Sanken COS-11D PT-RM: Pigtail Lavalier, Reduced Sensitivity

Share

The COS-11D addresses the noise issues associated with digital transmitter RFI (radio frequency interference). The wide frequency response ensures accurate, transparent audio reproduction and its omnidirectional polar pattern provides a generous pickup area while minimizing feedback and off-axis noise.

The COS-11D PT-RM version is unterminated (no connector), has a 9dB attenuated sensitivity. Designed with reduced sensitivity, this RM or "Red Mark" version works ideally in high transient (excessive signal peaking) environments without associated noise and peak distortion. An improved water-resistant mesh screen protects against humidity, perspiration, makeup, bad weather, etc. The miniature profile of the lavalier makes it an ideal solution for professional theater, video recording, film and broadcast applications. Accessories included: HC-11 holder clip, WS-11 metal windscreen, RM-11 rubber mount, AA battery, and case. Available in Beige, Black, Gray, and White.
