Klark Teknik DN504Plus Compressor - Limiter

KLARK DN504plus Details ^top

The revised DN500 Plus series utilises a new ‘THAT's' chip which features lower distortion, improved dynamic range and faster slew rate. We've updated the cosmetics too, bringing them into the new KT ‘family look'.

The DN500 Plus is our dual compressor / limiter / expander which is characterised by its extremely quiet operation, typically >2dB quieter than any comparable product. This alone has made it a broadcast-industry standard for many years. The two channels are linkable for true stereo operation, and both the compressor and expander sections are fitted with their own sidechain inputs.

The DN504 Plus Quad Compressor has enjoyed hugely increased popularity in recent years, due to the ever expanding use of in-ear monitor systems. This is because the unit can be configured into two stereo pairs, has all the superlative audio performance of the DN500 Plus, and fits two sets of stereo compression into just one rack space. This configuration also makes it extremely cost effective.
