The Model 545DR Intercom Interface is the suggested replacement for the factory-discontinued Model 45DR Intercom Interface.
The Model 545DR is designed for applications that utilize 2-channel party-line (PL) intercom circuits. Dante audio-over-Ethernet media networking technology is used to transport the two send and two receive audio channels. Two Model 545DR units can interconnect by way of an Ethernet network. Alternately, a Model 545DR can interconnect with other devices such as matrix intercom systems, DSP processors, and audio consoles. Party-line power and termination can be supplied by the Model 545DR, allowing direct connection of user beltpacks such as the RTS® BP325. Housed in a lightweight tabletop enclosure with optional mounting kits. Power-over-Ethernet (PoE) powered.
