The black Sanken COS-11D Omni Lavalier Microphone with Normal Sensitivity and TA4F Connector for Trantec 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 TA4F connector and is wired for use with Trantec transmitters. Accessories are available separately and are not included with this configuration of the microphone.

Q: 8. Wil it work with a Sennheiser ME 4 Cardioid Lavalier Microphone with Locking 3.5mm Connector ? Will it provide voltage ?

A: The input on the Rode Wireless GO II transmitter is standard 3.5mm TRS non-locking connector. The transmitter will supply the appropriate voltage (plug-in power) that the mic requires to function. However, the Sennheiser ME 4 uses a 3.5mm TRS locking connector which may not attach properly to the transmitter since its input is not threaded like those on Sennheiser wireless transmitters and the mic's locking ring has no thread to lock onto.

Q: 9. Does the transmitter work if hidden and placed behind the subject's back?

A: It will work depending upon the line of sight distance from the receiver.

Q: 10. Can I plug a Dynamic Mic into the transmitter with an XLR-female to 3.5mm adapter? Would the levels work, or would it overload the unit? ie, SM58, adapter cable, Wireless GO II

A: The audio input signal would be too hot. Attenuation would be required.
