This semi-professional 5-channel mixerpanel has been designed for use in disco's, home  entertainement, mixrecordings, ao. and obtains a  separated  2 x 5-staged equalizer and   a   mastergain level control. The less-noise volume shafts  obtains a  very  reliable  mixing  of  the  several  inputs. The volume of each input channel can be set apart.

CONNECTIONS
At first the on/off switch (2) most be off. Set volume of amplifier and mixerpanel to "0".
Make the connections as follows:


 
 

MICROPHONES
The mixerpanel obtains two different microphone inputs; input (7) only for low-ohm  impedanced microphones;  volume of these has to been set by control (6) for microphone (1).
The backside connection can be used for high-  aswell  low-ohm  impedanced  microphones;  for setting up of the impedance, you'll use switch (8); the soundlevel of these, you can setup with control (20).

TURNTABLES
The mixerpanel can be used for crystal- aswell magneto-dynamic (MD) turntables:
To use the crystal types, switches (9), and (10) should be in the "CRY" position.
For connection of MD types, switches (9), (10) should be in "MAG" position.
Volume setting by controls (18) and (17).

TAPE
Connection for  two  tapes-  or  casettedecks  is  allowed;  set  switches  (11)  and / or  (12)  in  the  "TAPE"  position. Volume controls by (23) and (24).

TUNER
The mixerpanel has two tuner-connections. Using of these can be set by the switches (11) and/or (12) in the "TUNER" position. Volume controls by (23) and (24).

HEADPHONE / MONITOR
For the pre-listening connect a  stereo-headphone. to connection  (34).  The  dB Level  of  this  is controlled by volumecontrol (35). You can listen to the different output-signals with your headphone by controlling switches (37 - 42).
ATTENTION: Pre-listening of the microphones  is  microphone (1)   through  the  left-  and  the microphone (2) through the right headphone.

TALK-OVER
The talk-over switch (32) has been designed to make an announcement  through  the  microphone  during  a  music programme; use of this only by microphone (1).
In "NORMAL" position use switch (6) for controlling the dB level;
In "STANDBY" position, the microphone is switched off.;
In "TALKOVER" position the dB level of the music-programme is setting lower and the microphone amplified.

MASTER
With the master-gain switch (25) controls of all 5 channels can be done simultaniuosly.

VU-METERS
The output-signals are been controlled by 2 VU-Meters; don't let them go into the red area.

POWER OUTPUT
The power output control (13) normally has to been set to 0.775 V. In case using a  professional disco-amplifier, switch has to been set to 1.5 V. (See your manual).

PRESET
Above the shafting controls (20 - 25) are setup controls.  These  are  for  controlling  the  different dB Levels of identical machines in such a way, that both produce an equal volume. To setup these, set the corrsponding shafting-controls in the highest possible level.
