I have a CDE-9843 Alpine H/U. i don't really know what it means. for the bass center frequency it has choices of 60Hz,80,100, and 120. the bass band width from 1-4. and for the treble center frequency 7.5kHz,10.0,12.5,15.0.

i am not sure what to do with these settings. what does it all mean? :eyebrow:

thanks

If you have the Base EQ Adjustment at 0, it does nothing. If you have it between +/-1 to +/- 7, this controls the center frequency that is boosted. The Bandwidth controls how wide from the center frequency is boosted. 1 is the widest boost, 4 the narrowest. The Trebel Center Frequency does the exact same thing as the Bass Center Frequency, except for the Treble EQ Adjustment.

It sounds like your headunit has a parametric EQ.

Heres the Alpine page where you can download a .pdf copy of the owners manual-

I'm not sure about the parametric EQ. My 7894 has the same settings and it does not have one.

P-eq. not x-over. the frequencies are for you to choose which you'd like to eq.

so you're saying that what ever the number is at, lets say 7.5 for the treble, this frequency will be boosted more than the others? im still confused :confused: i was messing with one at best buy, and it sounded like the frequency was higher when i turned it to 7.5kHz than it did at 15kHz. im confused :crap:

That's because there's not alot of info above 15k in alot of recordings. At least not the kind of thing you notice easily without some real listening. Boosting 7k would be a much more apparent change.
