2-Channel Beltpack with XLR-3 Connector
RS-703
The RS-703 is a two-channel analog beltpack that can carry power and audio through the XLR-3 line connector. Each beltpack combines high headroom, low-noise audio and shaped frequency contour (the “Clear-Com Sound”) to deliver clear audio.
Note: Access the Encore Power Supply Calculator to estimate power requirements for analog partyline systems.
