YAESU - M-90D - DESKTOP MICROPHONE FOR YAESU RADIO TRANSCEIVERS - DOUBLE CONNECTOR: RJ-45 AND ROUND
Description
The M-90D utilizes a dynamic microphone element which is finely tuned to provide a rich low to mid frequency response desirable for clear and intelligible conversation.
Utilizing a wind shield and directional microphone element, the M-90D's microphone structure is designed to focus voice input from the front while reducing side-to-side ambient noise.
The integrated low-cut filter creates clear and crisp audio characteristics by shaping the low-frequency response (340Hz cut, -6dB / octave). An isolation transformer is integrated into the printed circuit board to improve audio quality.
The M-90D's PTT uses three Air-Cylinder tubes similar to the M-1 reference microphone. This provides solid and smooth prolonged operation. A simple one-touch PTT key lock button is located directly above the PTT key.
