System Operating Mode
The system operating mode configuration
is used to select the overall operating mode
of the Model 205. Specifically, the system
operating mode determines how the main
function will operate vis-à-vis the talkback
functions. In addition, the system operating
mode will also determine if the level of the
headphone output is impacted by pushbut-
ton activity. Understanding how the three
system operating modes impact overall
system operation will ensure correct opera-
tion 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
output connector be muted whenever
on-air talent uses a talkback function to
communicate 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 three pushbut-
ton switches to be used simultaneously.
When selected for the appropriate ap-
plication, 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
evident as speakers (or a connected set
of headphones) will be automatically
reduced in level whenever the main, talk-
back 1, or talkback 2 functions are active.
Headphone Output
The three rotary potentiometers (pots),
located on the Model 205’s front panel,
allow level adjustment of the Dante audio
input 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 the potentiometer on
the right side, pot C, will adjust the sidet-
one level. The sidetone mode configuration
determines exactly how the sidetone func-
tion will operate. The gain range configura-
tion allows the overall output level to be
selected. The minimum level configuration
will determine what occurs when the poten-
tiometers 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
