The gray 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: 9. Does the receiver have a stereo output? Will I be able to separate the tracks or are they stuck together as one mono file?

A: Yes, the dual-channel receiver in the Polsen UWM-2 2-Person Camera-Mount Wireless Omni Lavalier Microphone System for Cameras and Smartphones (538 to 586 MHz) implements a stereo 3.5mm output and each transmitter signal can be separated out of the receiver via the provided cable options.

Q: 10. What are the reasons for choosing one of the frequency ranges (470-558 or 558-608) over the other?

A: It also depends where you will be using the device. You can use sites like https://en-us.sennheiser.com/sifa to find which frequency bands in your target area are free or busy. This will narrow it down. If you travel abroad, certain frequencies may be banned or license only. Worth doing a little research into what you need where you are going.
