always the case the audio source for
the main output is, depending on its con-
figuration, either the output of the micro-
phone preamplifier or the output of the
compressor.
In summary, when selected for the correct
application, each of the system modes
can prove equally valuable. A thorough
study of how they impact the Model 233’s
operation can lead to many interesting
and powerful uses.

the talkback 1 button will allow talkback
audio to be sent to pin 2 of the intercom

Two modes are available:
• Disabled: In this mode the talkback 2
button will not allow talkback audio
to be sent to pin 3 of the intercom
interface.
• Talkback 2 to intercom interface pin 3:
In this mode the talkback 2 button will
control the routing of talkback audio to
pin 3 of the intercom interface. Pin 3 is

tem. For a single-channel Clear-Com
intercom system pin 3 is channel 1.
Conclusion
Once the eighteen switches have been set
to the desired Model 233’s operating con-
figuration, it may be time to reattach the
security plate. The exception is if the trim
pots associated with the line inputs and
intercom sidetone (null) need to be adjust-
ed. Details are provided later in this user
guide. The plate attaches using the four
rubber bumpers. They should be hand-
tightened only; no tools are to be used.
Two modes are available:
• Disabled: In this mode the talkback 1
button will not allow talkback audio
to be sent to pin 2 of the intercom
interface.
• Talkback 1 to intercom interface pin 2: In
this mode the talkback 1 button will con-
trol the routing of talkback audio to pin 2
of the intercom interface. Pin 2 is chan-
nel 1 of an RTS TW intercom system.
