Small-Form DNS4

The new CEDAR dialogue noise suppressor.


12 September 2022

Cedar Audio has introduced its DNS 4, the latest and 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.

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 unfavourable 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.

It’s incredibly fast and simple to use. The DNS algorithm requires nothing more than being switched to the ‘Learn’ function that identifies and adapts to the background noise, which then adjusts the amount of noise attenuation required. Despite its convenient size — able to be slipped it into a pocket or equipment bag — it offers analogue line inputs, ultra low-noise microphone inputs (48V phantom power), AES3/AES11 digital inputs, and analogue and digital outputs. It also runs on 12V power for flexibility of use, so can be used in a field, or in a studio or edit suite.

Retaining the near-zero latency of its predecessors, the DNS 4 is suitable for use in all situations; in studios, location recording, live-to-air broadcasting, and live sound in venues such as theatres, concert halls, conferences venues and places of worship. The DNS 4 is not a replacement for any existing Cedar product, it has been designed with customer feedback in mind. The product fills a hole in the existing range, and complements the DNS 2, and DNS 8D by appealing to customers who require more than two channels of DNS in a portable enclosure, rather than a rackmount package.
