|   INFO ON FREQUENCY AND EQUALIZER ADJUSTMENT | AldoDean
May 18, 2001 10:49 AM | | Does anyone have any information on setting up and tweaking an equalizer? I don't have and can't find any explanation of frequency modulation on the web. It's frustrating, because I think I can get my system to sound better, especially for DVDs. Are there any sites or links you know of? Thanks a bunch.

Specifically what kind of information regarding eq's do you need to know. I will be glad to provide whatever knowledge I have to help. I ask this because your question is a bit convoluted. Eq's can't be tweaked. You use eq's TO tweak.
As many can tell you, I am not an advocate of cheap equalizers. A simple octave band eq will do you no good in most rooms. Especially smaller rooms were modes and nodes are a real problem. Sonically, they can make your system sound so bad, that it is better without them. If you do purchase one ocatave eq, Audiocontrol should be the only model you look at. Another reason not to get one octave eq, involves how much each slider will effect adjacient frequency bands. If you adjust the 63hz slider, it effects will be heard almost another octave up. This is not good, since you may not have problems in the other frequencies. However because of this adjustment, you may have problems now.
One ocatave band eq's just do not have enough resolution(frequency band controls) to really help a HT system. For most rooms, 1/3 octave band eq's are much better, though 1/10 and 1/20 is better than that.
It takes knowledge of acoustics, and speaker interaction with rooms to effectively use eq. This is one area where the knowledgeable can get fantastic results, and the uneducated, disasterous results. This is the reason that Eq is not recommended by most people. It is better to know what acoustical problems you have before you deal with eq. Or, you will just make a mess of good audio.
