Frequency Synthesized, Portable Wireless Microphone Transmitter with Microphone Mute Switch

Frequency synthesized, portable wireless microphone transmitter with microphone mute switch. Includes C-216 carrying case, and BC-216 belt clip.

The M-175 personal transmitter is a professional quality, compact body-worn transmitter designed for reliable one-way remote communication. 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 for the most natural sound possible.

A headset microphone option is available (HM-100CL) providing an effective way to control background noise, enhance intelligibility, and ensure high gain before feedback. The transmitter's mic On/Off switch allows users to turn Off the microphone input while allowing the aux input to remain On.

The aux input on the M-175 allows earphone level audio signals for portable media players to be transmitted. When aux input signal is present with the mic On/Off switch turned On, the aux input signal attenuates 6 dB to prioritize the speaker's voice.
