ANNOUNCER’S CONSOLE
Headphone Gain Range
The overall level of the headphone output
can be configured as desired for specific
applications. The default setting, low, is de-
signed so that users with typical audio input
sources will be inclined to set the rotary
potentiometers at approximately 50% of
rotation. This would be appropriate for most
applications. The high setting would be ap-
plicable in cases where an extreme head-
phone output level is required or the audio
input sources are providing a level that is
lower than typical. Using the high setting in
the former application is not recommended
as hearing damage could result from expo-
sure to high signal levels.
Headphone Minimum Level
A setting in STcontroller is used to configure
the headphone output’s minimum level. In
the –40 dB setting the minimum headphone
output level is approximately 40 dB below
its maximum; the headphone output chan-
nels will never fully mute. This ensures
that any audio signal present on the uti-
lized Dante input channels will always be
present on the headphone output. In most
on-air broadcast applications this is the ap-
propriate setting, ensuring that a minimum
amount of signal is always present. When
full mute is selected moving a level potenti-
ometer to its fully counterclockwise position
will cause its associated headphone output
channel (or channels) to fully mute. If a
potentiometer is set to serve as a balance
control, moving it to either its fully coun-
terclockwise or fully clockwise position will
cause the associated signal to fully mute.
Selecting the full mute mode may be appro-
priate for applications where minimizing the
chance of audio “leakage” is important. This
could occur when during an event the con-
nected headset or headphones are at times
placed on a desk or tabletop.
Note that the action of pot C, when con-
figured to provide the sidetone function
(headphone modes 1, 2 or 3), will never be
impacted by the setting for the headphone
minimum level. Whenever pot C is control-
ling the sidetone level it will always cause
the signal to fully mute when it’s set to fully
counterclockwise.
Sidetone Mode
STcontroller allows the Model 204’s sidet
-
one function to be configured as desired.
Sidetone is audio from the microphone
input that is sent to the headphone output
channels. This can be important, allowing
the user to “hear” themselves for perfor-
mance confirmation and comfort. Making
a specific selection from among the four
available modes will depend on the needs
of the application. If a “full mix” is being
provided to the Model 204’s Dante inputs
then locally-provided sidetone won’t be
needed and the off configuration should be
selected. The user will hear themselves by
way of audio signals being routed to the
Dante input channels. But if “mix-minus” au-
dio is being supplied to the Model 204 then
selecting a headphone source and routing
modes which enables sidetone (headphone
modes 1, 2, or 3) can be an important
means of establishing user confidence.
Then the sidetone mode configuration will
establish exactly when sidetone audio will
be sent to the headphone output channels.
Four sidetone modes are available:
• Off: In this mode the sidetone function is
not active.
• Main Button: In this mode the sidetone
function will be active whenever the
audio signal associated with the micro-
phone input is present on the Dante
main output channel and the microphone
output connector.
