Dante Conﬁguration

To integrate the Model 45DR into an ap-

plication a number of Dante-related param-

eters can be conﬁgured. At a minimum,

the audio input (receiver) and audio output

(transmitter) channels must be routed. The

conﬁguration settings will be stored in non-

volatile memory within the Model 45DR’s

circuitry. The Model 45DR 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 input (receiver) and output

(transmitter) channels associated with the

Model 45DR’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 45DR has a default Dante de-

vice name of

ST-M45DR followed by a

unique sufﬁx. The sufﬁx identiﬁes the spe-

ciﬁc Model 45DR that is being conﬁgured;

it relates to the MAC address of the unit’s

Ultimo integrated circuit. The Model 45DR

provides two Dante output (transmitter)

channels with the default names of

From PL Ch1 and From PL Ch2. The

Model 45DR has two Dante input (receiver)

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 45DR 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 45DR

can serve as the clock master for a Dante

network but in most cases that would not

be optimal.
Model 45DR 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 an existing party-line inter-

com circuit or a set of user devices. The

two Model 45DR 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 45DR connected to an existing

party-line intercom circuit or supporting

a set of user devices. The unit’s audio

channels would be routed to input and out-

put audio channels on associated Dante-

enabled equipment. For example, the RTS

ADAM matrix intercom system provides

Dante interconnection capability using its

OMNEO interface card. The audio chan-

nels on the Model 45DR would be routed

to and from audio channels on the OMNEO

card. Other equipment that supports Dante,

such as audio consoles or audio interfaces
