The white Sanken COS-11D Omni Lavalier Mic with Sennheiser Connectoris a subminiature lav mic 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 little 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 Sennheiser transmitters. A metal windscreen, holder clip, rubber mount, and plastic case are included.

Q: 5. Can you add additional wireless transmitter mics to the camera mounted receiver ? If so what models are compatible ?

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.

Q: 9. 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: 10. Does this work with a Panasonic G85 or G95 camera?

A: Yes, the Sennheiser EW 112P G4 Camera-Mount Wireless Omni Lavalier Microphone System would work with the Panasonic Lumix G85 Mirrorless Camera, as the camera has the necessary 3.5mm microphone input connection. The EW 112P G4 includes an adapter to mount the receiver onto the camera shoe, as well as the appropriate cable to connect the receiver's output to the camera's input. It does not appear that the Panasonic Lumix G95 Mirrorless Camera has the necessary 3.5mm microphone input connection, however.
