The gray Sanken COS-11D Lav Mic for Lectrosonics, Grayis 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 tiny 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 non-servo-bias Lectrosonics transmitters. A metal windscreen, holder clip, rubber mount, and plastic case are included.

Q: 3. Do I need to purchase anything else beside the antena?

A: This should work with any receiver but this antenna needs DC power. Many receivers can supply DC at the antenna port, but if yours does not you'd need to consider how you are going to supply power to it. You can use a DC power supply if you are close enough to an AC outlet. If not, you'd need to supply power via a DC inserter between the receiver antenna jack and the cable to the antenna. Lectrosonics makes this. Part number is BIAST and also needs a CH12 power supply.
