MODEL 371A
INTERCOM BELTPACK
The compressor active LED, labeled
COMP and visible adjacent to the headset
connector, can act as a guide when set-
ting the microphone preamplifier gain.
During normal talk operation the com-
pressor active LED should light intermit-
tently. If, for example, with a dynamic
microphone the LED rarely lights and the
preamp gain is set to 42 dB it might be a
good idea to change it to 48 dB. If the LED
is lit fully during normal talking in a situ-
ation where the headset has an electret
microphone and the gain is set for 30 dB,
changing it to 22 dB might be warranted.
Sidetone – Level
Choices are Off, Low, Medium Low,
Medium, Medium High, and High.
The Model 371A includes a sidetone func-
tion that allows microphone audio coming
from the microphone preamplifier to be
sent to the headphone output. This serves
as a user confirmation that they are ac-
tively sending audio to one or more of the
talk output channels. Sidetone audio will
only be routed to the headphone output
when either or both of the talk channels
is active. The level of the sidetone audio
can be selected from among five values.
The correct value is simply the one that
makes the user most comfortable. Side-
tone audio can also be disabled by se-
lecting Off. Selecting Off would be useful
only in special applications such as during
troubleshooting or where user talk audio is
being returned as part of their listen audio
signals. The two rotary level controls will
not impact the sidetone level.
Button Operation
Choices are Push to Talk, Latching,
Push to Talk/Tap to Latch, and Disabled.
This configuration section allows indepen-
dent selection of how the two talk buttons
will function. When the Push to Talk mode
is selected the operation is self-explanato-
ry. Only when a talk button is pressed and
held will talk audio be sent out its associ-
ated Dante transmitter channel.
When the Latching mode is selected tap-
ping (momentarily pressing) the button
will cause the function to “latch” into the
talk active mode. Tapping the button again
will cause the function to “unlatch” and
talk will no longer be active.
When the Push to Talk/Tap to Latch mode
is selected a “hybrid” function of sorts is
enabled. Pressing and holding the talk
button will enable audio to be sent out
its associated Dante transmitter channel.
When the button is released audio will
stop being sent out its associated trans-
mitter channel. Tapping (momentarily
pressing) the button will cause the func-
tion to “latch” into the talk active mode.
Tapping the button again will cause the
function to “unlatch” and talk will no lon-
ger be active.
Many applications are best served when
the buttons are configured in the Push to
Talk mode. This ensures that a channel
can’t accidentally be left in its talk active
mode. But there are certainly valid situa-
tions when the Latching or Push to Talk/
Tap to Latch modes setting will prove to
be very useful.
When the Disabled mode is selected
microphone audio will never be sent out
the associated Dante transmitter channel.
This can be useful when the audio input
