5 l abc Intr oduction Compression, expansion, limiting and peak clipping are four of the most valuable techniques available to the sound engineer . Not only can they solve many problems that can arise in day to day work, creative possibilities exist in abundance. The Klark T eknik DN500 Plus Dual Compressor/Limiter/Expander integrates all of these [...]

7 l abc Instrument Familiarisation: Fr ont Panel Controls The DN500 Plus Dual Compressor/Limiter/Expander consists of two identical channels, each with separate Compressor , Expander and Limiter sections. 1. determines the level above which gain reduction (compression) will take place, variable from +20dBu down to -30dBu. The Gain Reduction light b[...]

l abc Expander Threshold Ratio 10. determines the level below which gain reduction will take place, variable from 20dBu down to -40dBu. Gain reduction BELOW a threshold level constitutes dynamic range EXP ANSION. The Gain Reduction light bar graph meter indicates in decibels by how much the signal is expanded at any instant. 1 1. sets the degree of[...]

l abc Audio Connections 11 Input Output The input circuit is a transformerless, electronically balanced design which achieves a symmetry of better than- 50dB from 20Hz to 10kHz. If transformer balancing of the input is required, this must be specified at the time of order . It is not retrofittable. The standard output is unbalanced, but balancing t[...]

Side Chain/EXT Key Inputs Balanced Circuits The electronically balanced Side Chain inputs are on stereo ¼ inch type A jack sockets, configured: TIP = HOT , RING = COLD, SLEEVE = EAR TH. Inserting a mono jack plug will automatically unbalance the input. The sockets are internally normalled so that signal continuity is maintained when there is no ja[...]

13 l abc Using the DN500 The natural sounds of life have an extremely wide dynamic range, from the result of a falling leaf to the roar of a jet engine on take off. The human ear has an automatic gain control which enables it to accommodate all of these sounds from the threshold of hearing to close to the threshold of pain, a dynamic range of appro[...]

14 l abc One of the principal uses of compression is the control of level in vocals. Many singers train for years to achieve the degree of breath control necessary for an even tone and expressive performance. Other vocalists rely on an instinctive voice production technique, which may need help in the studio to maintain a consistent level, and resu[...]

l abc 16 W ith a soft knee, signals which only just exceed the threshold level are compressed at a low ratio, the ratio increasing the higher the signal level. sets the time the Compressor takes to respond once the threshold has been exceeded. Attack may be set so that the initial transient of the instrument passes through unaltered, or set to a fa[...]

l abc 17 Expansion may be used to increase the dynamic range of a signal : of a performance lacking life and vigour , or of a previously over compressed recording. Alternatively , expansion can be used to reduce noise, either subtly and undetectably , or with the harder action of a noise gate. The unprocessed signal has a fairly narrow dynamic rang[...]

l abc 18 Threshold Ratio Attack Release Gain sets the level below which expansion takes place. Signals above the threshold will remain unaltered. T urning the control anticlockwise raises the threshold level and allows more of the signal to be expanded. A low threshold would be used to reduce noise, a higher threshold to increase the dynamic range [...]

19 l abc Limiting The Limiter acts as a last check on signal level. If the level goes over the threshold, fast acting, high ratio compression is applied to bring it back within bounds. If absolute control over peak levels is required, a Peak Clipper may be switched in, acting in effect as a compressor with a ratio of infinity:1 and an instantaneous[...]

20 l abc Compr ession, Expansion and Limiting The act of compressing a signal inevitably causes an increase in noise level. Compression reduces peak levels; gain make up restores the overall level, and in the process increases the level of any background noise that the signal contains. Almost always, when compression is used, the Expander section o[...]

21 l abc The Klark T eknik DN500 Plus Dual Compressor/Limiter/Expander is optimised for use at line level, therefore to process the signal from a microphone, the input to the DN500 Plus has to be taken from the console preferably from the channel insert point send. The output from the DN500 Plus comes back to the channel insert return. By connectin[...]

22 l abc Applications: Side chain inputs Each channel of the DN500 Plus has two inputs, one for the Compressor and one for the Expander . In normal use, the amount of compression or expansion is related to the dynamics of the input signal. The Side Chain allows the signal passing through the unit to be controlled by the dynamics of another separate[...]

l abc 23 Applications: De-essing De-essing is an important compression technique using the Side Chain. Many singers have high level sibilants 'sss' sounds which detract from their performance. Equalising the signal will reduce the sibilants, but also make the overall vocal sound dull. The sibilants can be selectively removed by compressin[...]
