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.
