• When selected to the on-air mode, the
audio signal on the main output chan-
nel will mute whenever the audio signal
on the talkback output channel is active.
The on-air mode should be selected for
all on-air broadcast applications when
it’s imperative that the audio signal
on the main output channel be muted
whenever on-air talent uses the talkback
output channel to communicate with
production personnel.
• When the system mode is set for pro-
duction with dim, the audio signal on
the main output channel is never muted
in response to the audio signal on the
talkback output channel being active.
In addition, the level of the headphone
output is dimmed (reduced in level or
attenuated) by 18 dB whenever the main
or talkback output channels have audio
present. In this way the two output chan-
nels can be used independently, with
neither impacting the other. And, the
headphone output can be connected
to amplified loudspeakers. The speak-
ers will reduce in level whenever one of
the output channels is active, preventing
acoustical feedback.

Hot Mic Out
Switch 10 selects whether an audio sig-
nal will be present on the hot mic output
channel. This configuration is included so
that an audio signal will not be present un-
less the hot mic function has been specifi-
cally enabled. While the hot mic output
function can be very useful, there may be
applications where the user does not want
their microphone audio signal leaving the
Model 214 unless they select it to do so
using the pushbutton switches.
Note that a Dante transmitter channel for
the hot mic output will always be present
on the Model 214’s digital interface. But
only when DIP switch 10 has been placed
in its enabled position will audio from the
output of the microphone preamplifier be
present on the hot mic output channel.

Operating Modes
Switches 11 and 12 are used to configure
the overall operating mode of the Model
214. Specifically, they determine how the
main output channel operates vis-à-vis the
talkback output channel as well as one
facet of the headphone output’s function.
Understanding how these three modes
impact overall system operation will en-
sure that correct operation and maximum
usability will occur.
