The MicroD is primarily a drum and percussion instrument microphone for professional stage and studio applications. The MicroD has a uniformly controlled hypercardioid polar pattern and a smooth, accurate response in its frequency range. This microphone is lightweight, compact, and simple to use. The MicroD is housed in an aluminum ring and isolated by means of a rubber shock mount system. The MicroD hypercardioid microphone attaches easily and firmly to a standard drum rim utilizing the patented DVICE rim mount system. Designed, machined, assembled, and tested by Audix in the USA.
