About Comtek M-175

After extensive research and development, the Comtek M-175 Frequency Synthesized Wireless Microphone Transmitter emerges as a top-tier choice for professionals seeking reliable one-way remote communication. Operating within the 72-76MHz frequency range, this compact, body-worn transmitter is engineered with the latest digital and analog technologies.

The M-175 is designed to deliver superior sound quality, characterized by low residual noise, a wide dynamic range, and an extended frequency response. This results in the most natural and clear audio output possible, making it an ideal choice for professionals in the audio and video industry.

For those seeking additional control over background noise and enhanced intelligibility, the M-175 offers compatibility with the HM-100CL headset microphone. This feature ensures high gain before feedback, providing an effective solution for environments with high ambient noise levels.

One of the standout features of the Comtek M-175 is its microphone On/Off switch. This allows users to conveniently mute the microphone input while keeping the auxiliary input active. This feature is particularly useful when using portable media players, as the M-175's auxiliary input can transmit earphone-level audio signals.

Moreover, the M-175 is designed with a smart attenuation feature. When an auxiliary input signal is present and the microphone On/Off switch is activated, the auxiliary input signal is automatically reduced by 6 dB. This ensures the speaker's voice is always prioritized, making the Comtek M-175 a versatile and user-friendly wireless microphone transmitter.
