four modes impact overall system opera-
tion will ensure that correct operation and
maximum usability will occur. When select-
ed to one of the three 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 applica-
tions. It’s imperative that the main output
be muted whenever on-air talent is using
one the talkback functions to communi-
cate with production personnel.
Two of the three on-air modes allow talk-
back output 2 to serve non-talkback ap-
plications. When set for the on-air with
talkback out 2 as “hot mic” output mode
the signal coming from the output of the
microphone preamplifier, by way of the
compressor circuit, is routed directly to
talkback output 2. Any signal presented to
the microphone input will be present on
talkback output 2. No muting of talkback
output 2 will ever take place, no matter
what buttons are pressed.
When the system mode is set for on-air
with talkback output 2 follows main output
status the output associated with talkback
2 will always have the same signal as is
present on the main output. This serves as
a copy or “mult” of main output, with the
caveat that the signal on talkback output 2
will always be post-compressor. In this
system mode the button associated with
the talkback 2 function will not impact talk-
back output 2.
When the system mode is set for produc-
tion, the main output is never muted in
response to a talkback output being
active. This mode allows the main output
to be used, for example, as an additional
talkback output. In this way the main and
talkback outputs can be used indepen-
dently, with neither impacting the other.
This also allows all three buttons to be
used simultaneously.
In summary, when selected for the
correct application, each of the four sys-
tem modes can prove to be very useful.
A thorough study of how they impact the
Model 220’s operation can lead to many
interesting and powerful uses.
Conclusion
Once the switches have been set to the
desired configuration, it may be time to
reattach the security plate. The exception
is if the trim pots associated with the line
inputs are going to be adjusted. Details
are provided later in this user guide. The
plate attaches using the four rubber bum-
pers. They should be hand-tightened only;
no tools are to be used.
Operation
At this point the desired input, output,
and power connections should have been
made. The button labels may have been
revised. Finally, the configuration switches
should have been set. Normal operation
of the Model 220 can now begin. The unit
will begin functioning as soon as a power
source is connected. As previously
