The black Sanken COS-11D Omni Lavalier Microphone with Normal Sensitivity and Locking 3.5mm Connector for Sony 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 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 locking 3.5mm connector and is wired for use with Sony transmitters. Accessories are available separately and are not included with this configuration of the microphone.

Q: 8. i need a sanken mic cos11d for senn ew 100 g3 series just wondering the exact microphone?

A: Sanken COS-11D Omni Lavalier Mic, Normal Sens, Hardwired 1/8 TRS Connector for Sennheiser Evolution Wireless Transmitter (with Accessories, Black), is the correct microphone for the Sennheiser ew100 G3.

Q: 9. 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.

Q: 10. Hi, just wondering if someone could tell me if this is compatible with the SONY UTX-B2 wireless transmitter? Thanks, Ross.

A: As long as it is wired for the transmitter's connection, it should work without a problem.
