The M-70 utilizes a directional condenser microphone element which has a prescisely tuned the frequency response to obtain
clear and crisp audio quality.
The PTT uses three Air-Cylinder tubes similar to the Reference Microphone M-1 to provide a solid and smooth extended operation. A
simple one-touch PTT keylock button is placed just above the PTT key for those long rag chews.
Built-in Low-Cut filter allows to shaping of the low frequency response (cut off at 340Hz, -6dB/octave). ON/ OFF is selectable by a
sliding switch located on the bottom of the microphone.
An isolation transformer is integrated in the circuit board to enhance the audio quality.
The M-70 is compatible with all YAESU HF transceivers equipped with round 8-pin microphone connector or 8-pin modular
microphone connector.
