properly setting LPF

[fmedina]

nice! that really helpful now i know how to set my lfp wooop lol

if you use a DMM, the voltage will drop above your LPF setting. If you play a 68hz tone and get your max voltage reading(ie. 34volts) then at 69hz it reads less (like 31volts), you know that is where your LPF is set at.

EDIT: sorry I didn't really read what he wrote.

What he is saying is to set your amp to the desired voltage output, play a test tone where you want your LPF to be set at. Turn your filter adjustment down until the voltage starts to go down and then you know where your LPF is set.

Is this the same for setting a hpf?

Yes the same for hpf and ssf. I believe with lpf setting u want to turn the knob up until voltage drops. If you want it set at 80 Hz, play a 80 Hz tone. Start with the knob at say 60ish and turn it up slowly until the voltage begins to drop. Tahdah.

Hpf you go the other way. Play a 125 Hz tone and start with the knob higher than that and turn it down until volts drop.

Ssf its safer to have the subs unhooked. And follow steps for settings lpf.

Well, I did that and the voltage started to drop immediatly. Are you looking for a quick drop in voltage when turning the knob ( slowly of course ). I ran a 80hz tone with the HPF set as high as it could go ( 1k ) and was still hearing the tone through the speakers.
