Don't Buy It - Noise Problem in Channel Two

By Synnic

from Olympia, WA

See all my reviews

Comments about dbx 231 Dual 31-Band Graphic EQ:

I give this EQ 1 star because although it would otherwise be a good unit, it injects a completely unacceptable level of noise. Want to see the problem? Hook up a dbx 231 and set the sliders for 3.15k and 6.3k on channel 2 all the way down. You get a terrible hiss. Note that this is a design flaw and not an issue with just one unit, and that it does this with other bands also. It's just most audible with 3.15k and 6.3k. I've had 2 of these now and both do it. I will not buy another and I cannot in good conscience sell it to someone else without disclosing this. I've also had the salesperson at my local music store confirm that the problem exists in other 231 units there.

Comments about dbx 231 Dual 31-Band Graphic EQ:

We use 2 of these on our PA system. One is set and locked up, the other is for the tweaking the sound of the bands, and all I can say is wow. It's dead quiet in the signal loop and has execelt quality in the mix. The only downfall is that it's hard to tweak the settings in the dark. But we have it right under rack lights. But overall, very good product.

Solid, Simple EQ

By Levy

from Minneapolis MN

See all my reviews

Comments about dbx 231 Dual 31-Band Graphic EQ:

I use 3 of these for my 6 monitor feeds. They are easy to use, have near silent operation, and I have never had a problem with reliability. Some people on this site have commented that they are difficult to operate in the dark, which I think is a silly comment. Use lights. This is not an ultra high end EQ with many features, but it never claims to be. This is a simple no frills EQ that I would recommend for both its low price and high quality.

Excellent product!

By GLSman

from Portland, Oregon

Comments about dbx 231 Dual 31-Band Graphic EQ:

There was a problem with the level LED circuit creating a high-frequency oscillation in the output of each channel. It didn't interfere with use, it was only a few millivolts, but they paid to return it and fix it. Now it works perfectly, and I am very pleased with the quality and value.

Comments about dbx 231 Dual 31-Band Graphic EQ:

For the price it seems okay, but haven't fully got into figuring out how to use it. I does have an annoying problem a little him in the system. I have checked all the cables and they are not the source.... disappointing, I hope to filter it out
