Equalizers (EQ)
ThePC3KhasbothGraphicandParametricEQalgorithms.ParametricEQsectionsarealso
foundonanumberofcombinationalgorithms.
TheGraphicequalizerisavailableasstereo(linkedparametersforleftandright)ordualmono
(independentcontrolsforleftandright).Ithas10bandpassfiltersperchannel,each
ofwhose
gainisadjustablefrom‐12dBto+24dB.
