YAESU - M-70 - DESKTOP MICROPHONE FOR YAESU RADIO TRANSCEIVERS - DOUBLE CONNECTOR: RJ-45 AND ROUND

The new Yaesu M-70 condensor desktop microphone is the successor of the good-old dynamic MD-100A8X.

The M-70 utilizes a directional condenser microphone element which is specially tuned the frequency response to create clear and crisp audio for radio communication.
Built-in Low-Cut filter allows to shape the low frequency response (cut off at 340Hz, -6dB/octave).
An isolation transformer is integrated in the circuit board to enhance the 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.
ON/ OFF is selectable by a sliding switch located on the bottom of the microphone

The M-70 is compatible with all YAESU HF transceivers equipped with round 8-pin microphone connector or 8-pin modular microphone connector.
The RJ45 and 8P sockets in the base of the M-70 are internally bridged 1:1.
The supplied microphone cable has RJ45 on one side and an 8-pin round plug on the other. You can therefore use the cable for devices with RJ45 as well as for devices with an 8-pin round microphone plug. Simply reverse the cable.
