MODEL 370A
INTERCOM BELTPACK
Sidetone – Level
Choices are Off, Low, Medium Low,
Medium, Medium High, and High.
The Model 370A includes a sidetone
function that allows microphone audio
coming from the microphone preampli-
fier to be sent to the both channels of
the headphone output. This serves as a
user confirmation that they are actively
sending audio to either or both of the talk
output channels. Sidetone audio will only
be routed to the headphone output when
either or both of the talk channels are
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
associated with this channel is going to be
monitored but talk audio is not allowed to
“join” this specific intercom channel.
System – Mic Kill
Choices are Off, Device ID, Global Kill
Command, and Device ID/Global Kill
Command.
The mic kill function allows an enabled talk
channel to be disabled by remote con-
trol. Specifically, it’s possible to remotely
change all active (on) talk channels to
their off state. This function is sometimes
referred to as a “talk off” function. There
are two means available to remotely dis-
able all active talk channels. The Device ID
method uses the identification command
