mode will also determine if the level of the
headphone output is impacted by push-
button activity. Understanding how the three
system operating modes impact overall sys-
tem operation will ensure correct operation
and maximum usability.
• On-Air: When the system operating mode
has been selected to on-air the main but-
ton will be forced to be inactive whenever
a talkback function is active. The on-air
mode will be appropriate for all on-air
broadcast applications where it’s impera-
tive that the audio signal on the Dante
main output channel and microphone out-
put connector be muted whenever on-air
talent uses a talkback function to commu-
nicate with production personnel.
• Production: When set for the production
operating mode the status of the main
button will never be impacted by the
status of a talkback function. This mode
allows the Dante main output channel to
be used, for example, as an additional
talkback output. In this way the Dante
main and talkback output channels can
be used independently, with activation
of any of them not impacting any of the
others. This also allows all four push-
button switches to be used simultane-
ously. When selected for the appropri-
ate application, the production operating
mode can prove to be very useful. But it’s
not appropriate for on-air use!
• Production with Dim: This operating
mode functions exactly as the production
operating mode does with one addition.
The level of the headphone output is
dimmed (reduced in level or attenuated)
by 18 dB whenever one of the main or
talkback functions are active. In this way
the headphone output can be connected
to amplified loudspeakers without the risk
of acoustical feedback. The selection of
this operating mode will be clearly evi-
dent as speakers (or a connected set
of headphones) will be automatically
reduced in level whenever the main,
talkback 1, or talkback 2 functions are
active.
Headphone Output
The three rotary potentiometers (pots),
located on the Model 206’s front panel, al-
low level adjustment of the Dante audio in-
put channels and, if enabled, the sidetone
(local microphone) audio signal as they
are sent to the 2-channel headphone out-
put. How the potentiometers function will
depend on the selected audio sources and
routing configuration. Refer to the Configu-
ration section of this guide for details. Five
modes are available and determine the
overall performance. If headphone mode
1, 2, or 3 is selected pot C, located on the
right side, will adjust the sidetone level.
The sidetone mode configuration deter-
mines exactly how the sidetone function
will operate. The gain range configuration
allows the overall output level to be select-
ed. The minimum level configuration will
determine what occurs when the potenti-
ometers are in their fully counterclockwise
position and, in one circumstance, its fully
clockwise position. When pot C is config-
ured for sidetone operation it will always
cause the sidetone audio to mute if it is set
to its fully counterclockwise position
Users should find the headphone audio
quality to be excellent, with high maximum
output level and low distortion. Analog
audio signals do not pass directly through
the potentiometers. The position of each
potentiometer is recognized by the Model
206’s processor which then adjusts the
appropriate signal level within the digital
