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. A metal windscreen, holder clip, rubber mount, and plastic case are included.

Related Questions and Answers

Q: 1. What quality Lav mics can be used with this system? Sennheiser locking ones need an adpater- can someone post a SKU/Product for that adapter? Or some alternatives to the Rode ones which are on back order

A: You can use any 1/8'' microphone that requires mic plugin power like B&H # TRTR50BNLSET or B&H # MIMSLM

Q: 2. I am having trouble using this with Zoom. Without turning up the gain so much that I get feedback, my students cannot hear me because the levels are so low, even though I am maxed out on my PC and my sound mixer level. I cannot use the app because I am running though a physical sound mixer. any suggestions on how to make this louder? Using an adapter 3.5 to TRS for the sound mixer input.

A: Hello, sorry to hear about the issue. what type of adapter are you using? If your input is a balanced input, it's causing cancelation because one side will be out of phase. You most likely need to convert the TRS to TS (mono) going into your mixer.

Q: 3. Does the built-in recording capability of the Rode transmitter make a separate digital audio recorder (such as Zoom) unnecessary, at least for less frequent/demanding work?

A: The built-in recording function is certainly useful, but it is usually preferable to have all recordings made on one device when possible for convenience and the ability to have tracks synced more easily.

Q: 4. Can I buy multiple sets to use for group settings of 4 - 6 people with one receiver unit on the camera?
