2 Ch. TW Dual Listen Monaural Beltpack

The RS-703 is a two-channel analog beltpack with an XLR-3 line connector and XLR-4M headset connector. A mic preamp with a dynamic range of 130 db enables intelligible voice communication for every volume level, from a whisper to a shout. The beltpack also combines high headroom, low noise audio and shaped frequency contour (Clear-Com Sound) to deliver crystal-clear audio. A thumbwheel level adjustment is available for Program In, as well as a 3.5mm TRS jack for Program Input.

The RS-703 is compatible with all Encore partyline products, as well as the PL-Pro line and other TW partyline systems via Encore interfaces.

*A TWC-701 interface is REQUIRED to connect beltpacks to main station. Only one interface is necessary for each system. Sold separately.
