MODEL 371A
INTERCOM BELTPACK
is available for download free of charge
at www.audinate.com. Versions of Dante
Controller are available to support Win-
dows® and OS X® operating systems.
The Model 371A uses the Ultimo 2-input/
2-output integrated circuit to implement
the Dante architecture.
The two Dante transmitter (Tx) channels
associated with the Model 371A’s Dante
interface must be assigned to the desired
receiver (Rx) channels. This achieves rout-
ing the Model 371A’s two talk output audio
channels to the device (or devices) that will
be “listening” to them. Within Dante Con-
troller a “subscription” is the term used for
routing a transmitter flow (a group of output
channels) to a receiver 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 371A’s transmitter
channels need to be routed using more
than two flows it’s possible that an interme-
diary device, such as the Studio Technolo-
gies Model 5422 Dante Intercom Audio
Engine, can be used to “repeat” the signals.
(Use the Model 5422’s pass-thru group con-
figuration mode to provide this resource.)
The two Dante receiver (Rx) channels
associated with the Model 371A’s audio
inputs also need to be routed to the Dante
transmitter (Tx) channels provided by the
desired source device. These two audio
signals can be sent to the Model 371A’s
headphone output.
The Model 371A supports an audio sample
rate of 48 kHz with no pull-up/pull-down val-
ues available. The Model 371A 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 371A has a default Dante
device name of ST-M371A- followed by a
unique suffix. The suffix identifies the spe-
cific Model 371A 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
two Dante transmitter (Tx) channels have
default names of Ch1 and Ch2. 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 371A Configuration
Many of the Model 371A’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 the
STcontroller software application be avail-
able 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) and
is compatible with personal computers
running Windows operating systems that
are version 7 and later. STcontroller ver-
sions 2.02.00 and later are required to
fully support the Model 371A. If necessary,
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 371A unit or units that are to be
configured.
