Clear-Com RS-702 2-Channel Analog Intercom Belt Pack

Rugged, light-weight and ergonomically designed Clear-Com's RS-702 is a two-channel analog beltpack that can carry power and audio through the XLR-6 line connector. Each beltpack combines high headroom, low-noise audio and shaped frequency contour (the “Clear-Com Sound”) to deliver clear audio.

WIth an improved design, the RS-702 comes in a reliable casing with a retro-design connection to the previous RS-500 Series beltpacks. A belt clip allows a variety of ways to use the beltpack; users can clip it to a belt or lanyard, or users can mount the belt clip to a wall, pole or desk for fixed installations.

Compatible with all Encore partyline products, as well as the PL-Pro line and other partyline systems via Encore interfaces, the RS-702 incorporates LEDs on the top of the beltpack for visual indication of incoming and outgoing call signaling. A mic preamp enables intelligible voice communication for every volume level. Recessed rotary volume control, Talk and Call keys guard against accidental activation. The RS-702 has low operating current to allow for more beltpacks in a daisy-chain. Additionally, a thumbwheel level adjustment is available for Program In.
