The Model 45DR Dante to 2-Channel Party-Line Intercom Interface is designed for applications that utilize 2-channel analog 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 transport 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 compatible 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 sophisticated, 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 Vdc. 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 provide confirmation of system performance during setup and operation. Support for transporting call light signals between Model 45DR units is also provided.
