Audio-Technica ATM75cW Headworn Microphone

The ATM75cW is the cardioid condenser headworn microphone from Audio-Technica's ATM75 family, cabled for UniPak body-pack transmitters. The fixed-charge condenser element reproduces speech and vocals with natural detail, and the cardioid pattern focuses on the wearer while rejecting monitors and ambient noise to resist feedback. A pivot-mounted flexible boom descends from either the left or right side, so the mic sits where the presenter wants it and holds a steady mic-to-mouth distance on the move.

A 55 inch cable terminates in a locking 4-pin connector for Audio-Technica UniPak body-packs. It ships with the AT8139L large windscreen, the AT8139S small windscreen, and the AT8439 cable clip.
