The COS11D is a commonly used cardioid pattern lavalier microphone. Easy to conceal and can be supplied with mounting accessories on request. The COS-11D, overcomes RFI (radio frequency interference) from a digital transmitter. In today’s wireless transmission systems the microphone must remain unaffected by new forms of digital transmitter signals. 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.Four colors are available in the COS-11D series: Black, Gray, Beige and White.
