Page 4: Introduction
So we designed the DNS2000… The DNS2000 is a combination of a rackmount unit that provides audio I/O and nearly 200MFLOPS of processing power, plus remote control software for your Pro Tools host system. -
Page 5: Host System Requirements
HOST SYSTEM REQUIREMENTS Macintosh OS-X users: The DNS2000 should be used with Pro Tools version 6 or later. Any Macintosh with a free USB port running Mac OS-X and a suitable version of Pro Tools will support the OS-X version of the DNS2000 Remote Control Software and processor unit. -
Page 6: Safety Instructions
Mounting and ventilation You should place the DNS2000 on a flat, stable surface or mount it in a standard 19” equipment rack. Use the supplied rubber feet to avoid scratching the surface, or the rackmounting accessories, as appropriate. -
Page 7: Setting Up The Dns2000
Digital SPDIF format Digital AES/EBU format Note: The processor will lock onto the first input that provides a valid clock. The DNS2000 is not affected by channel status data. It will echo any such data directly to the outputs. Page 7... -
Page 8: The Remote Control Software
It is not necessary to restart your Macintosh after transferring these files if you are loading the DNS2000 Remote Control Software for the first time. However, you will need to perform a restart after loading a new version of the Remote Control Software. -

OS9.xx error screen OS-X error screen If you have attached the DNS2000 to the Pro Tools system using the USB cable, and if you have correctly connected the audio signal leads to the DNS2000, you should now be ready to process audio. -
Page 10: Software Controls
Low + Mid 20Hz - 6kHz Mid + High 200Hz - 18kHz Full Range 20Hz - 18kHz Selecting any of these ranges concentrates all of the filters within the DNS2000’s filter bank across that part of the audio spectrum. Page 10... -
Page 11: Generic Pro Tools Plug-In Controls
Audio I/O Status When a DNS2000 processor is connected and selected, the drop-down list will report the audio input to which the DNS2000 is locked, the sample rate of the incoming audio, and whether that sample rate lies more than 10% outside the accepted 44.1kHz and 48kHz standards. -
Page 12: Hardware Indicators
If the red ‘0’ LED lights continuously for about one second, this indicates input clipping. Note: 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 13: Range Leds - Channel 1 & Channel 2
Range LEDs - Channel 1 & Channel 2 The three LEDs Low, Mid and High indicate which range(s) is/are selected for processing. Note: These LEDs will flash a number of times when a given processor and channel are selected from the Remote Control Software. When used in a multi-processor environment, this gives a direct visual indication of the relationship between the Software and each processor. -
Page 14: Tutorial
You can do this, for example, by using an insert point within the Pro Tools mixer. The following tutorial illustrates one way to use the DNS2000. It may not be the way that you choose to operate it for all jobs, but it will get you started…... -
Page 15: Range Selector
OS9.xx users only: The Range LEDs on the DNS2000 rackmount unit will flash a number of times when a given processor and channel are selected from the Remote Control Software. When used in a multi-processor environment, this gives a direct visual indication of the relationship between the Software and each processor. -
Page 16: Case Studies
CASE STUDIES The following case studies describe just three of the ways in which you can use the DNS2000. You can apply the DNS2000 equally to recorded signals and to ‘live’ signals at the point of recording or transmission. Suppressing traffic noise and other ambient sound... - Page 17 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 18: 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 many generations old. First, identify the frequency range(s) in which the noise lies. -
Page 19: Suppressing Excessive Reverberation
Second, set the Band Gain controls. You should set all six Band Gain controls to -24dB. This will ensure that (if the Level is set correctly) the DNS2000 applies maximum suppression to the tails of the sound. Third, optimise the Level control. -
