Product Overview
The Model 545DC Intercom Interface integrates two analog party-line (PL) intercom circuits and their user devices into Dante® audio-over-Ethernet applications. This cost-effective, reliable, and user-friendly solution is commonly used in theater, entertainment, and education. The Model 545DC directly supports both analog party-line (PL) and Dante and is fully compatible with Clear-Com®'s single-channel analog party-line (PL) products. Two hybrid circuits with automatic nulling action deliver exceptional audio quality and separation of send and receive audio. A simple Ethernet connection suffices for connecting the Model 545DC to Dante-compatible devices.
