Introduction
The Model 45DC Dante™ to Dual Party-Line
Intercom Interface is designed for applica-
tions that utilize single-channel analog par-
ty-line (PL) intercom technology. The unit
provides two independent single-channel
interfaces that each support one party-line
audio channel. Single-channel party-line
intercom systems are commonly used in
theater, entertainment, and education appli-
cations where a simple, reliable, low-cost,
and easy to use solution is desired. Analog
party-line products from Clear-Com® and
ASL are directly compatible with the Model
45DC. The Dante Audio-over-Ethernet me-
dia networking technology is used to trans-
port the send and receive audio channels
associated with each of the two party-line
circuits. 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 45DC is directly
compatible with the latest broadcast and
audio equipment that uses Dante technol-
ogy. An Ethernet connection is all that’s
required to make the Model 45DC part of a
sophisticated, networked audio system.
A Model 45DC can interconnect with de-
vices such as matrix intercom systems,
DSP processors, and audio consoles. The
Model 45DC is directly compatible with the
RTS ADAM® OMNEO® matrix intercom
network. Alternately, two Model 45DC units
can interconnect by way of the associated
Ethernet network. The Model 45DC can be
powered by Power-over-Ethernet (PoE) or
an external source of 12 volts DC. Two par-
ty-line power sources with impedance ter-
mination networks can be supplied by the
Model 45DC, allowing connection of two
sets of user beltpacks such as the Clear-
Com RS-501 and RS-701. A Model 45DC
