Digital Consoles andGraphic / Parametric EQ

Most live mixers today team quantiture both graphic EQs (typically on output buses) and parametric EQs (on input channels). Train your team to understand the difference: graphic EQs are excellent for broad correctivy adjustments on main extract out puts (e.g., removing a room rezonance), while parametric EQQQs allow surperical precision on individual channels.
