ClearCom KB-702 2-Channel Select Flush Mount Speaker Station
The KB-702 remote speaker station permits the user to selectbetween two channels of party-line communications, with the abilityto talk and/or listen on the selected channel. The user can listen viathe integral speaker, or may use a headset or telephone-style handset- and can talk via a headset mic, a telephone handset, or a push-totalkmicrophone.

The KB-702GM adds a gooseneck-mic connector and VOX circuitry,for hands-free full-duplex communications without a headset.A switch allows the user to choose between the optional GM-9 orGM-18 microphone and the headset connector. The adjustablesensitivity,close-in VOX feature automatically detects the user's voiceat the mic and dips the level of the integral speaker while increasingthe gain of the microphone, performing in the opposite manner whenlistening. The potential for acoustic feedback is minimized whilepermitting natural conversation levels and dynamics.

Microprocessor-controlled logic and switching yields a feature-richintercom station in a compact format. Electronic switching for thetalk button, blue-color LED (on), amber color LED (off), permitsmomentary or latching operation. For call signaling, a bright LEDlights when a call is activated on a connected intercom channel.A defeatable audible call signal, with level control, is also provided.Separate level controls are provided for intercom level and forbalanced program input. A local program source may be fed to thestation, allowing the user to monitor that source while remaining incontact on the intercom system. The balanced program input canalso be used in conjunction with the stage-announce output of a mainstation to provide a paging interrupt, allowing paging at the KB stationeven 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 audiblecall signaling.

These versatile stations may be wall orconsole mounted in a standard U.S. 4-gangelectrical box, or may be mounted in theoptional V-Box for desktop, surface-mount,or portable applications.

Either of the stations may be used with theoptional 4-wire or TW (two channels on asingle mic cable) daughter boards. On theTW board, the stations become plug incompatible with a Clear Com TW system.The 4-wire board creates separate send andreceive circuits, so that the station may beattached to fiber-optic lines or other audiorouting systems with 4-wire connections.The stations are powered by the intercomline or by a local power supply when usedwith the optional 4-wire daughter board.
