I think many ppl get confused. You still need a bass knob regardless for bass. It's what I usually use for hip hop. Epicenter is used and turned up when im listening to corridos or banda to desried volume. Now depending on music you listen to the bass knob controls sub (power) level and epicenter processor expands whatever freq you set it to. It does not add bass it simply restores missing bass. For ex: Idk if you ever had an issue where you turn up the bass with certain music and it just doesn't even sound good or bass not well composed? That's where this device comes in. That's cause your turning bass to high and trying to play sound that isnt there you'' get a lot of sloppy notes making you think its your set up. Ill turn up bass knob a bit then epicenter according to type of song Im playing. Im no expert but hope this helps guys.
