Overview

The RS-702 is a two-channel analog beltpack with an XLR-6 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.

The RS-702 is compatible with all Encore partyline products as well as the PL-Pro line and other partyline systems via Encore interfaces.
