The M-175 personal transmitter is a professional quality, compact body-worn transmitter designed for reliable one-way remote communication. It's ideal for many applications including: personal cueing, assistive listening, tour guide presentations, communication for on-the-job training (requiring being some distance away or in a noisy environment), and other personal, one-way remote communication situations.

For a natural sound, this transmitter incorporates the latest digital and analog technologies to produce high quality sound with low residual noise, wide dynamic range, and extended frequency response.

The audio processing circuit allows a choice of companded 2:1 audio processing when used with COMTEK full fidelity receivers, or non-companded 1:1 audio processing on prescribed channels with COMTEK and other lower cost popular receivers. Both audio processing systems have the same frequency response of 80 Hz to 10 kHz. Operating under FCC Regulation Part 90, the M-175 transmitter has greater transmission range and reliability.

M-175 Special Features

The aux input on the M-175 transmitter allows earphone level audio signals from digital media players to be transmitted. When turned on, the microphone mute switch attenuates the aux input signal 6 dB to prioritize the speaker's voice. The CB-36 ST aux input cable is supplied with the transmitter.

A variety of headset micropohones are available from COMTEK providing an effective way to control background noise, enhance intelligibility, and ensure high gain before feedback. This makes it great for many speciality applications.
