MODEL 372A
INTERCOM BELTPACK
settings or other local actions are used to
configure the unit. This makes it imperative
that the STcontroller software application
be available for use in a personal computer
that’s connected to the related LAN.
STcontroller is available free of charge
on the Studio Technologies’ website (www.
studio-tech.com/stcontroller-application/)
and is compatible with personal computers
running Windows operating systems that
are version 7 and later. STcontroller version
2.01.00 or later is required to support the
Model 372A. If necessary, download and in-
stall STcontroller onto a designated personal
computer. This personal computer must be
on the same local area network (LAN) and
subnet as the Model 372A unit or units that
are to be configured.
Parameters
STcontroller allows observation and selec-
tion of functions that include:
• Microphone input electret power on/off
• Microphone input gain
• Headphone input-to-output channel routing
• Sidetone level
• Talk button operation
Changes made using STcontroller will be
immediately reflected in the unit’s opera-
tion; no Model 372A “reboot” is required.
Each time a change is made the talk button,
located on the top panel, will momentarily
flash orange to indicate that a command
from STcontroller has been received.
Using STcontroller
Immediately after starting STcontroller the
application will locate and display the de-
vices that it can control. All Model 372A units
that are present on the network will be rec-
ognized and display on the device list. Use
the Identify command to allow easy recogni-
tion of a specific Model 372A unit. Double
clicking on a device name will cause the
associated configuration menu to appear.
Review the current configuration and make
changes as required.
Microphone Input – Electret Power
Choices are Enabled or Disabled .
If the headset has an electret microphone
that requires a source of low-voltage DC
power for operation enable the Electret Pow-
er check box. In virtually all cases a gaming
or computer headset that uses a 3.5 mm
TRRS plug will require microphone power.
If the associated headset has a dynamic
(non-powered) microphone do not enable
the Electret Power check box. Most broad-
cast headsets that terminate on 5-pin male
XLR connectors will not require microphone
power. The on/off status is displayed by way
of a red LED, labeled MIC POWER, that is
located adjacent to the Headset A connector.
Note that the Model 372A cannot supply P12
or P48 phantom power that may be required
for balanced condenser (capacitor) micro-
phones. This should not pose an issue as
this type of microphone is essentially never
associated with a headset that would be
used for intercom applications.
Microphone Input – Gain
Choices are
24 dB
,
30 dB
,
36 dB
,
42 dB
,
and 48 dB .
Dynamic microphones have an output level
that is typically lower than that provided by
electret microphones. As such, the 36, 42,
or 48 dB gain settings will probably be
appropriate for them. Electret microphones
often have internal circuitry which provides
a relatively high output level. The 24 and
30 dB gain settings will typically be appropri-
ate for use with this type of microphone.
