audio receiver (input) and audio transmitter
(output) channels must be routed. The con-
figuration settings will be stored in non-
volatile memory within the Model 45DC’s
circuitry. The Model 45DC uses the Ultimo
2-input/2-output integrated circuit to imple-
ment the Dante architecture. This dictates
which parameters can be configured and
what choices are available.
The audio receiver (input) and transmit-
ter (output) channels associated with the
Model 45DC’s Dante interface must be
assigned to desired sources and destina-
tions. This will typically be done with the
Dante Controller software application which
is available for download free of charge at
www.audinate.com. Versions are available
to support Windows® and OS X® oper-
ating systems. Within Dante Controller a
“subscription” is the term used for routing
a transmitter flow (a group of output chan-
nels) to a receiver flow (a group of input
channels). Note that as of the writing of this
guide the Ultimo integrated circuit limits
the number of Dante flows to two in each
direction (two transmitter and two receiver).
These can either be unicast, multicast, or
a combination of the two.
The Model 45DC has a default Dante
device name of ST-M45DC followed by
a unique suffix. The suffix identifies the
specific Model 45DC that is being config-
ured; it relates to the MAC address of the
unit’s Ultimo integrated circuit. The Model
45DC provides two Dante transmitter
(output) channels with the default names
of From PL Ch1 and From PL Ch2. The
Model 45DC has two Dante receiver (input)
channels with default names of To PL Ch1
and To PL Ch2. Using Dante Controller
these names can be revised as appropriate
for the specific application.
The Model 45DC only supports an audio
sample rate of 48 kHz but does have the
ability to select a pull-up/pull-down value.
This value can be selected using the Dante
Controller application. The Model 45DC
can serve as the clock master for a Dante
network but in most cases that would not
be optimal.
Model 45DC units will typically be used in
either of two configurations: “point-to-point”
or in association with other Dante-enabled
equipment. The first configuration finds
two units working together to “link” two
physical locations. At each location there
will either be one or two existing party-line
intercom circuits or one or two sets of user
devices. The two Model 45DC units will be
operating “point-to-point,” interconnected
by way of the associated Ethernet network.
For this application the audio routing would
be very simple. To PL Ch1 on each unit
would be routed to From PL Ch1 on the
other unit. And To PL Ch2 on each unit
would be routed to From PL Ch2 on the
other unit.
The other typical applications will have one
Model 45DC connected to one or two exist-
ing party-line intercom circuits or support-
ing one or two sets of user devices. The
unit’s audio channels would be routed to
input and output audio channels on associ-
ated Dante-enabled equipment. For exam-
ple, the RTS ADAM matrix intercom system
provides Dante interconnection capability
using its OMNEO interface card. The au-
dio channels on the Model 45DC would
be routed to and from audio channels on
the OMNEO card. Other equipment that
supports Dante, such as audio consoles
or audio interfaces (Dante-to-MADI, Dante-
to-SDI, etc.), can have their audio channels
routed to and from a Model 45DC.
