    KB-702GM - Overview

    The ClearCom KB-702GM is a two-channel intercom system speaker station with a gooseneck mic input and VOX circuitry. Ideal for theater, live performances, industrial applications, and small TV facilities this remote speaker station allows you to select between two channels of party-line communications, with the ability to talk and/or listen on the selected channel. The user can listen via the integral speaker or may use a headset or telephone-style handset - and can talk via a headset mic, a telephone handset, or a push-to talk microphone.

    The KB-702GM features a gooseneck-mic iput and VOX circuitry, for hands-free full-duplex communications without a headset. A switch allows you to choose between the optional GM-9 or GM-18 microphone (sold separately) and the headset connector. The adjustable close-in VOX feature automatically detects the user's voice at the mic and dips the level of the integral speaker while increasing the gain of the microphone, performing in the opposite manner when listening. The potential for acoustic feedback is minimized while permitting natural conversation levels and dynamics.

    Microprocessor-controlled logic and switching yields a feature-rich intercom station in a compact format. Electronic switching for the talk button, blue-color LED (on), amber color LED (o), permits momentary or latching operation. For call signaling, a bright LED lights when a call is activated on a connected intercom channel. A defeatable audible call signal, with level control, is also provided. Separate level controls supply intercom level and a balanced program input. A local program source may be fed to the station, allowing the user to monitor that source while remaining in contact on the intercom system. The balanced program input can also be used in conjunction with the stage-announce output of a main station to provide a paging interrupt, allowing paging at the KB station even if the intercom volume control is turned down. A set of option dip switches is located at the top of the circuit board. Switches are provided for mic-latch disable (momentary-only talk), long-line operation, channel selection, call signal tracking, and audible call signaling. This versatile station can be wall or console mounted in a standard U.S. 4-gang electrical box.


    Please Note! This item is just one component of a larger system. Please refer to the diagram for ideas and recommendations for your Clear-Com intercom system. Diagram shown is a recommendation for a small broadcast station with simple partyline.
