Clear-com RS-702 2-Channel Wired Beltpack

Clear-com 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.


The RS-702 features LEDs on 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.

DIP Switches and LEDs

A concealed DIP switch panel on the back of the beltpack allows the capability to select audio and key options quickly and easily. DIP switches can control features such as switching between electret or dynamic headsets, setting a minimum or off level for headphone output, adjusting volume settings, enabling or disabling LED signals, having Call on Talk or latching
the Talk key for Channel A, having Call on Talk or latching the Talk key for Channel B, Channel B Minimum Volume setting. A green LED indicates that the beltpack is powered and a green LED on the Talk key indicates that the microphone is active (Talk is latched). An amber LED indicates a Call signal on the channel.

Improved Design

The RS-702 is designed in a rugged and 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.


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