DN530 Operator Manual 1 Chapter 1: Introduction Thank you for purchasing a Klark Teknik DN 530 Creative Quad Gate. The DN530 is a user-friendly, high-performance, four-channe l (quad) analogue gate designed for live sound reinforcement with applications in both front-of-house and monitoring situations. Other possible areas for use include broadcast[...]

Chapter 1: Introduction DN530 2 Operator Manual Applications The DN530 provides a quality, cost effectiv e and compact gating un it presented in a traditional 1U quad channel format. This make s it suited to applications where space is limited and is ideal for small touring public address (PA) rigs where the four channels are enough to cover a smal[...]

Features DN530 Operator Manual 3 Features The DN530 has the following features: • The gate action has rock solid triggering. • Advanced band pass sidechain filter , which is easy to set up. • Separate (daisy-chainable) solo bus that a llows tuning of the sidechain filter , ev en during the performance. • Attack is exponential, so that it ca[...]

DN530 Operator Manual 5 Chapter 2: What Is A Gate? The natural sounds of everyday life, which can be caused by anything from, say, the falling of a leaf to the roar of a jet engine, vary extremely widely in sound level. This variance is known as the ‘dynamic range’ and is the difference — expressed in decibels (dB) — between the loudest and[...]

Even in situations where there are many so un d so ur ce s , w e se em t o b e ab le t o t un e in to t he s ou nd s we wa n t t o he ar a nd r ej ec t other[...]

Other uses of gating DN530 Operator Manual 7 Other uses of gating Gates were originally devised to reduce noise in the silent passages of a music programme, especially during the process of multi-track recording on analogue tape. Although they are still used for reducing noise, many other uses and crea tive applications have been found for them ove[...]

Inserting a mono jack plug will automatica lly unbalance the input. The following diagram shows the sidechain input connection details. The 1/4” TRS co nnector wiring details are as follows: Tip R[...]

Chapter 3: Getting Started DN530 12 Operator Manual Connecting to un balanced eq uipment Ideally, you will be making the best use of the DN530’s low-noise high-headroom balanced inputs by connecting to similarly balanced equipment. However, if you do have to connect to unbalanced devices, the following wiring is recommended for best results (see [...]

DN530 Operator Manual 13 Chapter 4: Front Panel The front panel of the DN530 has four m ain channel sections, each containing a number of control knobs, pushbuttons and LEDs. Each main chann el section is divided into a gate section and a sidechain sec tion. All of the switches on the front panel are of the latching pushbutton type and have two pos[...]

Chapter 4: Front Panel DN530 14 Operator Manual Gate section The gate section houses six gate parameter control knobs, bypass and duck switches, and a set of six metering LEDs. For more information on the gate controls and their uses, see Chapter 6 "Gate Control Functions" on page 19. Item Type Label Function 1 Control knob ATTACK Adjusts[...]

Gate section DN530 Operator Manual 15 Metering The key to successful DN530 operation is to know when signals are above or below threshold. This is especially true if the a ccent feature is used with low range settings or with no gating action at all. This style of metering provides an intuitive moving LED indication that ramps up and down as the si[...]

Chapter 4: Front Panel DN530 16 Operator Manual Sidechain section The signals that feed the gate’s sidechain ar e called the "sidechain". A band pass filter is provided that acts on the sidechain signals. The sidechain section for each channel can be broadly divided into two areas: filter and solo. The filter section comprises the FREQU[...]

DN530 Operator Manual 17 Chapter 5: Rear Panel The rear panel of the DN530 (shown below) has three main connector sections: mains input, solo bus and the four channels. Mains input The mains input section has a mains IEC socket, below which is a fuse drawer. Printed to the right are mains supply voltage and fuse details. The mains input is an auto-[...]

Chapter 5: Rear Panel DN530 18 Operator Manual Solo bus The solo bus section comprises an input and an output XLR chassis connector. These are connected to an external monitor input, such as a mixing console, or they can be daisy-chained to other units being monitored (see Figure 3, “Daisy-chaining the DN530s (solo bus),” on page 23). Solo conn[...]

DN530 Operator Manual 19 Chapter 6: Gate Control Functions This chapter gives details of the control functions of the DN530 gate. Attack Attack is the time taken for the gate to open after an over threshold signal. The shape of the attack is fixed and has be en carefu lly tailored to produce a transparent gating action. Hold Minimises chattering in[...]

Chapter 6: Gate Control Functions DN530 20 Operator Manual The advantage of generating the effect in this way is that it is much more straightforward to set up and has the added benefit that the attack control operates to change the sonic character of the accent as we ll as the gate. This allows a more precise tailoring of the sound produced — ch[...]

DN530 Operator Manual 21 Chapter 7: Using The Gate The DN530 is a gate processor that utilises pre mium quality, high precision components to achieve a high degree of accuracy and control. The DN530 has been designed primarily for creative use as front of house (F OH) or mo nitor. However, it is just as effective when used in the studio while broad[...]

Soloing DN530 Operator Manual 23 Soloing You can monitor the sidechain during the performance using the dedicated solo output. To do this, connect the solo output to a sp are input channel, line return, effects return etc., on your mixing console. Enabling an y solo pushbutton will route that processor’s sidechain monitor to the solo output, allo[...]

Chapter 7: Using The Gate DN530 24 Operator Manual Interfacing with the console The DN530 is optimised for use at line level, therefore to gate a mic, the input to the DN530 has to be taken from th e console, pref erably from the channel insert point send. The output from the DN530 comes back to th e channel insert return. By connecting the DN530 a[...]

Using gates with compressors DN530 Operator Manual 25 Using gates with compressors One of the most important applications of a noise gate is the reduction of noise emphasised by the action of compressors. When any signal is compressed, the highest levels are reduced, but the lowest noise levels remain the same. This effectively decreases the signal[...]

Chapter 7: Using The Gate DN530 26 Operator Manual Instrument synchronisation Sometimes it is necessary to synchronise the attack of two instruments. Often a bass guitar must be made to synchronise 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 sid[...]

DN530 Operator Manual 27 Appendix A: Application Notes As most dynamics processing is a matter of personal taste and preference, these application notes are provided as a guide on ly. Experimenting in unconventional areas can often yield interesting and useful results. Always remember, be creative with your DN530 — and have fun! When using noise [...]

Application Notes DN530 28 Operator Manual If the gate is being used creatively, the e ffect of the gate opening transition can be accentuated. This is particularly useful on drums, improving definition and punch. The accent effect is totally independent of the range control, so it is possible to reduce the range very low or even off (0dB) and stil[...]

Envelope shaping DN530 Operator Manual 29 Envelope shaping A rhythmic pulse of 8th or 16th 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 DN530. The synthesiser is set up to provide continuous sustained notes (changing according to the har[...]

Application Notes DN530 30 Operator Manual Chatter Chatter can normally be eliminated by increa sing the hold time, but this may allow the gate to stay open longer than is desirable. Adding hysteresis to the threshold control helps enormously and allows hold times to be reduced without signal chatter. The DN530 has 4dB of i-TS hysteresis built in, [...]

Noise enhancement DN530 Operator Manual 31 Noise enhancement We all have the ability to block out constant background noises and often using a gate to eliminate background noises altogether de feats this mechanism. This tends to draw our attention to the noise when the gate opens. Typically, adjusting the gate range down to 10dB or 15dB produces re[...]
