The white Sanken COS-11D Omni Lavalier Microphone with Reduced 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. A metal windscreen, holder clip, rubber mount, and plastic case are included.

Related Questions and Answers

Q: 1. Are there any advantages or disadvantages of using the UC90 version? Is it true that a license is required to use this band.

A: No license is required to use any version of the Sony UWP-D27 within the USA. There is no objective benefit to any frequency block over another, as the frequencies used has no direct effect on audio quality. The only case in which you would prefer one frequency block over another would be if 1. there is radio activity/interference within one band in your area, or 2. if you need to ensure compatibility between this and another Sony wireless device.

Q: 2. What frequency would you recommend for Washington DC?

A: Radio activity varies by day, but for crowded metropolitan areas the UC90 band of the Sony UWP-D27 2-Person Camera-Mount Wireless Omni Lavalier Microphone System is usually safest.

Q: 3. If I already own a UC14 receiver with two transmitters, should I get another set for UC14 or should I get a different frequency band?

A: I would base the decision of whether to get another Sony UWP-D27 2-Person Camera-Mount Wireless Omni Lavalier Microphone System on the same frequency range on how well your current system works. If you find frequencies are always readily available, and the range works well in your area, it may be sensible to get another system on the same range. The UWP-D27 has 2,772 potential frequencies, so adding two for a total of four would not necessarily be detrimental. On the other hand, another frequency range adds versatility if the existing system sometimes struggles to find open channels.

Q: 4. Is there a cable/adapter to use a sanken cos-11BP mic with this system?

A: The Sanken COS-11D-BP Lavalier Microphone has a standard XLR male connector and requires 48V phantom power to function, so it is not compatible for connection to a wireless transmitter with a simple cable adapter. In order to connect the COS-11D-BP to a Sony UTX-B40 Wireless Bodypack Transmitter for the UWP-D27 2-Person Camera-Mount Wireless Lavalier Microphone System, you will need to connect the mic a phantom power supply first to provide sufficient voltage to the microphone, and then you can use an XLR female to locking 3.5mm TRS Sony cable to connect the output from the phantom power supply to the input on the transmitter. As an option, you can use the Xvive Audio P1 Portable Phantom Power Supply with Rechargeable Battery (B&H # XVP1) together with the Sony EC-1.5BX 3.5mm Locking Mini-Plug to Female XLR Cable - 4.9' (B&H # SOEC1.5BX). The Xvive P1 is lightweight and has a built-in rechargeable battery, as well as a belt clip.

Q: 5. Can I use the Sony UWP-D27 to wirelessly feed a Sony A7s from my mixer’s two channel output?

A: Yes, the UWP-D27 2-Person Camera-Mount Wireless System can be used to send a line signal from the left and right outputs of your mixer to your Sony a7s Mirrorless Camera. The 2 x UTX-B40 Wireless Bodypack Transmitters can send the independent left and right outputs of your mixer to the URX-P41D Dual-Channel Camera-Mount Wireless Receiver. The left and right outputs of the URX-P41D Receiver can then send a stereo line signal to your Sony a7s Mirrorless Camera by utilizing the XLR-K3M Dual-Channel Digital XLR Audio Adapter Kit (sold separately).

Q: 6. I own this and want to add a handheld mic to that works with the receiver. Which handheld wireless works best with it?

A: You can use the Sony UTX-M40 Wireless Handheld Cardioid Microphone Transmitter that works in the same frequency band as the URX-P41D receiver (BH #SOUTXM4014). This is made by Sony, for direct compatibility with the URX-P41D receiver. Please keep in mind that you can only use up to 2 wireless transmitters with the URX-P41D receiver at a time.

Q: 7. Can you buy this system without the lav mics?

A: The Sony UWP-D27 is not available without lavalier mics.

Q: 8. Hi. Is the Hi. Is the Sony SMAD-P5 Digital MI Shoe Adapter included?

A: No, the Sony UWP-D27 2-Person Camera-Mount Wireless Omni Lavalier Microphone System does not include the Sony SMAD-P5 Digital MI Shoe Adapter for UWP-D Series (B&H # SOSMADP5). The SMAD-P5 is available separately.

Q: 9. Can I record to one XLR in, sending both transmitters to L and R channels?

A: 3-pin XLR is mono only, so it would not be possible to maintain separation of both right and left channels of the URX-P41D's output when sent into a single XLR input.

Q: 10. What frequency recommendation for Hawaii and is there a website that can best help us find out what frequency is free while traveling for work?

A: All three of Sony's UWP-D frequency bands are compatible for use in Hawaii. The UC14 frequency band (470 to 542 MHz) is the best option and the UC25 band (536 to 608 MHz) is nearly as good. The UC90 band (941 to 960 MHz) will also work. Each band has 2,772 auto-scan frequencies so chances are very good that you will be able to find a clear frequency to use anywhere in the US, Canada, or Mexico.
