The Yaesu M100 is a microphone that combines a high-quality Condenser and Dynamic element, resulting in a hybrid design. The Condenser Microphone Element provides clear and crisp audio with a greater overall frequency response, while the Dynamic Microphone Element enhances low and mid-range frequency response. The microphone base features one-touch buttons that allow the elements to be used independently or in combinations, ensuring optimal sound quality for each individual's unique voice characteristics.

To shape the low and high-frequency responses, the M100 includes built-in Low-Cut and High-Cut controls. These controls allow users to adjust the transmitted audio characteristics according to their preferences and operating conditions. The Low-Cut control has a cut-off at 340Hz, -6dB/octave, while the High-Cut control has a cut-off at 2kHz, -6dB/octave.

The M100 also comes with a Treble Boost Cowling (TBC) that enhances the voice response attributes in the 1,000 - 1,500 Hz range. This feature helps develop a penetrating signal with a condensed and specific texture. The microphone's PTT key utilizes three Air-Cylinder Tubes, offering a smooth and comfortable keystroke without a hard "click". The magnetic switch ensures long life and stable operation, while the ON AIR LED Indicator clearly indicates when the PTT circuit is active. The microphone cable supplied with the M100 can be used to provide power to compatible Yaesu HF transceivers.

In addition to its features, the M100 comes with a microphone cable, Treble Boost Cowling, Operating Manual, and Warranty Card. The microphone specifications include a Dynamic and Condenser Microphone Element, a supply voltage of DC 5.0 V ± 10%, a frequency range of 30-17000 Hz, a sensitivity of -60 dB (1 kHz, 0 dB = 1 V/1 Pa), an impedance of 600 Ohms, dimensions of 5 x 11 x 5.4 inches (126x280x137mm), and a weight of 2 lbs.

The Yaesu M100 is an exceptional station asset, whether users require wider-range audio with more presence or focused energy to cut through pile-ups. It is a valuable addition for current Yaesu HF radio owners, providing them with an exciting new microphone for their ham radio operations.
