[QUOTE="cacin, post: 2484858, member: 10222"] What oldskol mentions already sums up most of the confusion between the pre-amp thing. The note that I want to highlight is, some graphic EQ are also designed to look like a parametric eq. The cap ayam one with knobs. Those can be said as graphic too right? I think a parametric EQ must have the ability to adjust the bandwidth (Q factor). One other thing, If you have multiple slope crossover working, you will have a different slope in the end. IE: Hu LP at xxHz at -6dB, E-X-over LP at yyHz at -18db and amp LP at zzHz at -12dB. There is a formula to calculate the slope (but I forgot). The question of what is the actual LP frequency in the end - I have no idea. Need to check back my book. [/QUOTE]
