paging mic (ch 2)
logic inputs set for
inverted operation.
Inverted operation of the
'paging mic' logic inputs
allows the microphone
push-to-talk switches
to un-mute the mic signal
at the appropriate outputs.
Non-inverted operation of
the 'music' logic inputs
assigns music to all outputs.
Music assign switches may
be added, which will mute
music at specific outputs
(music assign switches
require diode isolation).
