I have a Yamaha EMX 501 powered mixer, one of its many wonderful features is the 'High Pass Filter' switch, i am sure it is a common feature on most desks, the manual says stuff, but my underdeveloped brain dont get it, i was a victim of secondry modurn educashun..... it says "The HPF cuts frequencies below 80 HZ"??? whats it for, how do i use it to good effect, can it make any difference to peaking levels?? So many questions so little time...
Can anybody shed any light on this for me??
