graphics vs parametric EQ

[HNaga 10+ year member]

In my Alpine CDA-9887 there is graphics and parametric eq, what is the difference and what to use and why?

When you're making EQ adjustments, there are 3 parameters to be aware of - amplitude (how much you're boosting/cutting the frequency), the center frequency, and bandwidth (how far above/below the center you're adjusting). A graphic EQ has the center frequencies and bandwidths fixed. A parametric EQ allows you to adjust all three, although the number of center frequencies you can choose may be less.

Both have their uses...although setting large graphic EQs with lots of resolution pretty much requires use of an RTA.

I know I've covered this topic atleast a dozen times, in detail.

So parametric has extra setting for center frequencies and bandwidths.

I need example by value.

Read your manual Naga, I have the 9887 as well and this is detailed in the manual.

I personally use parametric. I feel it gives you more options. You select the center frequency, Q factor, and whether you want to amplify it or decrease it. Graphic you can only choose whether to amplify/decrease, the frequency range is predetermined.

Graphic has 7 bands though, Parametric you can only select 5. But I feel you get better tunability with the parametric.

I did, but the mnual mentioned how to use , not the difference or when to use what.

Use whichever one looks the prettiest to you. Because, in all reality with the way that Alpine sets up their EQ in parametric and in graphic there isn't much difference.

I have switched back and forth before and never really noticed much of a difference overall after tuning everything in.

Just don't crank up and down things unnecessarily. You are actually better off to take out the hot frequencies and to boost the weak ones.
