The TBA15 is a unique amplifier that permits loudspeakers
to be used as microphones to provide hands-free, two-way
conversations through the paging system*. In the idle state,
the TBA15 uses the attached speakers as microphones and
feeds this signal out to a telephone line. When the TBA15
senses a paging signal on the telephone line, it will switch
on its 15W amplifier and use the speakers conventionally.

TG4C
The TG4C is designed to produce four different types of tones for use as alarm or
announcement signals in paging systems. An audio signal can be routed through
the TG4C to allow easy installation in paging systems. During generation of the tones,
the routed audio will be suppressed.
