Cedar Audio DNS 4 4-Channel Dialogue Noise Suppressor

Share

The CEDAR DNS 4 is the most advanced portable model in the DNS series. With its Hirose HR-10 power input and mini-XLRs for many connections, it takes up little more space than the industry-standard DNS 2 yet doubles the number of channels available.

It's incredibly fast and simple to use—the DNS algorithm requires nothing more than switching on the Learn function that identifies and adapts to the background noise, and then adjusting the amount of noise attenuation required. Notwithstanding this simplicity, it can achieve remarkable results. What's more, despite being so convenient that you can slip it into your pocket or equipment bag, it offers analog line and ultra low-noise microphone inputs (the latter with optional 48V phantom powering), AES3/AES11 digital inputs, and both analog and digital outputs. And, to further increase its flexibility, it runs on 12V power so you can use it in the middle of a field as easily as in the studio or edit suite.

Retaining the near-zero latency of its predecessors, the DNS 4 is suitable for use in all situations—location recording, live-to-air broadcasting and live sound in venues such as theaters and concert halls, conference venues and places of worship, as well as in the studio.

CEDAR's dialogue noise suppression (DNS) technology is used on the highest quality productions and broadcasts to eliminate traffic noise, air conditioning, wind, rain, babble and general background noise from audio. It will help to compensate for unfavorable acoustic conditions and poor microphone placement, and will even suppress excessive reverberation.

It's used to clean up sound for film production, to suppress ambient noise for live broadcasting, to refresh sound libraries, and to enhance speech for audio forensic investigations. It's an industry standard that has earned a string of awards including an Emmy, an Academy Award, an IABM Award and two Cinema Audio Society Awards.
