The white Sanken COS-11D Omni Lavalier Microphone with Normal Sensitivity and LEMO 3-Pin Connector for Zaxcom 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 3-pin LEMO connector and is wired for use with Zaxcom transmitters. Accessories are available separately and are not included with this configuration of the microphone.

Q: 1. If I'll buy 2 receivers and 2 transmitters, what else I would need to connect it to my DSLR camera? I need to connect 2 people at the same time and I'm intending to use it together with 2 of sanken cos-11d ( i have a NIKON D800 and a Nikon D850)

A: Hi Vasile - to use two receivers on your DSLR, you'll need to split the signals so that they are routed independently to the Left & Right channels of the stereo input on your camera. This can be done using a Stereo Y-cable (e.g. Hosa Technology Stereo 3.5mm Male TRS to Two 3.5mm Female TS Y-Cable (6")). Once captured, you'll need to split the signals in post from a stereo feed into to mono channels (Channel 1 = Left, Channel 2 = Right). Alternately, it may be worthwhile to look into a portable audio recorder as the preamp will be quite an improvement over the mic input on the camera - you can send your signal from the EW Receivers into a camera mounted recorder and use a stereo output to the camera while having much more control over your audio and monitoring with much better quality.

Q: 2. Purchasing two sets of this, would it be smart to buy one of each frequency range? Will both be good in NYC?

A: You can definitely use two of the Sennheiser EW 512P G4 Camera-Mount Wireless Omni Lavalier Microphone Systems that operate on the same frequency band in New York City. The system has 3,520 auto-scan frequencies for the system to select from to transmit audio and up to 32 systems can be used simultaneously on the same band.

Q: 3. How to attach the mirror less camera or gimbal? Photos only show a belt clip on back side.
