    CTG Audio FS-800 8 Microphone PSTN Control Console

    Manufacturer: CTG Audio

    Item #: CTGA-FS800   •   MFG #: CTGA-FS800







    Using multiple microphones, this mixer calculates the direction and source of every sound in a room. It can determine if a sound is speech or noise. By measuring the difference in time and intensity of the speech in each microphone, the mixer effectively forms a beam aimed at the person speaking and adaptively follows that person as they move about the room. Constantly monitoring each microphone in real time, acoustic information is added from microphones that do not appear in other microphones.

    An additional De-Reverberation sensor eliminates room reverberations such as voices reflecting off of walls. The result is a degree of voice clarity and intelligibility unprecedented in the past.

    CTG offers two versions of the Beam Forming Mixer. The FS-400 has four microphone inputs with independent Echo and Noise Cancellation on each microphone, plus an additional De-Reverberation Echo Canceller.

    The FS-800 offers eight Microphone inputs with both Echo and Noise Cancellation for each microphone, plus an additional De-Reverberation Echo Canceller for every four microphones.

    Each Mixer can be daisy chained to additional mixers to support an unlimited number of microphones. Every unit can be either master or slave. Microphones may be installed in the ceiling, walls or on tables.

    An included telephone line (PSTN) add and an included wired remote dialer or soft dialer will turn either mixer into a self contained audio teleconferencing system, and line level output and input connections will allow connection to a video codec for video teleconferencing.

    Used with CTG CM-01 Ceiling Microphone, or the TM-01 and TM-02 table top or table implant microphones, high quality conferencing can be available even in many rooms previously considered acoustically unsuitable.
