The equaliser shall provide 12dB* of attenuation and accentuation at 2x30 1/3 octave ISO centre frequencies from 25Hz-20kHz. *Selectable to 6dB for increased fader resolution.

Each equaliser shall meet or exceed the following performance specifications:

Distortion (THD+N) < 0.01% @ 1 kHz,+4 dBu
Frequency response (0.5dB (20Hz-20kHz)
Noise <-90dBu (20Hz-20kHz unweighted)
Maximum level into 600Ohm +22dBu

Each equaliser shall allow for; subsonic frequency attenuation at 18dB/octave, equalisation 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 equaliser shall use centre 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 equaliser shall be the Klark Teknik Dual Channel Model DN360, and no alternative specification option is available.
