The DN370 from Klark Teknik is a dual-channel, thirty-band, third-octave graphic equalizer, with long-throw, forty-five millimeter faders, two high- and low-pass filters per channel, and two-notch filters per channel. All production units share a sonic consistency, allowing engineers all over the world to replicate their favorite settings on locally sourced machines.

Aside from the main filters, the unit sports two high- and low-pass filters per channel, and two-notch filters per channel. Low and high frequency limits can thus be set-up for the system, while the notch filters with 18db/octave slopes can be used for precise removal of problem frequencies with minimal effect on the rest of the program material.

The unit utilizes proportional-Q filtering, which varies the "Q" value depending on the depth of either the cut or boost of a particular band. This results in a "smooth" and "musical" response, while still preserving the original source material. Both inputs and outputs are balanced. The internal power supply automatically adjusts itself to various voltages, from 100 to 240VAC.
