Main Output Button Mode
Switches SW3-1 and SW3-2 configure
how the main output button functions.
control, located on the far right, will be
used to adjust its level.
There is one limitation related to the head-
phone output mode. It’s the fact that the
output will be 2-channel monaural. What-
ever signal is present on the headphone
output’s left channel will also be present
on the right channel. (The exception is if
the right-channel output is disabled.) A
stereo headphone mix can’t be created.
But in most cases this limitation won’t
overshadow the benefit of being able to
create the mix. For signal-flow clarification
please review the block diagram located
at the end of this user guide.
Operating Modes
The sixteen switches associated with
switch assemblies SW3 and SW4 are
used to configure the Model 233’s operat-
ing modes. Technically, these switches
“talk” to the microcontroller integrated
circuit and associated software that give
the Model 233 its “smarts.” The software
has been carefully designed to provide
a number of different ways in which the
unit can function. It’s critical to carefully
review the available options and choose
the ones that best meet the needs of a
specific application. Note that switches
can be changed even while the Model 233
is powered up and operating. The unit’s
operating characteristics will change in
“real-time” in response to configuration
changes.
In addition to the switch assemblies SW3
and SW4, the last two positions of switch
assembly SW2 are used for configuration.
Specifically, SW2-11 and SW2-12 are used
for the talkback to intercom functions.
Figure 8. Main output button mode settings
There are four available modes:
• Push to mute: In this mode the main
output is normally active. The main
output will mute whenever the button
is pressed and held. This is the “cough”
mode typically used for on-air sports
broadcasting applications.
• Push to talk: In this mode the main out-
put is normally muted. The main output
will become active whenever the button
is pressed and held.
• Alternate action: In this mode the main
output will change between its active
and muted state whenever the button
is pressed. Upon power up the main
output will be in its muted state.
• Hybrid: This mode is a combination
of push to talk and alternate action. It’s
similar to the way talk buttons function
on user stations associated with broad-
cast and production intercom systems.
If the button is pressed and held, the
main output will become active until the
button is released. If the button is mo-
mentarily “tapped” the main output will
change state. Upon power up the main
output will be in its muted state.
