Cedar DNS 4 Dialogue Noise Suppressor
The Cedar DNS 4, a dialogue noise suppressor, removes traffic noise, air conditioning, wind, rain, babble, and general background noise from four channels of audio.
It also helps compensate for unfavorable acoustics and poor microphone placement, and it suppresses excessive reverberation. To set it up, switch on the Learn function, which identifies and adapts to the background noise, then adjust the amount of attenuation you want. With near-zero latency and no loss of lip-sync, it suits location recording, live-to-air broadcasting, studio work, and live sound in theaters, concert halls, conference venues, and places of worship. It also refreshes sound libraries and enhances speech for audio forensic investigations.
The DNS 4 takes up little more space than the DNS 2 and doubles the number of channels. It has a Hirose HR-10 power input and mini-XLRs for many of its connections. It fits in a pocket or equipment bag and runs on 12 V power, with an AC adapter in the box. It has analog line inputs, ultra low-noise microphone inputs with optional 48 V phantom power, AES3/AES11 digital inputs, and both analog and digital outputs. The analog inputs sit on the left side, the digital connections and analog outputs sit on the right side, and the rear is blank.
