The beige Sanken COS-11D Omni Lavalier Microphone LEMO 3-Pin Lectrosonicsfor 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. Accessories are sold separately and are not included with this configuration of the microphone.

Q: 1. It's fit My Sony UWP-D11 Transmitter(UTX-B03) ?Thanks,Kelvin

A: Hi Kevin, I work with plus24 who is Sanken's North America Distributor. This part number will fit your Sony UWP-D11 transmitter (UTX-BO3). We do not use a Sony branded connector, but our plug fits and the locking ring fits as well.

A: The Sanken COS-11D Omni Lavalier Microphone with Normal Sensitivity & 3.5mm Locking Connector for Sony Transmitters (With Accessories, Black) is made specifically for Sony wireless transmitters and is not able to be connected directly to camera inputs such as that of the Sony A7III Camera.

Q: 3. 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

Q: 4. would this also work on the Sony URX-P40 mic receiver?

A: The URX-P40 is a receiver, so no, you would not connect a mic to it. It is compatible with the UWP series transmitters, which is compatible with URX-P40 receivers.

Q: 5. 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.
