Klark Teknik DN410 Parametric Equalizer

These units show signs of heavy wear but are in good working condition.

The Klark-Teknik DN410 is a dual channel, 2 x 5 band parametric equalizer designed for precise tonal shaping in live sound, studio, and installed audio systems. Each band lets you target any frequency from 20Hz to 20kHz with up to 15dB of boost or 25dB of cut, plus adjustable filter bandwidths from less than 1/12 octave to more than 2 octaves, making it well-suited for everything from narrow feedback control to broader musical EQ moves.

Precision EQ Control for Mixing and System Tuning

With two independent channels, the DN410 fits naturally on stereo program material, dual mono sources, or across subgroups and sends. The combination of wide frequency coverage and continuously variable bandwidth makes it a practical choice for correcting room or speaker response, carving space in dense mixes, and managing problematic resonances without overprocessing the rest of the signal.
