The headphone output monaural mode
feature was specifically included so that
a special “2-channel headphone mix”
mode can be created. By enabling the
mono mode, the two front-panel user level
controls (“pots”) can be used to create
the desired “mix” of signals being sent
to the headphone output. Many applica-
tions, especially in production settings,
can benefit from this capability. The
desired cue sources must be carefully
assigned to take advantage of the monau-
ral mode. The first cue source should be
assigned, using the DIP-type switches,
to the left channel. Its output level will be
adjusted by the left control. The second
cue source should be assigned to the
right channel. Its output level will be
adjusted by the right control.
There is one limitation related to the head-
phone mono output mode. It’s the fact
that the output will be 2-channel mon-
aural. Whatever signal is present on the
headphone output’s left channel will also
be present on the right channel. A stereo
headphone mix can’t be created. But in
most cases this limitation won’t over-
shadow 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 eight switches associated with switch
assembly SW3 are used to configure the
Model 210’s operating modes. Technically,
these switches “talk” to the micro-control-
ler integrated circuit and associated soft-
ware that give the Model 210 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 switch-
es can be changed even while the Model
210 is powered up and operating. The
unit’s operating characteristics will change
in “real-time” in response to configuration
changes.
Main Output Button Mode
Switches SW3-1 and SW3-2 configure
how the main output button 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 out-
put 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.
