in its off (muted) state. When the talkback
function is no longer active the main output
will return to its previous latched on state.
When the talkback forces main button to
latch off mode is selected, and a talkback
function becomes active, the main output
will, if latched on, be placed in its off (mut-
ed) state and the latch condition forced off.
When the talkback function is no longer
active the main output will remain in the
latched off state.
The differences in how the main button
modes impact operation and user comfort
are relatively subtle. The nuances of both
modes should be considered before a final
selection is made. If possible, experiment-
ing with both modes in a test environment
might prove to be very helpful.
Auxiliary Relay Control Mode
Switch SW4-5 and SW4-6 configure the
operating mode of the auxiliary relay.
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 Modes
Switches SW4-7 and SW4-8 are used to
configure the overall operating mode of
the Model 230. Understanding how the four
modes impact overall system operation will
ensure that correct operation and maximum
usability will occur. When selected to one
of the two on-air modes, the main output
will mute whenever a talkback function is
active. The LED indicators associated with
the main output will light accordingly. An
on-air mode should be selected for all on-
air broadcast applications. It’s imperative
that the main output be muted whenever
on-air talent is using one of the talkback
functions to communicate with production
personnel.
The Model 230’s system mode can also
be set to on-air with special sidetone. This
is provided specifically to support on-air
applications where only a “mix-minus”
cue signal is provided to the on-air talent.
