The Ashly Audio GQX-3102 is a 2 Channel 31-Band Graphic Equalizer that features a tunable high-pass filter circuit (8Hz to 200Hz), a switch-selectable cut or boost of either 6dB or 15dB. The 45mm full-throw faders are a custom-manufactured metal-shaft type, with the center detented position utilized as an "on/off" switch for that filter which minimizes any possible degradation in signal noise levels.
