The white Sanken COS-11D Omni Lavalier Microphone with Normal Sensitivity and TA4F Connector for Shure Transmitters is a subminiature lav mic 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 TA4F connector and is wired for use with Shure transmitters. A metal windscreen, holder clip, rubber mount, and plastic case are included.

Q: 2. Do Sanken COS-11D for Sennheiser Evo work with other Wireless Transmitters like SONY, Lectrosonics etc.?

A: The 3.5mm connector for Sennheiser will not work with SONY or Lectrosonics- the connector wiring is different for these, so the connector would need to be re-wired to work.

Q: 9. Will this work with Sennheiser AVX?

A: It should work just fine assuming you are using a 1/8 locking connector for the bodypack.

Q: 10. I've plugged this in to my recorder via the Senal PS-48B-35H Phantom Power Supply that's listed as a recommended accessory for this mic, with 48V phantom power turned on. However, I'm getting a very very low signal from the microphone, peaking at around -32Db even with the gain on my recorder turned all the way up. Did I get a dud or is there something I've missed here?

A: So you checked the gain, have you checked the fader? Is their a pad setting switched on the recorder or the Senal? My last suggestion is to check the voltage of LR44 batteries. Maybe they're about dead. Try switching to providing phantom power from the recorder.
