Yaesu M-1 Reference Microphone
60th Anniversary Black
For a one-time special Yaesu are offering a 60th Anniversary version of the M-1, embellished with an
elegant gold ring. Please understand that Yaesu are producing only a limited quantity of the special version and take
orders for these units on first-come first-serve basis.
The M-1 Reference Microphone is the ultimate, high-quality, innovative desktop microphone, dedicated to the most
discriminating Ham Radio Operators. It features combined Condenser and Dynamic microphone elements.
The Condenser Microphone Element produces greater frequency response and clear, crisp audio characteristics
perfect for being heard on crowd bands and in big DX pile-ups, while the Dynamic Microphone Element delivers the
rich low-mid tonalities, favored for local QSOs. The response of each microphone element may be adjusted
independently using the internal Nine (9) Band Graphic Equalizer. Each element has a separate volume control for
independent adjustment of output levels. The output of each microphone may be selected separately, or they may be
combined to produce the most pleasant tonality.
Both the Condenser Element and Dynamic Element in the M-1 utilize the Nine (9) Band Graphic Equalizer (63Hz,
125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz, 16kHz). Each element’s frequency response is independently
adjustable. Two (2) frequency response memories and a “through” mode are provided for each element, and are easily
switchable by one-touch buttons on the microphone base.
The supplied TBC (Treble Boost Cowling) enhances the voice response around the important 1 – 1.5kHz range.
Attaching the cowling creates a condensed unique tonal texture that is pleasing for many.
The PTT key uses three Air-Cylinder Tubes which afford a smooth and comfortable long keystone. The contactless
magnetic switch ensures long-life and stable operation.
Other included features are; Recording and playback capability (20 seconds), to confirm the audio tonality; Large red
TX LED Indicator; Large Graphic Equalizer and Frequency Response Scope LCD Display with anti-reflective coating;
Headphone jack; Touch PTT keylock; Built-in low-cut filter to shape the low frequency response; Cannon-type (XLR)
output plug connector; and Audio output volume control for headphones. Two screwdrivers are included to precisely
adjust the graphic equalizer and microphone gains.
