MODEL 374A
INTERCOM BELTPACK
The four Dante receiver (Rx) channels
associated with the Model 374A’s audio in-
puts also need to be routed to the desired
Dante transmitter (Tx) channels. These four
audio signals can be sent to the Model
374A’s 2-channel headphone output.
The Model 374A supports an audio sample
rate of 48 kHz with no pull-up/pull-down
values available. The Model 374A can
serve as the clock master for a Dante net-
work but in most cases it will be configured
to “sync” to another device that is serving
as the “grand master.”
The Model 374A has a default Dante
device name of ST-M374A- followed by a
unique suffix. The suffix identifies the spe-
cific Model 374A that is being configured.
The suffix’s actual alpha and/or numeric
characters relate to the MAC address of
the unit’s Ultimo integrated circuit. The four
Dante transmitter (Tx) channels have de-
fault names of Ch1, Ch2, Ch3, and Ch4.
The four Dante receiver (Rx) channels have
default names of Ch1, Ch2, Ch3, and Ch4.
Using Dante Controller the default device
name and channel names can be revised
as appropriate for the specific application.
Model 374A Configuration
Many of the Model 374A’s operating pa-
rameters can be configured to match
the needs of specific applications. The
STcontroller software application is used
to observe a unit’s current configuration
and perform any changes that are required.
No DIP switch settings or other local ac-
tions are used to configure the unit. This
makes it imperative that STcontroller be
available for convenient 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 comput-
ers running Windows operating systems
that are version 7 and later. STcontroller
versions 2.02.00 and later are required
to fully support the Model 374A. If neces-
sary, download and install STcontroller
onto a designated personal computer. This
personal computer must be on the same
local area network (LAN) and subnet as
the Model 374A unit or units that are to be
configured.
STcontroller allows observation and selec-
tion of functions that include:
• Microphone Input – Electret Power
• Microphone Input – Gain
• Headphone Output Channel Routing
• Sidetone – Level
• Button Operation
• System – Mic Kill
Changes made using STcontroller will be
immediately reflected in the unit’s opera-
tion; no Model 374A “reboot” is required.
Each time a change is made the four talk
buttons on the top panel will momentarily
flash orange in a distinctive pattern to indi-
cate that a command from STcontroller has
been received.
Using STcontroller
Immediately after starting STcontroller
the application will locate and display the
devices that it can control. The one or more
Model 374A units that are recognized will
appear in the device list. Use the Identify
command to allow easy recognition of a
specific Model 374A unit. Double clicking
on a device name will cause the associated
