PCBEEP INPUT

Pin 19 (PCBEEP) is a mono, line level input intended for externally generated signal or warning

tones. It is routed directly to the record selector and all three output mixers, without an input

amplifier. The signal gain into each mixer can be independently controlled, with a separate mute bit

for each signal path.
