The Clear-Com KB-702GM Remote Speaker Station is a dual-channel, half-duplex intercom station designed for flexible, hands-free communication across professional environments. Building on the proven KB-702 platform, the KB-702GM adds a gooseneck microphone connector and VOX (voice-activated) circuitry for improved convenience and audio performance.
Users can select between two partyline channels, listening via the built-in speaker or headset, and speaking through a headset mic, telephone handset, push-to-talk mic, or the optional gooseneck microphone. Internally programmable DIP switch modes allow for custom operation, while balanced program input with level control and visual/audible call signaling ensure clarity and reliability in every setup.
The KB-702GM can be wall-, console-, or V-Box-mounted for portable or desktop use, and includes an optional 4-wire daughter board for enhanced system integration. Ideal for broadcast, theater, and live event communications, it delivers flexibility, clarity, and professional-grade durability.
