Klark-Teknik DN360 Equalizer

This unit is very clean, and has never toured.  With the exception of some scratches along the top cover, it shows very little wear.  It was removed from the on site controlled storage (IT Room) of a corporate facility.   Date of manufacture appears to be 1995.

You can see from the rear panel photos that this unit has had the Output Transformer option installed and the last photo shows the transformers with the top cover removed.   The inputs are electronically balanced.

FEATURES

• Two x thirty 30mm oil damped precision faders graphically positioned at 1/3 octave ISO frequencies between 25Hz-20kHz
• Proprietary circuit designs utilising "MELT" filters giving unbeatable performance
• Comprehensive standard specifications include electronically balanced inputs and LED overload indicators
• Earth lift switch enables signal and chassis grounds to be isolated eliminating ground-loop problems
• Useful low cut 18dB/octave filters preventing subsonic components from overloading speakers or amplifiers
• Equalisation by-pass allowing easy comparison between direct and equalised signals
• Scale switching gives the choice of either high fader resolution (±6dB) or normal (±12dB)
• Perspex security cover available to order, for use in permanent sound installations where system calibration has taken place
