NBA论坛 The RS-701 is a single-channel analog beltpack from Clear-Com that can carry power and audio through the XLR-3 line connector. Fully compatible with current and previous Clear-Com analog partyline systems, the RS-701 beltpack combines high headroom, low-noise audio and shaped frequency contour (the “Clear-Com Sound”) to deliver clear audio.

The RS-701 features 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-701 has a low operating current to allow for more beltpacks in a daisy-chain.
