KB-111A Remote Speaker Station

    Manufacturer Description

    The KB-111A is a high-quality remote speaker station that allows talking and/or listening on one of any two channels in a Clear-Com system (not both simultaneously).

    Compatible with all Clear-Com intercoms, this station features excellent speech intelligibility in high- and low-noise environments. The wide frequency response speaker delivers crisp sound quality at levels high enough to be heard in the noisiest surroundings. 

    The KB-111A operates with a carbon headset, dynamic headset, or a telephone-style handset. It drives a standard Clear-Com headset to levels greater than 110 dB SPL. The station’s speaker can be turned off when private conversation via the headset is desired; alternately, a mic on/off switch is provided to to let the station function as a “listen only” or “remote page” station.

    The station contains a recessed sidetone control, which allows the operator to vary the level of his/her own voice as heard in the headset/speaker. Sidetone control also suppresses acoustic feedback when the mic and speaker at that station are on simultaneously.

    The KB-111A features Visual Call Signaling; the Call button allows you to attract the attention of operators who have removed their headsets or turned off their speakers. The Call lamp illuminates when another operator presses the Call button.

    The station is designed to be custom-mounted. It can be installed on a wall or console, or inside a standard 6" x 8" NEMA electrical box. Clear-Com provides optional portable boxes (see accessories).

    Standard mic cable connects the KB-111A to the intercom system. The station provides a clearly labelled screw-terminal block for interconnection behind the front panel.

    High-impedance current sourcing and low current drain allow as many as 20 KB-111A stations to be connected along one mile of wire with no significant loss of signal level or audio quality. 

    The circuit design virtually eliminates all hum and noise pick-up from SCR dimmer and AC power sources.
