DN540 Operator Manual 1 Chapter 1: Introduction Thank you for purchasing a Klark Teknik DN540 Creative Quad Compressor. The DN540 is a user-friendly, high-performance , four-channel (quad) analogue co.
Chapter 1: Introduction DN540 2 Operator Manual The presence control progressively reduces compression in the 5kHz region. Attenuation depth and input level meters are provided, plus a switch that changes the output level meter to mo nitor the input signals.
Features DN540 Operator Manual 3 Features The DN540 has the following features: • Great sounding compressor that provides good audio performance at extremely low noise and distortion levels. • Easy to use basic compressor , requiring minimum set up to produce excellent results.
Chapter 1: Introduction DN540 4 Operator Manual.
DN540 Operator Manual 5 Chapter 2: What Is A Compressor? 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.
Chapter 2: What Is A Compressor? DN540 6 Operator Manual The level of a vocal may vary widely. As shown in the typical example in Figure 1 “Compression - signal level graphs”, the unprocessed signal has a large dynamic range between the highest and lowest levels.
Unwanted side effects DN540 Operator Manual 7 Providing controls for threshold, attack, re lease and ratio, and providing responsive metering can go along way towards helping with suitable parameter set up for any signal source, such that most of the negative effects above can be reduced or eliminated.

DN540 Operator Manual 9 Chapter 3: Getting Started Observing the IMPORTANT SAFETY INSTRUCTIO NS at the front of the manual and the guidelines in "Precautions" on page vii, carry out the following to get your DN540 unit fully operational. Unpacking Carefully unpack your DN540 equipment package.
Chapter 3: Getting Started DN540 10 Operator Manual Connecting the power cable Making sure that the mains power at the po wer outlet is off, connect the mains cable supplied with your DN540 to the mains power outlet and then to the mains socket at the rear of your unit.
Connecting the audio cables DN540 Operator Manual 11 Sidechain inputs The electronically balanced sidechain inputs are on stereo 1/4” TRS connectors. Inserting a mono jack plug will automatica lly unbalance the input. The following diagram shows the sidechain input connection details.
Chapter 3: Getting Started DN540 12 Operator Manual Connecting to un balanced equip ment Ideally, you will be making the best use of the DN540’s low-noise high-headroom balanced inputs by connecting to similarly balanced equipment.
DN540 Operator Manual 13 Chapter 4: Front Panel Overview The front panel of the DN540 has four m ain channel sections, each containing a number of control knobs, pushbuttons and LEDs. All of the switches on the front panel are of the latching pushbutton type and have two positions, in (on) and out (off ).
Chapter 4: Front Panel DN540 14 Operator Manual Compressor section Each compressor section houses six compressor parameter control knobs, a bypass switch and a hard knee switch, and two sets of six-LED meters (attenuation and level).
Switch section DN540 Operator Manual 15 Switch section The switch section has four switches for: changing the compressor mode; switching the signal level meter from output signal to input signal; external sidechain; and channel linking. 11 LED (red) Not applicable On/off status indicator for the BYPASS pushbutton.
Chapter 4: Front Panel DN540 16 Operator Manual.
DN540 Operator Manual 17 Chapter 5: Rear Panel The rear panel of the DN540 (shown below) has a mains input section and four channel connector sections. Note: Although the rear panel of the DN540 has cutouts for two solo bus connectors, these are unused on this unit and are therefore blanked off.

DN540 Operator Manual 19 Chapter 6: Compressor Control Functions This chapter explains the control functions of the DN540 compressor. Attack Attack is the time it takes for the compre ssor to respond once the threshold has been exceeded.
Chapter 6: Compressor Control Functions DN540 20 Operator Manual Release time plays a very important role in compression. During periods of high signal level, gain is reduced. When the signal level falls below the threshold, the gain will increase at a rate determined by the RELEASE control knob.
Threshold DN540 Operator Manual 21 Threshold The compression threshold is the point at wh ich the compressor begins to operate. Signals that exceed this point, that is, go over threshold , will be affected by compressor actions.
Chapter 6: Compressor Control Functions DN540 22 Operator Manual Soft knee and hard knee The point where the slope of the compressor curve changes is known as the “knee”. The DN540 can be set to operate as either a soft knee or hard knee compressor; the effects of both can be seen in Figu re 5 “Soft knee and hard knee graphs”.
DN540 Operator Manual 23 Chapter 7: Using The Compressor The DN540 is a dynamics processor that utilises premium quality, high precision components to achieve a high degree of accuracy and control. Th e DN540 has been designed primarily for creative use as front of house (FOH) or monitor.
Chapter 7: Using The Compressor DN540 24 Operator Manual Manual mode with hard knee (linear peak) With the HARD pushbutton switched on, the compressor is peak sensing with manually adjustable linear attack and second order release envelope characteristics.
Modes of opera tion DN540 Operator Manual 25 Figure 6: Compression - limiting signal level graphs If a compression effect is required together with limiting of high level transients, two channels of the DN540 may be cascaded.
Chapter 7: Using The Compressor DN540 26 Operator Manual Simple compression (auto mode) For many every day compression jobs an RMS compressor with automatic time constant set up (attack and release) is the best solution, providing quick and easy set up.
Stereo and multiple ch annel operation - linking DN540 Operator Manual 27 Stereo and multiple channel operation - linking Using the intermediate LINK switches (in channels 1, 2 and 3), you can link to the adjacent channel on the right for stereo or multi-channel operation.
Chapter 7: Using The Compressor DN540 28 Operator Manual When LINK is switched on, the compressor sidechains of the linked channels are combined by a true power law summer such that a single source panned from left to right will not change the compression le vels that have been applied to it.
DN540 Operator Manual 29 Appendix A: Application Notes The compressor of the DN540 can perform various compression styles for different applications. Drums and percussive instruments Drums require a slow attack time to thicken the sou nd. Try the compressor in manual mode with high ratios, slow attack, medium release and soft knee.
Application Notes DN540 30 Operator Manual compressor relaxes there is no gain re du ction — but the upper frequency boost remains, increasing noise and making microphonic feedback much more likely . The DN540’s presence accentuation corrects the tendency for dull sound during compression, without changing the sound of un compressed signals.
