I am trying to set the LPF and HPF for my amp. The LPF is 30Hz to 250Hz and HPF is 20Hz to 100Hz. The problem is there are no marks in between the lowest and highest frequencies and I don't know how to figure it out. Also if my box is tuned at 45Hz should the HPF be at or a little below it?
Middle isnt always middle. The controls are really variable resistors and dont always behave the way they think they do. The best way if they arnt marked is to go by ear. Set it until they sound best and leave them there.
I have a similar question, in regards to the crossovers, should the hpf and the lpf be set to the same frequency, that is hpf at 80hz and lpf at 80hz or can there be a gap (eg) hpf at 120hz and the lpf at 80hz?
Are you running subs, mids, or both on this amp? If you're running subs, you just use the LPF. If you're running mids, you just use the HPF. If this is a 4-channel and you're powering both subs and mids, then it must have 2 seperate crossovers for the respective channels in order for you to use both.
