    Pro Tools, both on the Mac and PC. Today, the DNS3000 offers the manual control of the DNS1000 and its successor, the DNS1500, the Pro Tools integration of the DNS2000, plus an internal system of scenes, memories, and (when slaved to timecode) snapshot automation with moving faders.

  • Page 7: Safety Instructions

    ■ Mounting and ventilation The DNS3000 should be placed on a placed on a flat, stable surface. Do not subject it to strong sunlight, excessive dust, mechanical vibration or periodic shocks. It is not susceptible to heat build-up, but should be installed away from heat sources such as radiators, and audio devices such as amplifiers that produce large amounts of heat.

  • Page 8: Getting Started

    Mains power is provided using the standard IEC power cord supplied with the DNS3000. Mains power is switched on and off using the switch on the rear panel. However, you may normally leave this switched on and use the power switch on the top panel to turn the DNS3000 on and off.

  • Page 9: Connections

    The standards are: Digital SPDIF format You should connect the SPDIF output from your source to the SPDIF input of the DNS3000 using a single cable terminated with an RCA (or 'phono') plug. The SPDIF output of the DNS3000 should be connected to the SPDIF input of a recording device or external DAC.

  • Page 10: Front Panel Indicators And Controls

    Power ■ Power on/off button Press this to switch the DNS3000 on, and hold it to switch the unit off. If you switch off using the rear panel switch without first powering down using the soft power button, you risk corrupting the internal memory of the unit.
  • Page 11 The Range Selectors concentrate the unit’s activity into the desired part of the audio spectrum. ■ Level control The Level control tells the DNS3000 how much noise is present in the input signal. ■ Band Gain controls The Band Gain controls determine the maximum amount of processing that the DNS3000 will apply in each band.

  • Page 12: Stand-Alone Operation

    To select Low + Mid or Mid + High, press the appropriate two buttons simultaneously or in quick succession. To select Full Range, press the Low and High buttons simultaneously or in quick succession. Selecting a range concentrates all of the filters within the DNS3000’s filter bank across that part of the audio spectrum. Level control Your next job will be to identify the noise level of the audio.
  • Page 13 You can route the input directly to the output by pressing the Bypass button. This allows you to switch off all processing, regardless of any other settings, either on the DNS3000 itself (including the in-built scenes and automation) or obtained by remote control. The signal latency is not affected by the Bypass state.

  • Page 14: Case Studies And Tutorials

    CEDAR DNS3000 dialogue noise suppressor Case studies and tutorials The following case studies describe just three of the ways in which you can use the DNS3000. You can apply the DNS3000 equally to recorded signals and to ‘live’ signals at the point of recording or transmission.
  • Page 15 If this proves difficult, you can return the Band Gain controls to -24dB for this stage. The DNS3000 takes a short period to ‘settle’ after moving the Level control (especially in the lower ranges) so you should not adjust it rapidly.

  • Page 16: Case 2: Suppressing Tape Hiss

    CEDAR DNS3000 dialogue noise suppressor Case 2: Suppressing tape hiss The DNS3000 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.

  • Page 17: Case 3. Suppressing Excessive Reverberation

    CEDAR DNS3000 dialogue noise suppressor Case 3. Suppressing excessive reverberation In many situations, the DNS3000 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.

  • Page 18: Advanced Use

    CEDAR DNS3000 dialogue noise suppressor Advanced use The following section of the manual describes how to set up the DNS3000 and how to use its advanced features, including its presets, snapshots and timecode facilities. Front Page The front page shows the process settings for both channels, allowing you to see the complete setup without flipping between the channels using the CHAN1 and CHAN2 buttons.

You may need to consult your network administrator for help in connecting the DNS3000 to your network. If required, the unit MAC address is printed on the rear of the unit. When connected...
  • Page 21 CEDAR DNS3000 dialogue noise suppressor Timecode Setup page This page allows you to select automatic or manual selection of the timecode format. Toggle between the two states using the spinwheel when Mode is selected. Auto If automatic, the format field shows the current format for information only. The format can only be detected while the timecode input is active and playing.

  • Page 22: Using Scenes

    Snapshots The system of snapshots provided by the DNS3000 allows you to automate the loading of process parameters against an external timecode source. This is done using the Snapshot Manager page.
  • Page 23 CEDAR DNS3000 dialogue noise suppressor Preset Manager Page This provides access to 100 storage slots for presets. ■ Recall: recalls the selected preset. ■ Store: stores the current settings in the selected preset and opens the Name Editor page ■ Delete: deletes the selected preset.
  • Page 24 CEDAR DNS3000 dialogue noise suppressor Snapshot Manager Page STOP and PLAY There are two automation states: STOP and PLAY. The current state is displayed alongside the incoming timecode in the top right-hand corner of the display. Switch between states using the soft button labelled either Play or Stop (as applicable). In PLAY mode, snapshots are automatically recalled against the incoming timecode, and some snapshot creation/deletion/editing functions (see below) are disabled.
  • Page 25 CEDAR DNS3000 dialogue noise suppressor Delete Snapshot? page This page allows you to delete the selected snapshot or all snapshots. You will be asked to confirm this operation. Snapshot Editor Page This page allows you to change the name and process settings of the selected snapshot, and the time at which it occurs.

  • Page 27: Remote Control

    CEDAR DNS3000 dialogue noise suppressor Remote Control The DNS3000 is supplied with remote control software (RCS) that allows you to control it from a Mac- or PC- based Pro Tools™ system. When used in this way, there is an Ethernet control connection between the DNS and its host.

  • Page 28: Installing The Dns Software

    DNS3000 Network Scanner The Network Scanner must be run in order to allocate which DNS3000 units on an Ethernet network are available to a given instance of the RCS. Until it is run, the RCS will only be able to see DNS2000 units connected by USB.
  • Page 29 Scan IP Allows the user to enter the IP address of a DNS3000 not on a local network, or that is on such a large local network that 'Scan All' would take too long to find it. You may then make the unit available from this Mac/PC by selecting it and moving it to the 'Registered DNS Units' list –...

    Remote Control Software. It performs no audio processing. To process an audio stream you must route it via the DNS3000 itself using the AES/EBU or SPDIF I/O. You can do this, for example, by using an insert point within the Pro Tools mixer.
  • Page 31 - together with the Pro Tools Bypass control - may be automated in standard Pro Tools fashion. To use the RCS in ‘Touch’ mode, the user must select touch mode on the DNS3000 as well as on Pro Tools, otherwise ‘fighting’ on the unit's faders can occur. The relevant faders will be shown in pink when touch mode is selected.
