ProMix 4 Installation and Operation Manual
OPERATION
MIX-MINUS OUTPUT
The console’s Mix-Minus output (11) is a monaural mix of all sources assigned to
the Program bus, except for Line channel # 3. This input should be used for the
“Receive” (caller) audio from a telephone hybrid. The Mix-Minus output is therefore
the same as the Program mix, minus the caller. This Mix-Minus signal is normally
fed back into the hybrid’s “Send” input.
USING A TELEPHONE HYBRID
If the console will be interfaced to a telephone hybrid (for broadcasting telephone
calls), the Receive (“caller”) output of the hybrid should be fed into Channel 3’s line
input. The Mix Minus output of the console contains ALL line sources mixed to the
Program buss, except for Channel 3. The “program-minus-caller” Mix Minus out-
put is normally fed back to the hybrid’s send input. The caller will therefore be able
to hear all program sources mixed on the Program bus, minus him (caller). Be sure
to depress the front panel “Mix Minus” push button (12) to enable this feature.
