Product Description
The Studio Technologies Model 45DC Dante to Dual Party-Line Intercom Interface is designed for applications that utilize single-channel analog party-line (PL) intercom technology. The unit provides two independent single-channel interfaces that each support one party-line audio channel. Single-channel party-line intercom systems are commonly used in theater, entertainment, and education applications where a simple, reliable, low-cost, and easy to use solution is desired. Analog party-line products from Clear-Com are directly compatible with the Model 45DC. The Dante audio-over-Ethernet media networking technology is used to transport the send and receive audio channels associated with each of the two party-line circuits. 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 45DC is directly compatible with the latest broadcast and audio equipment that uses Dante technology. An Ethernet connection is all that's required to make the Model 45DC part of a sophisticated, networked audio system.
A Model 45DC can interconnect with devices such as matrix intercom systems, DSP processors, and audio consoles. The Model 45DC is directly compatible with the RTS ADAM OMNEO matrix intercom network. Alternately, two Model 45DC units can interconnect by way of the associated Ethernet network. The Model 45DC can be powered by Power-over-Ethernet (PoE) or an external source of 12 Vdc. Two party-line power sources with impedance termination networks can be supplied by the Model 45DC, allowing connection of two sets of user beltpacks such as the Clear-Com RS-501 and RS-701. A Model 45DC can also connect with one or two existing powered and terminated intercom circuits. Audio level meters provide confirmation of system performance during setup and operation. Support for transporting call light signals between Model 45DC units is also provided.
Standard connectors are used for party-line intercom, Ethernet, and DC power interconnections. The Model 45DC's enclosure has a "1/2-rack" 1U form factor and weighs less than two pounds, making it well suited for use in portable applications. Alternately, using one of the optional rack-mount front panels, one or two Model 45DC units can be mounted in a single space (1U) of a standard 19-inch rack enclosure.
