be routed using more than two flows it’s pos-
sible 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 pro-
vide this resource.)
The two Dante receiver (input) channels as-
sociated with the Model 372A’s 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 372A’s 2-channel head-
phone output.
The Model 372A supports an audio sample
rate of 48 kHz with no pull-up/pull-down val-
ues available. The Model 372A 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 372A has a default Dante device
name of ST-M372A- followed by a unique
suffix. The suffix identifies the specific Model
372A 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 one Dante
transmitter (Tx) channel has a default name
of Ch1 . The two Dante receiver (Rx) chan-
nels 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 372A Configuration
Many of the Model 372A’s 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

Dante Configuration
For audio to pass to and from the Model
372A requires that several Dante-related
parameters be configured. These configu-
ration settings will be stored in non-volatile
memory within the Model 372A’s circuitry.
Configuration will typically be done with the
Dante Controller software application which
is available for download free of charge at
www.audinate.com. Versions of Dante Con-
troller are available to support Windows® and
OS X® operating systems. The Model 372A
uses the Ultimo 2-input/2-output integrated
circuit to implement the Dante architecture.
One transmitter (output) channel and both
receiver (input) channels are utilized.
The Dante transmitter (output) channel as-
sociated with the Model 372A’s Dante inter-
face must be assigned to the desired Dante
receiver (input) channel. This achieves rout-
ing the Model 372A’s one talk output audio
channel to the device (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 chan-
nels) 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 372A’s transmitter channel needs to
