ANNOUNCER’S CONSOLE
be routed to both the left and right chan-
nels of the headphone output. Its level will
be adjusted using pot B. A stereo pair can
enter the Model 205 by way of Dante input
channels 3 and 4. These signals will be
sent, in stereo, to the left and right channels
of the headphone output. Their level will be
adjusted using pot C.
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 ap-
propriate for applications where minimizing
the chance of audio “leakage” is important.
This could occur when during an event the
connected 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 205’s side-
tone 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 205’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”
audio is being supplied to the Model 205
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 confi-
dence. Then the sidetone mode configura-
tion will establish exactly when sidetone
audio will be sent to the headphone output
channels.
