Connectivity The DNS2000 can be used with both Pro Tools (Mac) and Pro Tools (PC) systems. -

Range Selectors The Range Selectors concentrate the unit’s activity into the desired part of the audio spectrum. Selecting any of these ranges concentrates all of the filters within the DNS2000’s filter bank across that part of the audio spectrum. Range... -
Page 17: Device Selection
The DNS2000 divides a signal into a large number of well-defined bands. Sophisticated digital filters analyse each of these bands and suppress the noise independently in each. The innovative design of this filter bank allows you to adjust the DNS2000 using relatively few controls. - Page 18 If the DNS Control System has not connected successfully with the DNS2000 processing engine the following status messages may occur: Message Explanation No unit connected No DNS2000 hardware has been detected. Unknown error Another error has occurred. Further investigation will be required.

Channel 2. If the red ‘0’ LED lights continuously for about one second, this indicates input clipping. The DNS2000 is capable of applying gain to the signal, so the absence of input clipping does not guarantee the absence of output clipping. -
Page 20: Use
Control System software is precisely what it claims to be: a control system. It performs no audio processing. To process an audio stream you must route it via the DNS2000 rackmount unit. You can do this, for example, by using an insert point within the Pro Tools mixer. -
Page 21: Level Control
Tutorials The following three tutorials illustrate ways to use the DNS2000. They may not be the ways that you choose to operate it for all jobs, but they will get you started. - 17 -... -
Page 22: Suppressing Traffic Noise And Other Ambient Sound
If this proves difficult, you can return the Band Gain controls to -24dB for this stage. The DNS2000 takes a short period to settle after moving the Level control (especially in the lower ranges) so you should not adjust it rapidly. - Page 23 Third, refine the Band Gain controls for optimum suppression. Set all six Band Gain controls to 0dB. Now increase and decrease the gain in each band separately while listening to the effect that each has on the noise. This will identify the bands that contain the majority of the noise.

Page 24: Suppressing Tape Hiss
SUPPRESSING TAPE HISS The DNS2000 can suppress the tape hiss that mars many older recordings. It will also improve the signal/noise ratio of dialogue tapes that have been poorly copied as well as those that are several generations old. First, identify the frequency range(s) in which the noise lies. -
Page 25: Suppressing Excessive Reverberation
SUPPRESSING EXCESSIVE REVERBERATION In many situations, the DNS2000 can suppress excessive reverberation. This can be useful in TV production when you need to match the audio from a large recording studio or soundstage to visual images set in a small room or other enclosed space. Suppressing reverberation can also be beneficial in increasing the intelligibility of poor dialogue recordings. -
