    The Klark Teknik DN514 Thank you for selecting the Klark Teknik DN514 Plus Quad Autogate. The unit continues the Klark Teknik tradition of providing superb audio performance, technical accuracy and rugged reliability. Precautions Do not install this unit in a location subjected to excessive heat, dust or mechanical vibration.

  • Page 11: After You Unpack

    If, however, the unit shows any signs of damage, please notify the transportation company without delay. Only you, the consignee, may institute a claim against the carrier for damage during transportation. If necessary, contact your supplier or as a last resort, your Klark Teknik importing agent, who will fully co- operate under such circumstances.

  • Page 13: Introduction

    The Klark Teknik DN514 Plus Quad Auto Gate has been designed to enable the studio or PA engineer to greatly improve the quality of sound achievable, by gating out unwanted background clutter or tape hiss, quickly and simply.

  • Page 15: Front Panel Controls

    Instrument Familiarisation: Front Panel Controls The DN514 Plus QuadAuto Gate consists of four identical channels and a master control section. Threshold determines the level at which the gate will open, variable from -40dBu to +20dBu. A light indicates when the threshold level has been exceeded and the gate is open.

A compatible power cord is supplied with the Mains unit. is located next to the mains inlet connector. Always replace with the correct type and mains fuse rating as indicated on the unit.

    The standard output is unbalanced, but balancing transformers are available and may be retrospectively fitted. Please contact your Klark Teknik representative for more information. The output circuitry is capable of driving a 600 ohm load at a level of +22dBu.
  • Page 18 Side Chain/EXT Key Inputs The electronically balanced Side Chain inputs are on stereo ¼ inch typeAjack sockets, configured: TIP = HOT, RING = COLD, SLEEVE = EARTH. Inserting a mono jack plug will automatically unbalance the input. 1/4” Stereo Jack COLD The sockets are internally normalled so that signal continuity is maintained when there is no jack plug inserted.

  • Page 19: Using The Dn514

    Using the DN514 Even in situations where there are many interacting sound sources we seem to be able to 'tune in' on the sounds we want to hear and reject others. This sometimes known as the 'cocktail party effect' where it is possible to pick out one person's voice even at a distance from many conflicting conversations.

  • Page 20: Setting The Controls

    Setting the Controls The DN514 Plus is a high performance quad noise gate, yet its design makes operation extremely simple. Most important are the Threshold Attack , and Release controls. sets the level at which the gate will open. Turning the control clockwise lowers the threshold level Threshold and allows quieter signals through.

  • Page 21: Side Chain Filter

    Side Chain Filter It is most important for a noise gate to trigger reliably every time the instrument plays or vocalist sings, yet it should not be triggered by the occasional loud sound coming from some other instrument. In a drum kit, for instance, the snare drum and hi-hat cymbals are usually miked and gated separately, yet they may be so close that an almost equal level of signal from both instruments is being picked up by each microphone.

  • Page 22: External Key

    External Key For most applications, the DN514 Plus is triggered by the level of the incoming signal. Sometimes it can be useful to use a different signal to trigger the gate. This is known as an External Key Particularly in the case of drums, a very reliable trigger can be obtained by taping a contact microphone to the shell of the drum and using the clean signal it produces to trigger the gate.

  • Page 23: Synchronisation

    Synchronisation In the case of harmony vocalists or a brass section, the arrangement may be improved by synchronising the release times of the four gates, using the Sync function. With Sync activated, when one gate starts to release, the release times of all the other gates are locked to it : Gate 3 Gate 4 Gate 1...

  • Page 25: Linking To The Console

    Applications: Interface with the console The Klark Teknik DN514 Plus Quad Auto Gate is optimised for use at line level, therefore to gate a microphone, the input to the DN514 Plus has to be taken from the console preferably from the channel insert point send.

  • Page 26: Basic Gating

    Background noise such as outside traffic or air conditioning will be picked up and amplified, causing a considerable reduction in the signal to noise ratio of the system. The solution is to gate each microphone individually using the DN514 Plus Use with Compressors One of the most important applications of a noise gate is the reduction of noise emphasised by the action of compressors.

  • Page 27: Tape Noise

    During mixdown from multi track tape, noise may become obvious. There are two ways in which this can be reduced using the DN514 Plus . The first is to gate the four noisiest tracks, or possibly all twenty four tracks if...

  • Page 28: Advanced Applications

    DN514 Plus. The External Key input is used, with the close mic giving a sharp attack pulse to trigger the gate. The release time is set to give the best sounding decay on the reverb.

  • Page 29: Instrument Synchronisation

    Advanced applications Instrument Synchronisation Sometimes it is necessary to synchronise the attack of two instruments. Often a bass guitar must be made to sync precisely to the regular beat of the bass drum. This can be done by passing the bass guitar through the gate and using the bass drum as the external key.

  • Page 30: Envelope Shaping

    A rhythmic pulse of 8 or 16 notes going all the way through a song is a common musical device. This could be a sequenced synthesiser, but a more interesting method is possible using the DN514 Plus The synth is set up to provide continuous sustained notes (changing according to the harmony of the song), perhaps being processed by a chorus unit before passing through the gate.
