DISC Klark Teknik DN370 Dual 30-Band Analogue Graphic Equaliser

Full Description

Enhanced Proportional-Q Equalisation

The DN370 boasts Klark Teknik's enhanced Proportional-Q equalisation design, providing a vast range of advantages in comparison to Constant-Q equalisers. The Proportional-Q response of the DN370 preserves more musical content, and minimises interactions between adjacent frequency bands. It works by providing a broad filter width at low amounts of cut or boost, whilst becoming progressively narrower as you increase the cut or boost amounts. This allows you to attenuate problematic frequencies with ease, and provides you with a much more focused response. You don't have to worry about the unnecessary loss of larger areas of the frequency spectrum or frequency response ripple as you would with Constant-Q equalisation.

Comprehensive and Intuitive Filter Control

Precise corrective control. The Klark Teknik DN370 is equipped with a selection of push-button control knobs for its continuously swept filters, enabling you to switch your filter in and out without having to change the frequency setting. You can view your control knob settings with ease thanks to integrated LED rings.

The DN370 features a 12dB/octave high-pass filter, with an adjustable range of 20Hz to 500Hz. This filter is perfect for removing unwanted low frequencies from your signal. There is also a 12dB/oct low-pass filter, with a range of 2kHz to 20kHz, allowing you to adjust the upper frequency response of your signal to match your desired system.

There are two notch filters that feature frequency ranges that overlap. The first features a range of 20Hz to 2kHz, whilst the second ranges from 200Hz to 20kHz. These filters allow you to remove unwanted resonance and feedback, whilst simultaneously providing rapid adjustability of the frequencies between the faders. Plus, thanks to their overlapping ranges, when using the notch filters in combination with the DN370's EQ bands, you can achieve up to 45dB of attenuation. Plus, with a gain control for each channel ranging from -∞ to +6dB, you can quickly and easily mute your signal path when unexpected feedback occurs.

Oil-Damped High-Resolution 45mm Faders

The DN370 gives you complete control over thirty independent frequency bands for each of the unit's two channels. Each band features a centre-detented long-throw 45mm precision oil-damped fader, giving you phenomenal control over each band's +/-12dB range. You can even take advantage of a +/-6dB range for more precise fine-tuning of each band. Channel Bypass and GEQ Range selection switches provide you with quick and easy configuration options, whilst each fader is equipped with a protective cover to prevent damage from dirt and dust in demanding environments.

Rugged and Reliable Construction

A rugged steel 3U rackmount chassis, electronically-balanced I/Os, and an auto-ranging universal switch-mode power supply. The Klark Teknik DN370 is the ideal choice for live-sound equalisation. Built to withstand demanding environments, the DN370 features premium Neutrik and Phoenix connectors for outstanding connection reliability. The inputs boast exceptional CMRR, whilst the outputs feature high-drive capabilities to maintain the integrity of your signal across long cable runs. The DN370 can be used as a console insert, or in-line, providing you with versatile options for use in a vast range of situations. The front-panel power switch also features a recessed design, preventing accidental operation. Plus, with power-off bypass relays, your signal path is preserved when unexpected power failures occur.
