The DN3030 — Dual-Channel 1/3rd Octave Graphic Equaliser

The Klark Teknik DN3030 is a dual-channel, third-octave graphic equaliser delivering 30 ISO-spaced bands per channel across the full audio spectrum. Built for engineers who need the highest practical resolution from a graphic topology, the DN3030 is the kind of unit that quietly earns its place in the rack and stays there for a decade.

Third-Octave Resolution on Two Channels

Each channel offers a full 30-band fader array tuned to the ISO third-octave centres — the same frequency grid used by real-time analysers, room-correction software, and every serious live-sound rig you’ve ever worked alongside. The bands’ preset Q is set to the value Klark Teknik’s engineers determined produced the most musical response when faders are combined — a non-obvious detail that separates a good graphic from a great one.

Designed for Demanding Stage and Studio Use

Class-leading signal-to-noise, true-bypass relay switching, and conservatively rated linear power supply make the DN3030 a unit that holds its composure under sustained professional load. Two channels in a single 1U enclosure means main-plus-fill or stereo programme EQ without sacrificing rack space.

British Engineering, Studio Heritage

Designed and engineered in Kidderminster, the DN3030 carries the DN-series’ reputation for transparency, predictability, and long-term reliability.
