Designed after the durable RS-500 Series, the RS-703 is an analog two-channel intercom beltpack that is rugged and light-weight. Able to withstand the inevitable drop or tumble of everyday production environments, the RS-703 carries power and audio through the XLR-3 line connector. Each beltpack combines high headroom, low-noise audio and shaped frequency contour (the “Clear-Com Sound”) to deliver clear audio.
The RS-703 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. Plus, no matter what Clear-Com Partyline system you utilize, the RS-703 beltpack is fully compatible with current and previous Clear-Com analog partyline systems.
A concealed DIP switch panel on the back of the beltpack allows users to easily adjust control features such as switching between headset types, setting volume levels for headphones, adjusting overall volume settings per channel, enabling LED signals,adjusting the functions of the Call and Talk keys per channel, and selecting Clear-Com/RTS functionality.
