Baxandall-style stereo equalizer with Bass and Treble Boost and CutBaxandall-style stereo equalizer with M/S processing, equal-channel equalization, and Bass and Treble Boost and CutThe shelf curves are named for their asymptotic Boost and Cut range, where the magnitude of the Boost and Cut increases until it reaches an asymptotic valueAsymptotic: a term of Greek origin referring to a curve that extends indefinitely toward a straight line without ever touching it.The Boost and Cut curves get “dangerously” close but never coincide, providing ultra-high treble and very deep bass that always remain under control.Tuned, sweet, and natural sound.Parallel equalization that exceptionally reduces phase deviation and the rare artifacts so common when “twisting” equalization curves.Treble:Frequencies: 24000, 20000, 15000, 12000, 10000 and 8000Hz10 dB Cut and Boost with 1dB or 0.5dB gain stepsBass:Frequencies: 470, 360, 220, 110, 60 and 20Hz10 dB Cut and Boost with 1dB or 0.5dB gain stepsHigh-pass filter at 160, 82, 47, 22, 15Hz and OFFLow-pass filter at 10000, 12000, 18000, 22000, 30000Hz and OFFSwitches:ON / OFFM/S processingL BypassR Bypass2 inputs and 2 outputs via XLRCarnhill Oxford input transformers and Carnhill St Ives output transformers.External power supply
