dbx 231s Dual 31-Band Graphic Equalizer
dbx 231s Dual 31-Band Graphic Equalizer is rated 2.3333 out of 5 by 3.
Rated 1 out of 5 by from DBX 231sI bought one of these from another company. Sent it back because it was too noisy, and bought another more expensive DBX Dual 31 band EQ.

Rated 4 out of 5 by from Does the jobDecent and clean enough for my uses. Helps me balance the hodgepodge of equipment I have gathered over the years and get a good overall result. Also road worthy and wallet friendly.

Rated 2 out of 5 by from Don't really like it..........Biggest problem I see which I didn't notice before I bought it is the 50hz 12db filter? Why in the world would a company want to filter a full octave (and more) of low bass out when most speakers roll off the low bass anyway. A 20hz filter is what's needed. It also clearly sounds better through the XLR interfaces vs the TRS outputs which seem to not generate enough output and has a slight hiss.I'm going to keep it but had I known I would have looked for a better unit. Filtering low bass below 50hz out is the most ridiculous thing I've ever heard off for an audio company to do.
