The Yaesu MD-200A8X ultra-fidelity desktop mic was unveiled at the 2001 Dayton Hamvention. This stylish, high-quality desk microphone is designed for the latest generation of Yaesu HF transceivers. The MD-200A8X employs a studio-quality Polyethylene Teraphthalate Film Dynamic element, optimized for high fidelity SSB operation, allowing faithful reproduction of the operator's voice during operation with negligible distortion.
Yaesu's exclusive VSPC (Variable Side Pressure Control) allows the operator to adjust the frequency response of the microphone, from a totally flat response to a high-articulation response with moderate peaking about 2000 Hz. The VSPC technique provides this response control without the distortion and reduced signal-to-noise ratio that can accompany active "equalizer" circuits.
The MD-200A8X also includes provision for the incorporation of a user-supplied Dynamic, Magnetic or Crystal microphone element, allowing A-B selection of the supplied dynamic element and the custom element. A slide switch on the base of the mic allows easy switching. This mic also has up-down scanning and transmit LED that are supported by most Yaesu radios.
The MD-200A8X is constructed using a heavy-duty aluminum die-cast base and support frame, with a rubber shock absorber for the mic element housing to dampen low frequency vibrations. The mic cable terminates to an Yaesu 8 pin mic plug.
Yaesu lists these as compatible models:
FT-817, FT-840, FT-847, FT-857, FT-897, FT-900, FT-920, FT-990, FT-1000, FT-1000D, FT-1000MP, FT-1000MP Mark V. (However, these models do not support the TX LED function during transmit: FT-840, FT-990, FT-1000 and FT-1000D).
