The beige Sanken COS-11D Lavalier Mic for Lectrosonics Transmittersis a subminiature lav microphone designed to deliver clear, full-bodied sound and reliable performance, making it a popular choice among industry professionals in broadcast, TV, theater, film, videography, and more. 

Engineered to meet the standards of modern digital wireless microphone systems, the COS-11D is RF shielded to eliminate interference issues and ensure a pristine audio signal. The microphone capsule features a rectangular design that sits vertically, increasing the surface area and allowing this little mic to offer a rich, full sound that outperforms many larger models.

The mic's 50 Hz to 20 kHz frequency response rolls-off extreme low end and provides accurate, transparent audio reproduction with a small presence boost in the 6 kHz area for crisp, intelligible speech. With a forgiving omnidirectional polar pattern that picks up sound in a 360° pattern, levels stay consistent, even when the subject turns away from the mic.

A water-resistant mesh screen protects against humidity, perspiration, makeup, bad weather, and other potential on-location issues, while the durable cable is also moisture-resistant and built to stay soft and pliable, even after extended use. This version of the COS-11D terminates in a TA5F connector and is wired for use with servo-bias Lectrosonics transmitters. A metal windscreen, holder clip, rubber mount, and plastic case are included.
