Minimize RF Interference with Sanken’s Advanced Design Technology
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 to diminish the instances where interference is an issue. Endorsed by wireless transmitter manufacturers, the COS-11D PT incorporates exclusive design advances that deal with both digital and digital/analog hybrid RF wireless transmission.

Focusing on the latest challenges in wireless technologies, Sanken has partnered with industry leaders to provide a breakthrough microphone designed to minimize the instances where RF interference is an issue.
