Studio Technologies Model 545DC Intercom Interface

Studio Technologies Model 545DC Intercom Interface

The 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 party-line (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.

The Model 545DC can interconnect with Dante-supported devices such as matrix intercom systems, digital audio processors, and audio consoles. The unit is directly compatible with RTS ADAM^® and ODIN^® intercom systems that support OMNEO^® network technology. Alternately, two Model 545DC units can be interconnected by way of an associated Ethernet network. The Model 545DC can also become part of a party-line (PL) intercom system when used in conjunction with devices such as the Model 5421 and Model 5422A Dante Intercom Audio Engine units from Studio Technologies. In this way, analog party-line (PL) intercom circuits can become part of a high-performance digital party-line (PL) intercom deployment.

The Model 545DC can be powered by Power-over-Ethernet (PoE) or an external source of 12 volts DC. The unit can provide two party-line (PL) power sources and analog impedance termination networks, allowing direct connection of user beltpacks such as the Clear-Com RS-501 and RS-701 devices. A Model 545DC can also connect to one or two existing powered and terminated single-channel analog party-line (PL) intercom circuits. The unit provides four audio level meters that help to confirm system performance during setup and operation. Support for transporting industry-standard call light signals between two Model 545DC units, as well as between a Model 545DC and other compatible units, is also provided.

The STcontroller software application can be used to real-time monitor and control several Model 545DC operating parameters. In addition, two configuration settings are performed using the application. Versions of STcontroller are available that are compatible with the Windows^® and macOS^® operating systems. They are available, free of charge, from the Studio Technologies' website.

Standard connectors are used for Model 545DC party-line (PL) intercom, Ethernet, and DC power interconnections. Set up and configuration of the Model 545DC is simple. A Neutrik^® etherCON RJ45 jack is used to interconnect with a standard twisted-pair Ethernet port associated with a local-area network (LAN). This connection can provide both PoE power and bidirectional digital audio. LEDs provide status indications of the Ethernet and Dante connections.

The unit's lightweight aluminum enclosure is intended for desk or tabletop use. Optional mounting kits allow one or two Model 545DC units to be mounted in one space (1U) of a standard 19-inch rack enclosure.
