The beige Sanken COS-11D Omni Lavalier Microphone with Reduced Sensitivity & LEMO 3-Pin Connector for Lectrosonics Transmitters is 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 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: 4. Hello. Do I need anything additional to use these lavs. I have a SD 633 mixer, and was considering getting these and just running standard xlr cables to these. I did however come across a discussion that talked about using DPA DAD3056 for these lavs?

Q: 10. I have bought this mic and when plugged into my Sennheiser EW-G3 transmitter I get no signal at all, is there a setting I need to change? The transmitter works with ME-2 Mic, recording to a Zoom H6. Thank

A: Hi. This mic is great but comes with some strange and quite dealbreaking features. I sent my first one back due to a high pulsating noise that it created along with very low input volume. Got a new one and same thing. I'm paring it with a Sennheiser G3 unit and a zoom H6 as well and just by chance I notised that I had perfect sound when pulling the plug out of the G3 transmitter a millimiter or so. If you stick it all the way in, it wont work. Obviously this is crap and I'm only using it when I have a subject that I know will be pretty much completely still and I always have to fibble around with it for a while but then again, It produces greeeeat sound for a Lav. /Marcus
