The Klark Teknik DN370 is a dual-channel 1/3 octave (30-band) rackmount graphic equalizer that is designed for the discerning professional who desires uncompromising design. The most important design decision for the DN370 was determining the equalizer response. Proportional-Q equalization, as used on previous Klark Teknik analog graphic equalizers, offers some key advantages over the more numerous Symmetrical-Q equalizers on the market, namely at low amounts of cut or boost the width of the filter is relatively broad and becomes narrower as the amount of boost or cut is increased, giving a more 'focused' response. This differs from a Symmetrical-Q response, which boosts or cuts an increasingly wide band of frequencies, as more of the frequency spectrum is lost when using Symmetrical-Q.
The choice of passive components is critical to ensuring circuit stability and performance. Premium components were chosen to eliminate the non-linear characteristics found in other designs, and to achieve the sonic purity for which Klark Teknik is renowned. Whilst retaining its traditional values, Klark Teknik uses state of the art PCB layout and manufacturing techniques, combined with the use of the latest surface mount components to produce the DN370. These new techniques have made it possible to fit the filter circuits to rear of the fader PCB, with each filter circuit fitting within the footprint of its associated fader. This minimizes the length of connections from each fader to its filter circuit, reducing susceptibility to RFI to a minimum and maximizes stability.
The DN370 has electronically-balanced input and output circuits to preserve the highest signal integrity. The inputs have excellent common-mode rejection and the outputs have high-drive capability to cope with long cable runs. Although equalizers are more generally used on console inserts, the DN370 is fully capable of being used in-line with cables running the long distances between the Front Of House mix position, the main stage and the delay towers in festival PA systems. Transformer balancing is available as an additional option on both the inputs and outputs.
