Alpine 3401 Equalizer.. Need help.
My buddy gave me an alpine EQ to lpay with,
it's a 4+3!
So it runs in 7 band mode
as in
band 1 20-700
band 2 150-5000
band 3 1.2k-22k
band 4 20-700
band 5 70-2.6k
band 6 400-13.2k
band 7 1.2k-22k
Also it has slector switches:
OUT EQ IN
[___[||]__]
I'm not sure what to do with it
and i cant find -anything- on this EQ on the net. i think it's from the 80's.
I just want to play with it to see if my systme could benefit from an eq..
anyone ever had this unit or experience with it?

Re: Alpine 3401 Equalizer.. Need help. (Kale)
I meant I don't know the specific EQ. Most times, but not all, they really don't add much to a system and often they take away from it. One more way to introduce more distortion or engine whine. My shop was pretty biased against them in most situations. They are supposed to be used on systems to help flatten out peaks and valleys on a flat sound curve. The best way to tweek it would be to get a white noise generator and a tester and check to see what you need to flatten it out. If you have any buddies at a shop, they probably will have one.
Most EQs are junk for kids to push up the bass and treble in the classic V pattern which essentially mimics a loudness button anyway. Alpine though had some decent stuff. Good luck with it.

Kale,
what do you want to know? I own several of these. Great eq.
The selelctor switch will let you run it three ways:
1 input(l+r), 1 output, with seven bands of eq for that input
1 input, 2 output(f+r), with 4 bands on the front, 3 bands on the rear
2 inputs, with 3 bands on one input and 4 bands on the other input.
The in/out switchs just let you bypass the eq circuitry and pass the signal straight through without being affected.
to be honest, to get the most out of a parametric, you need access to a spectrum analyzer to make your adjustments. Parametric eq is far more powerfull than graphic, just more difficult to adjust.
Let me know if you have more questions.

hmn, i've been trying to do it by ear. I've managed to tweak the tweeter a little, and reduce some of the resonance ~120hz. But all the other settings make it sound worse... Must be normal.
