Relay Mode
Switches SW4-5 and SW4-6 configure the
operating mode of the auxiliary relay.
main output will mute whenever a talk-
back function is active. The LED indicators
associated with the main output will light
accordingly. The on-air mode should be
selected for all on-air broadcast applica-
tions. It’s imperative that the main output
be muted whenever on-air talent is using
one of the talkback functions to communi-
cate with production personnel.
The stadium announce mode is very simi-
lar to the on-air mode with one important
addition. Whenever the main output is
active the external sources assigned to the
left and right headphone outputs will mute.
This ensures that an announcer won’t be
distracted at an inopportune time by audio
signals arriving from the line inputs or
intercom interfaces. It’s important to note
that the stadium announce mode will not
impact the headphone sidetone function.
When configured for the production
mode, the main output is never muted
in response to a talkback function being
active. The main output will be controlled
only by the main output pushbutton. This
mode allows the main output to be used,
for example, as an additional talkback
output. In this way, the main output and
talkback output functions can be used
independently with neither impacting the
other. This also allows all three buttons to
be used simultaneously. Note that as is
Figure 19. Auxiliary relay control mode settings
Four modes are available:
• Relay disabled: In this mode the relay is
disabled and will never change state.
• Follows main output status: In this mode
the relay will follow the state of the main
output. Specifically, the relay will change
state (energize) whenever the main out-
put is active.
• Follows talkback 1 button status: In this
mode the relay will follow the state of the
talkback 1 button. Specifically, the relay
will change state (energize) whenever
the button is active.
• Follows talkback 2 button status: In this
mode the relay will follow the state of the
talkback 2 button. Specifically, the relay
will change (energize) state whenever
the button is active.
System Mode
Switches SW4-7 and SW4-8 are used
to configure the overall operating mode
of the Model 233. Understanding how
the three modes impact overall system
operation will ensure that correct opera-
tion and maximum usability will occur.
When selected to the on-air mode, the
