Studio Technologies Model 545DR Overview

The Studio Technologies Model 545DR allows for two-channel analog party-line (PL) intercom circuits and devices to be incorporated into Dante audio-over-Ethernet applications. Commonly used in theater, entertainment, and education applications, Model 545DR now allows two-channel analog PL to work with a wide range of products, including RTS TW products.

Just one Ethernet connection can provide power and multichannel audio integration. For added flexibility, a separate external power source of 12 VDC can power the unit. The front panel uses LEDs to provide status of the Ethernet and Dante connections. And for further configuration capabilities of audio parameters, the STcontrolller application can be used to monitor real-time operations.

For RTS TW Series
The Dante networking technology inside the Model 545DR has been designed to transport the two send and two receive audio channels of the RTS TW 2-channel analog intercom circuit. This popular party line intercom technology is directly compatible with the Model 545DR.

Note: For compatibility with Clear-Com single-channel analog party line products, see Model 545DC.

Audio Applications
There are three main ways the Model 545DR can be used—connecting analog party-line intercom circuits into Dante-based systems, adding party-line intercom support for matric systems, and linking two standalone analog part-line intercom circuits. Both input and output channels are fully capable of being connected to Dante-based circuits.
Party-Line Interfacing
Using a unique detection function, the Model 545DR can remain stable if an active belt pack becomes disconnected. With up to 150mA of current available, a typical entertainment application can connect up to three RS-501 or five RS-701 belt packs to each of the two interfaces, eliminating the need for an external intercom power supply and reducing extra system cost and space.
Dante Audio-Over-Ethernet
At the center of Model 545DR is the Dante audio-over-Ethernet networking technology. Audio resolution is set to a sample rate of 48 kHz and a bit depth of up to 24. Channel routing is then configured with the Dante Controller application.
Analog Hybrids With Auto Nulling
The analog hybrids feature provides low noise and distortion, good frequency response, and high return-loss, even if used in non-ideal circumstances. To achieve significant trans-hybrid loss, the hybrid auto null technology accounts for resistive, inductive, and capacitive conditions that are connected to the party-line cabling.
Simple Installation
Both data and power can be provided using an Ethernet connection into the RJ45 connector on the rear of the unit. If redundant power is required in your setup, an external 12 VDC power source can be connected via a 4-pin female XLR connector. Lastly, the party-line intercom connections are made using two 3-pin male XLR connections.
