Klark Teknik DN540

Quad Presence Accenting Compressor with Dynamic Equalisation and Flexible-Channel Linking. DN540 — Quad Presence Accenting Compressor The DN540 packs four channels of creative compression into a single rack unit, with two features that distinguish it from utility compressors: Presence Accenting and Dynamic EQ. The Presence control dynamically accentuates a broad band centred around 5 kHz, restoring high-mid energy that conventional gain reduction often dulls. The Dynamic EQ adds programme-dependent "air" to vocals without the noise floor or pumping artefacts of static high-shelf boosts. Compression Topology Each channel offers rotary Threshold, Ratio, Attack and Release controls. A latching AUTO switch selects RMS-sensing auto mode in place of the default peak-sensing manual mode, with the auto-attack/auto-release timing optimised for transparent compression on programme material. Soft- and hard-knee responses are switchable per channel. Linking and Side-Chain Flexible channel linking allows multiple combinations of side-chain summing, preserving stereo and surround images where conventional fixed-pair links would not. Each channel has an external side-chain input on balanced 1/4" TRS for frequency-conscious compression. A 6-segment gain-reduction and signal-metering LED bargraph tracks each channel. Application Live FOH on vocals, brass and acoustic sources where presence is the deciding factor in mix translation. Touring monitor engineers use the Dynamic EQ to keep wedges intelligible without ear-fatigue from static EQ. Suitable for broadcast, corporate and theatre work alike.
