Introduction 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 Teknik DN500 Plus Dual Compressor/Limiter/Expander integrates all of these processes into a single, compact, rack mounting unit with two channel operation. Complete dynamic control over gain is the result, and also control over pro

Compressor 1. Threshold determines the level above which gain reduction (compression) will take place, variable from +20dBu down to -30dBu. The Gain Reduction light bar graph meter indicates in decibels by how much the signal is compressed at any instant.

Expander 10. Threshold 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 EXPANSION. The Gain Reduction light bar graph meter indicates in decibels by how much the signal is expanded at any instant. 11. Ratio sets the degree of expansion applied below the threshold level, variable from 1:1 to 25:1. A ratio of 1:1 corresponds to zero expansion : Signal In = Signal Out. Aratio of

Audio Connections Input 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. Output 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

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 HOT COLD GND The sockets are internally normalled so that signal continuity is maintained when there is no jack plug inserted. If the unit is wired to a patchbay, then normalling must be carried out at the patchbay. Balanced Circuits Transformer o
