The gray Sanken COS-11D Omni Lavalier Microphone with Normal Sensitivity and 2.5mm Connector for Lectrosonics 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 2.5mm connector and is wired for use with Lectrosonics wireless transmitters. A metal windscreen, holder clip, rubber mount, and plastic case are included.

Q: 9. Would this lavalier mic work in europe? italy?

A: The wireless systems that are sold by B&H are intended for use in North America without a license. The FCC regulations vary in different countries, so a license may be required. The A1: 470 to 516 MHz, A: 516 to 558 MHz, and G: 566 to 608 MHz frequency bands for the Sennheiser EW 112P G4 Camera-Mount Wireless Omni Lavalier Microphone System are all able to be used in Italy, however, a license is required. As additional options for a Sennheiser wireless system that you can use in Italy without a license, you may want to consider the Sennheiser AVX-ME2 SET Digital Camera-Mount Wireless Omni Lavalier Microphone System (B&H #SEAVXME2SET4) or the Sennheiser XSW-D LAVALIER SET Digital Wireless Omni Lavalier Microphone System (B&H # SEWXSLSTR). The AVX system operates on the 1.9 GHz frequency band and includes a plug-in receiver which can be connected to a 3.5mm mic input using the included XLR to 3.5mm cable. The XSW-D system operates on the 2.4 GHz frequency band and can also be used with an XLR female to 3.5mm cable to connect to a 3.5mm mic input. Both systems include the Sennheiser ME 2 II Lavalier Microphone, which is the same microphone that is included with the EW 112P G4 system.

Q: 10. What frequency would you recommend for Washington DC?
