ClearCom KB-702 2-Channel Select Flush Mount Speaker Station
The KB-702 remote speaker station permits the user 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 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 adjustable sensitivity,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 (off), 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 are provided for intercom level and for 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 canal so 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.
These versatile stations may be wall or console mounted in a standard U.S. 4-gangelectrical box, or may be mounted in the optional V-Box for desktop, surface-mount,or portable applications.
Either of the stations may be used with the optional 4-wire or TW (two channels on a single mic cable) daughter boards. On the TW board, the stations become plug incompatible with a Clear Com TW system.The 4-wire board creates separate send and receive circuits, so that the station may be attached to fiber-optic lines or other audio routing systems with 4-wire connections.The stations are powered by the intercom line or by a local power supply when used with the optional 4-wire daughter board.
THE CLEAR-COM CONCEPT
Clear-Com is a closed-circuit intercom system that consistently provides high-clarity communication in high-noise and low-noise environments. A basic system consists of a single- or multi-channel power supply or main station connected to various single- or multi-channel remote stations, such as beltpacks and loudspeaker stations. Clear-Com manufactures a wide variety of both portable and fixed-installation units. All are compatible with each other. Clear-Com intercom systems can also interface with other communication systems and devices.
