The M-90D utilizes a dynamic microphone element that is finely tuned to deliver rich low to mid
frequency response desirable for a clear and concise conversation.

Using a windscreen cover and a directional microphone element, the structure of the microphone of the M-90D is designed to concentrate voice input from the front while reducing ambient noise from the side.

Built-in Low-Cut filter creates clear and crisp audio characteristics by shaping the low frequency response (cut off at340Hz, -6dB/octave).

An isolation transformer is integrated in the circuit board in order to enhance the audio quality.

The M-90D and M-90MS* are compatible with all YAESU HF transceivers equipped with the round 8-pin microphone connector or the 8-pin modular microphone connector.

M-90D Desktop Microphone
The PTT of the M-90D uses three Air-Cylinder tubes similar to the Reference Microphone M-1.
This provides solid and smooth extended operation. A simple one touch PTT keylock button is placed directly above the PTT key for those long rag chews
*M-90D does not require the SCU-53 to connect to the transceiver equipped with the round 8-pin microphone
connector.
