MODEL 373A
INTERCOM BELTPACK
(or devices) that will be “listening” to it. Within
Dante Controller a “subscription” is the term
used for routing a transmitter (Tx) flow (a
group of output channels) to a receiver (Rx)
flow (a group of input channels). The number
of transmitter flows associated with an Ultimo
integrated circuit is limited to two. These can
either be unicast, multicast, or a combination
of the two. If the Model 373As transmitter
channel needs to be routed using more than
two flows it’s possible that an intermediary
device, such as the Studio Technologies’
Model 5422 Dante Intercom Audio Engine,
can be used to “repeat” the signals. (Use the
Model 5422’s pass-thru group configuration
mode to provide this resource.)
The two Dante receiver (input) channels as-
sociated with the Model 373As audio inputs
also need to be routed to the Dante transmit-
ter (output) channels provided by the desired
source device. These two audio signals can
be sent to the Model 373As 2-channel head-
phone output.
The Model 373A supports an audio sample
rate of 48 kHz with no pull-up/pull-down val-
ues available. The Model 373A can serve as
the clock master for a Dante network, but in
most cases it will be configured to “sync” to
another device that is serving as the “grand
master” for the Dante implementation.
The Model 373A has a default Dante device
name of ST-M373A- followed by a unique
suffix. The suffix identifies the specific Model
373A that is being configured. The suffix’s
actual alpha and/or numeric characters relate
to the MAC address of the unit’s Ultimo inte-
grated circuit. The one Dante transmitter (Tx)
channel has a default name of Ch1. The two
Dante receiver (Rx) channels have default
names of Ch1 and Ch2. Using the Dante
Controller application the default device
name and channel names can be revised
as appropriate for the specific application.
Model 373A Configuration
Many of the Model 373As operating param-
eters 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 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 373A. 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 373A 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 373A “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.
