Yaesu MD-100A8X Dynamic Desk Microphones

7 Customer Reviews

Yaesu MD-100A8X Dynamic Desk Microphones are the latest version of the venerable MD-100 Series and deliver your voice with punch and clarity.

These attractive cardioid desk mics have been a standard Yaesu transceiver accessory for many years, with features that enhance your station operations. Their selectable low-cut filtering and high-emphasis active filtering allow you to tailor the microphone response for optimum voice clarity or DX punch. These MD-100A8X microphones are designed for base station operation with the latest Yaesu HF Transceivers.

The base of the MD-100A8X includes a large push-to-talk (PTT) switch and latching button, along with a large rotary up/down, slow/fast control for scanning. Jacks and cabling are provided to accommodate transceivers having either RJ-45 or round 8-pin MIC jacks.

A multi-axis pivoting mount lets you adjust the horizontal and vertical position of the microphone to accommodate various locations and heights, or you can remove the microphone from the base and use it independently (an auxiliary toggling PTT button is provided, but the audio filtering and scan controls cannot be used).

The OFF position on the Low Cut Switch provides flat-audio-characteristic transmit audio. Position 1 attenuates low audio tones, for improved clarity in moderate band conditions, or if you have a naturally deep voice. Position 2 attenuates low audio tones more than Position 1, for improved clarity in noisy band conditions. To work contest pileups, the HIGH EMPHASIS filter provides even crispier audio.

Note: The Low Cut Switch is ignored when the HIGH EMPHASIS switch is ON, and when the MAIN switch is set to THRU.
