MODEL 374A
INTERCOM BELTPACK
The four Dante receiver (Rx) channels
associated with the Model 374A’s audio
inputs also need to be routed to the de-
sired 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 Leader clock for a Dante
network but in most cases it will be config-
ured to “sync” to another device.
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
default names of Ch1, Ch2, Ch3, and
Ch4. The four Dante receiver (Rx) chan-
nels 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 spe-
cific application.
Model 374A Configuration
Many of the Model 374A’s operating
parameters can be configured to match
the needs of specific applications. The
STcontroller software application is used
to observe a unit’s current configura-
tion and perform any changes that are
required. No DIP switch settings or other
local actions are used to configure
the unit. This makes it imperative that
STcontroller be available for convenient
use in a personal computer that’s con-
nected to the related LAN.
Installing STcontroller
STcontroller is available free of charge
on the Studio Technologies’ website. If nec-
essary, 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.
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
configuration menu to appear. Review the
current configuration and make changes
as required.
Parameters
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
• System – Call Indication
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.
