Quad Mic Preamp

(QMP-4)

Overview

The QMP-4 is a quad mono microphone preamplifier and is mounted

in the left side of the console meterbridge rear. Mic level sources are

wired to QMP-4 mic preamp inputs. QMP-4 output signals are then wired

to input pins of individual IN-75 input modules. IN-75 module A inputs

should be used if you need to have the mic activate control room or studio

muting. The IN-75 must be provided with an ADC-75 daughter card.

Phantom power is available at each input port; it may be selectively

activated by a dipswitch SW1 (the factory default is OFF).
