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 the 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 3-pin LEMO connector and is wired for use with Lectrosonics transmitters. A metal windscreen, holder clip, rubber mount, and plastic case are included.

Q: 10. No, Im sorry let me re-ask my question - I already have a UWP system and want to up grade to a Sony UTX-B40 Wireless Bodypack Transmitter. For one, the UTX series has a dual receiver meaning they can take in 2 frequencies, etc, UWPs need individual receivers for each transmitter, but the UTS series too, use TRS mic inputs, just like the UWP series, which can take the Sanken Cos-11 lavs. What would happen if I connected the TRS connector from the Cos-11D into a Sony UTX-B40 Wireless Bodypack Transmitter? Is the Cos11D exclusively for UWP series TRS connectors? (and Sennheisers?

A: This particular mic will work with the UTX-B40 transmitter. It will not work with Sennheiser.
