Introduction
The Model 45DR Dante™ to 2-Channel
Party-Line Intercom Interface is designed
for applications that utilize 2-channel ana-
log party-line (PL) intercom technology.
This type of intercom is commonly used
in broadcast, corporate, and commercial
applications where a simple, reliable, easy
to use solution is desired. The RTS® TW-
series of 2-channel intercom equipment is
directly compatible with the Model 45DR.
The Dante Audio-over-Ethernet media
networking technology is used to trans-
port the two send and two receive audio
channels associated with the party-line
circuit. Two hybrid circuits with automatic
nulling provide excellent audio quality and
high return-loss. (These hybrid circuits are
sometimes referred to as 2-wire to 4-wire
converters.) The Model 45DR is compat-
ible with the latest broadcast and audio
equipment that uses Dante technology. An
Ethernet connection is all that’s required
to make the Model 45DR part of a sophis-
ticated, networked audio system.
A Model 45DR can interconnect with
devices such as matrix intercom systems,
DSP processors, and audio consoles. The
Model 45DR is directly compatible with the
RTS ADAM® OMNEO® matrix intercom
network. Alternately, two Model 45DR units
can interconnect by way of the associated
Ethernet network. The Model 45DR can
be powered by Power-over-Ethernet (PoE)
or an external source of 12 volts DC. A
party-line power source and impedance
termination networks can be supplied by
the Model 45DR, allowing connection of
user beltpacks such as the popular RTS
BP-325. A Model 45DR can also connect
with an existing powered and terminated
intercom circuit. Audio level meters pro-
