Klark Teknik DN360 Dual Channel 30-Band 1/3 Octave Graphic Equalizer with 30mm Faders and Transformer Balanced Outputs, 3U Rack Space

Very occasionally, a design is so correct from the very start that it needs little or no development over many years. The KLARK TEKNIK DN360 has been in continuous production for over twenty years with only one minor design revision and is still the most popular analogue graphic equalizer on the planet. With over 35,000 units shipped worldwide to date, DN360 has achieved ubiquity in pro-audio circles. So why is it so enduringly popular? Like all KT units it is well designed and engineered to very high standards so will handle continuous road use with only minimal service.

They are also very consistent, so engineers using units sourced locally all over the world will get the same response every time. But perhaps most important of all is the way they sound - it's notoriously difficult to describe sound, but talk to anyone that prefers DN360s to any other graphic and they will use words like 'musical' 'smooth' 'responsive' and 'great sounding'. Primarily this is because they use proportional-Q filtering, where the 'Q' value of the frequency increases as the cut or boost increases. This provides a flowing response at low cut / boost values, but also accurate frequency control at higher values.

• Classic Proportional-Q equalization for optimum control of frequency response
• 18 dB/octave low-cut filter per channel to eliminate unwanted subsonic frequencies
• 30 mm oil-damped precision faders with center detent
• Channel bypass and graphic EQ scale selection switches
• Power-off bypass relays
• NEUTRIK XLR Connectors configured pin 3 hot
• Rugged 3U rackmount chassis for durability in portable applications
• Designed and engineered in England

DN360 Architect's and Engineer's Specification
The equalizer shall provide 12dB of attenuation and accentuation at 2x30 1/3 octave ISO center frequencies from 25Hz-20kHz. Each equalizer shall allow for; subsonic frequency attenuation at 18dB/octave, equalization section by-pass and shall be failsafe, that is the unit shall return automatically to the by-pass condition in the event of power supply interruption. Each equalizer shall use center detented slide potentiometers arranged to give a graphical display of frequency plotted against level.

A rear panel switch shall be provided to isolate the signal ground connections, quickly and safely, from the chassis ground. All audio connections shall be via XLR style connectors and a tamperproof front panel cover shall be available to fit the unit. The unit shall be capable of operating from a 115/230V +/- 12% 50/60Hz AC power source. The equalizer shall be the KLARK TEKNIK Dual Channel Model DN360 and no alternative specification option is available.
