The Studio Technologies Model 545DC Intercom Interface allows two single-channel analog party-line (PL) intercom circuits and associated user devices to be incorporated into Dante® audio-over-Ethernet applications. Single-channel analog party-line (PL) intercom systems are commonly used in theater, entertainment, and education applications where a simple, reliable, low-cost, and easy-to-use solution is desired.
Dante has become a major method of interconnecting audio signals and various devices using standard Ethernet networks. The Model 545DC directly supports both analog party-line (PL) and Dante, providing excellent performance in both domains. Single-channel analog partyline (PL) products from Clear-Com® are directly compatible with the Model 545DC. The Dante audio-over-Ethernet media networking technology is used to transport the send and receive audio channels associated with the two single-channel party-line (PL) circuits. The Model 545DC's two hybrid circuits with automatic nulling action provide good separation of send and receive audio with high return loss and excellent audio quality. (These hybrid circuits are sometimes referred to as 2-wire to 4-wire converters.) The Model 545DC's digital audio signals are compatible with all equipment that utilizes Dante technology.
An Ethernet connection is all that's required to make the Model 545DC part of a sophisticated, networked audio system.
