[QUOTE="Riley Casey, post: 132236, member: 125"] Re: newbie question about HPF on mains No. High pass filters are your friends. Use them liberally. There are limited ways to implement high pass filters economically and a second order Butterworth is pretty widespread. A second order Butterworth on say a vocal mic on the input strip of the console in series with an assortment of third octave filters on the mix graphic in series with a second order high pass on the graphic EQ main output is going to have far less detrimental impact than the entire mix to the woofer modulated by out of band low frequencies or worse yet that 15 hz thud when the bass player pulls the plug from his instrument with the DI output hot to the PA system with a lot of 40 hz boosted on the channel EQ.
