The Condenser Microphone Element produces greater overall frequency response - with clear and crisp audio characteristics - while the Dynamic Microphone Element delivers enhanced low and mid-range frequency response. A set of one-touch buttons on the microphone base enable the two microphone elements to be used independently or in combinations to create the most favorable sound quality for each person’s unique voice characteristics.

Built-in Low-Cut (cut-off at 340Hz, -6dB/octave) and High-Cut (cut-off at 2kHz, -6dB/octave) controls shape the low/ high frequency responses enabling changes to be made in the transmitted audio characteristics, according to user’s preference and operating conditions.

The supplied TBC - Treble Boost Cowling (shown above left) further enhances the voice response attributes in the important 1,000 – 1,500 Hz range, in order to develop a penetrating signal with a condensed and specific texture. The PTT key actuates three Air-Cylinder Tubes, which afford a smooth and comfortable keystroke – free of a hard “click”. The incorporation of a magnetic switch ensures long-life and stable operation. The highly visible ON AIR LED Indicator clearly informs the user when the PTT circuit is active. The supplied microphone cable can be used to provide power to the M-100 simply by connecting with compatible Yaesu HF transceivers*. Current Yaesu HF radio owners can immediately start using this new microphone as an exciting and valuable addition to their current ham radio operation. Whether it’s for wider-range audio with more presence or focused energy to cut through the pile-ups, the M-100 is an exceptional station asset.
