Lavalier Microphone
COS-11D series
Superb Sound in a New Generation Ultra-
miniature Lavalier Mic
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
transmit
ter 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 to diminish the instances where interference is an
issue.
The new COS-11D joins the COS-
11 tradition of providing an ideal solution for live
broadcasting, location recording and studio applications. To provide a wide sco
pe of
applications, four colors are available in the COS-
11D series: Black, Gray, Beige and
White.
