The beige Sanken COS-11D Omni Lavalier Microphone with Normal Sensitivity and LEMO 3-Pin Connector for Wisycom 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 Wisycom transmitters. A metal windscreen, holder clip, rubber mount, and plastic case are included.

Related Questions and Answers

Q: 1. Is this safe to use with the Verizon 5G frequency ban? The FCC says 600MHz, but it also says something about some ranges in the 500MHz frequency band as well.

A: The Sennhieser EW 112P G4 UHF wireless systems work within the FCC- allowed range of 470-608MHz. 5G cellular service operated on higher frequencies than this. Sennheiser wireless systems allow for auto scanning, with 1680 frequencies to choose from, making it easy to find a clean frequency, even in the crowded UHF spectrum. .

Q: 2. The manual says to set AF Out on the receiver to +18 dB. Is this true? Why not 0db?

A: In general, Camera preamps are not the best quality. +18db ensures that you will need the least amount of preamp gain possible, which will maximize the quality you capture with the camera.

Q: 3. Will the o rings fit with the Rode NTG2 on Sony's PXW-X70?

A: Thank you for you inquiry. The O-Ring is normally used with the CS1E which is 19mm and the Rode NTG2 is 22mm. I would say that should not be too much of a stretch and will work fine. Please let us know if you have any other questions or concerns.Best,Peter Hanniganplus24/Sanken323-845-1171

Q: 4. How does this system compare to the Sony UWP-D21?

A: You will get very similar quality and range out of either system and both are very highly preferred for professional applications. Either of these are great for using many wireless microphone systems in the same space and at the same time, without running into interference with each other. If you are only going to require a set up with one or two wireless microphones running at the same time, then I recommend considering something more like the Sennheiser AVX system because it will give you the same great quality and it is more compact as well, even though it is not quite as frequency agile as the above solutions.

Q: 5. Will this work with the MixPre-10 II?

A: Yes, the Sennheiser EW 512P G4 Camera-Mount Wireless Omni Lavalier Microphone System (GW1: 558 to 608 MHz) will work well alongside the Sound Devices MixPre-10 II 10-Channel / 12-Track Multitrack 32-Bit Field Recorder.

Q: 6. Does the G4 system work with the Sanken COS-11D?

A: Yes it does. The Sanken mic is far better than the one that comes with the kit and it is perfectly compatible.

Q: 7. Will these fit a RDE NTG-3?

A: The Sanken O-Rings will fit a Rode NTG-3 and mics with a similar diameter 19-22mm.

Q: 8. Would I need this for a Rode NTG-3 to put on a Canon XA-35?

A: Spacers such as the Sanken O-Rings will be required for the NTG-3 and most similar shotgun mics when mounting to a cameras built in mount such as the Canon XA35. These mounts are designed oversized to accommodate a wide variety of mics and mic types.

Q: 9. How exactly do you use these? Do you put one on the mic or multiple? I find no instructions on using them.

A: They go one on the top of the other till the microphone fits properly inside the camera mount/shock mount you trying to use the microphone with.

Q: 10. If I purchase a Sennheiser SKP 500 G4 Pro separately in the future, can it used with this EW 512 G4 model?

A: Yes, the Sennheiser SKP 500 G4 Pro plug-on transmitter is compatible for use with the EK 500 G4 Pro receiver that is included with the EW 512P G4 wireless lavalier system as long as both components operate on the same frequency band. You will need to purchase an SKP 500 G4 transmitter on the same frequency band as the EW 512P G4 system. The EK 500 G4 receiver can be used with only one transmitter at a time so you will have the option of using it with either the SK 500 G4 bodypack transmitter that is included in the EW 512P G4 system or using the SKP 500 G4 plug-on transmitter.
