Input Connectors - D&R DISCOM 4 Manual

GAIN
With the gain, the source level is adjusted to the internal mixer level.
The module has a three band equalizer to control the high and low frequencies individually in
bad acoustic environments.
Below the equalizer you will find the stereo CUE switch (Pre Fader Listening), this
switch gives you the possibility to check the signal before you mix it with your other signals .
The ON switch is used to start turntables and cassette decks as well as jingle machines.
Last control is the 100mm channel fader, this is the actual control to mix the signals.
Channel 3 to 4 have short travel faders to be able to do fast mixing.
CROSSFADER
Below the short travel faders you can find the crossfader enabling you to cross signals
between channels 3/4 and 5/6 without any level changes.
This is due to a sspecial curve

INPUT CONNECTORS

On the back of your Discom 4 you find six connectors, one has already been
discussed, that was the balanced or symmetrical microphone input, the other
two are the stereo line inputs.
On line B you can buy an optional available R.I.A.A. correction amp to be
able to mix turn tables. The level can be set by the gain control to match with
every available cartridge.
There is a stereo "CUE " switch on the front to cue the incoming signal.
Once you have done this, you can start the turntable with the ON switch.
These switches quickstart turntables through the remote jack at the back of
the mixer, if your turntable only needs a puls to start, ask your dealer to
remove the latching spring from the START switch to change it into a
momentary switch, so you can use it as a puls-startswitch.
*NEVER CONNECT THE MAINS TO THIS REMOTE-JACK*
Connections on the START connector can only be made with a maximum of 24 Volts by 500
mA.
Please contact your dealer in case of doubt.
