We are pleased to introduce the new YAESU Dual-Element Microphone - Model M-100. The new M-100
Microphone features a hybrid design - integrating high-quality Condenser and Dynamic elements.
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) 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.
While the recently released M-1 microphone provides the ultimate flexibility in enhancing each user's
distinctive voice characteristics - utilizing a full-featured Nine Band Graphic Equalizer - we are confident
that the carefully selected feature configuration of the new M-100 offers the advantage of combining the
two different microphone element characteristics with simplified operation, all at a very attractive price point.
