Yaesu M-90D Desktop Microphones utilize a finely tuned dynamic element to deliver rich low to mid frequency response, desirable for a clear and concise conversational sound that is pleasing to the ear of the listener. The oversize dynamic microphone element and windscreen of the M-90D is designed to accentuate voice input from the front and limit ambient noise and sounds from the side. The attractive desk stand base of the M-90D features a large PTT bar switch, a PTT lock button, and both 8-pin modular and round connectors at the back. By swapping the orientation of the supplied coiled cord cable with 8-pin round and modular connectors at either end, the M-90D may be used with virtually any Yaesu HF transceiver*. For difficult band conditions, a built-in, low-cut filter creates clear and crisp audio characteristics by shaping the low frequency response (cut off at 340Hz, -6dB/octave). An integrated isolation transformer enhances the audio quality of this fine microphone, which also uses three air cylinder tubes, similar to the M-1 Reference Microphone, to provide a lifetime of solid, smooth, and noiseless PTT operation.
