The COS-11D-PT-TA4 is a miniature lavalier microphone with a 1.8 meter cable with a TA4 connector custom wired depending on the transmitter specifications that is being used

Sanken has introduced the COS-11D, a new version of the popular lavalier which overcomes digital transmitter RFI (radio frequency interference). In today's wireless transmission systems the microphone must remain unaffected by new forms of digital transmitter signals. While the benefits of these new systems are obvious, they present new challenges in the area of emission protection. In many cases, noise levels increase and the S/N ratio is deteriorated by the interference of digital transmitters. Sanken has designed the COS-11D specifically the instances where interference is an issue.

The COS-11D joins the COS-11 tradition of providing an ideal solution for live broadcasting, location recording and studio applications. To provide a wide scope of applications, four colors are available in the COS-11D series: Black, Gray, Beige and White.
