In some applications it may be desirable
for the output of the compressor circuit to
be routed to the main output. Appropriate
applications could include on-air broadcast
situations where nonprofessional talent is
present. Controlling the dynamic range of
the audio signals on the main output can
limit the chance of cable cross-talk and
equipment overload. Another typical ap-
plication where using the output of the
compressor would be appropriate is when
the Model 233’s system mode is selected
for production. In this case the main output
would be used as an additional talkback
output and dynamic range control would
be beneficial.
Sidetone Mode
Switch SW3-8 configures the way the
sidetone function operates.
Two modes are available:
• Main Button: In this mode the sidetone
function will only be active when the
main output is active.
• Main and Talkback Buttons: In this mode
the sidetone function will be active when-
ever the main, talkback 1, or talkback 2
outputs are active.
• Enabled: In this mode the talkback 1
button will operate normally. Whenever
the button is active the line-level output
and, if configured, the talkback to inter-
com pin 2 function, will be active.
Talkback 2 Button Function
Switch SW3-6 configures the overall
operation of the button associated with
talkback 2.

Two modes are available:
• Disabled: In this mode the talkback 2
button is disabled. The talkback 2 line-
level output and, if configured, talkback
to intercom pin 3 function, will never be
active. An exception is if the auxiliary
relay is configured to follow the status
of the talkback 2 button. In this case
the talkback 2 button will only control
the relay.
• Enabled: In this mode the talkback 2 but-
ton will operate normally. Whenever the
button is active the line-level output and,
if configured, the talkback to intercom
pin 3 function, will be active.
Main Output Source
Switch SW3-7 is used to select which audio
source is routed to the main output. The
choices are the output of the microphone
preamplifier or the output of the compres-
sor circuit. For most on-air applications
the output of the microphone preamplifier
is the desired source. This will provide the
most natural audio quality with the poten-
tial for a large amount of dynamic range.
