth fade-in/fade-out
(normal adjustment)
slow and gradual increase/decrease of level
when moving the channel fader (9) over its entire
control range
position "FAST": hard fade-in/fade-out
fast and abrupt increase/decrease of level when
moving the channel fader (9) in the lower third of
its control range
position "FLAT": hard fade-in/fade-out
fast and abrupt increase/decrease of level when
moving the channel fader (9) in the upper third of
its control range
7) For level control of channel 2, move the crossfader
(11) to the right stop and follow the same adjusting
procedure as for channel 1.
5.2 Microphone adjustments
For level control of the DJ microphone connected to
the jack MIC (14), switch off all units to play on chan-
nels 1 and 2 or set them to pause. Then adjust the
desired volume for the microphone with the control DJ
MIC (1) by means of the VU-meter (3).
5.3 Crossfading between channels 1 and 2
1) Control channels 1 and 2 to their optimum level
(see chapter 5.1).
2) Use the reverse switch (12) to assign channels 1
and 2 to the crossfader (11):
switch at the left position, reverse LED above the
switch shows green
left side of the crossfader: channel 1
right side of the crossfader: channel 2
switch at the right position, reverse LED above the
switch shows red
left side of the crossfader:
right side of the crossfader: channel 1
channel 2
