Yaesu MD 100 A8X Desktop Microphone

Base Station Desktop Dynamic Microphone especially designed for the FT-1000MP and FT-900 transceivers, but also compatible with: FT-747, FT-757GX, FT-840, FT-890, FT-990, and FT-1000. The MD-100A8X will work with past HF models that include the ROUND 8-pin jack. (some models may not benefit from the scan function)Selectable low-cut filtering and high-emphasis active filtering that allow you to tailor the microphone response for optimum voice clarity or DX punch. Designed for base station operation with the latest Yaesu HF Transceivers A multi-axis pivoting mount lets you adjust the horizontal and vertical position of the microphone to accomodate 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 filering and scan controls cannot be used). 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 accomodate transceivers having either RJ-45 or round 8-pin MIC jacks. Low Cut Switch The Off position 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 autio dones more than Px 1, for improved clarity in noisy band conditions. To work contest pileups, the HIGH EMPHASIS filter provides even crispier audio. Note: This switch is ignored when the HIGH EMPHASIS switch is ON, and when the MAIN switch is set to THRU.
