BehringerULTRAGRAPH PRO FBQ3102 Audiophile 31-Band Stereo Graphic Equalizer with FBQ Feedback Detection System

I waited until I had put this through it's paces to give a review.This is definitely a professional-grade EQ - you are not going to plug it into the stereo you bought at the local Target without some serious research into converting pro connectors to consumer connectors. With that said, when fed from the right quality of source and with a good amp after it, you can fine-tune to account for any environment.Pros:Rack-mountXLR and TRS connectionsClear indicators for at-a-glance referencediscrete subwoofer output with adjustable cutoutCons:Inside heat sink should have been vented to outside air - it gets very hot in some configurationsThis is worth it if you have the setup to match it's capabilities; if all you have is RCA jacks, plan on some work to get it going, and do not skimp on the cables.

My old MXR finally died after 30 + years of use. After doing everything I could think of, and replacing this and that, it was a forgone conclusion it had done all it had come here to do. Bummer. Saw this Behringer EQ and picked it up. Had to use XLR at first then used the 1/4" phone plug cables which work just fine. Power up and ops are fine but there is some very quiet ground loop noise on Ch 1. Still working on that one but thinking is a good ground system will fix it. Because it is so quiet and a fairly low noise floor, I won't lose sleep over it. It only went in the old stereo system and the price certainly is right. After some tweaking and tuning, the EQ seems to work fine with very good response. Levels are happy around the neutral gain setting. Everything else sounds fine and you can really get some nice effects. The nice thing about having 31 bands is being able to do so much more. If you get it, start with small changes then work your way up. You'll find some nice response after a while and some patience. I had to pull the rack mount ears off so it would fit in the audio cabinet but it does and that's a big factor. If using in a similar cabinet, be sure to measure. This is not a high dollar piece of equipment and using in a high end environment may or may not work for you. If you are on a budget and need good sound, I can't see where you'd go wrong.Disclaimer: Remember this, as with most audio, is very subjective and everyone will have different tastes, likes and dislikes.

This EQ really sounds great. Really woke up the sound on my Cerwin Vega XLS 215’s. Powered by a QSC 2500 watt amp. Professional audio set up.

I love this equalizer. The feature of the little lights on the faders that respond to the signal on that frequency makes setting them (Ringing them out) a breeze for a live sound situation. I crank up the volume and when feedback starts to occur I can identify the guilty frequency very quickly and bring it down until it goes away.then crank it more, and repeat It gets the job done well and really quickly. When used for monitors, during the process of setting the equalizer it can be helpful to lower the output on the power amp. That makes the signal going through the equalizer stronger and the lights easier to see. When done bring it back up to provide headroom.

This equalizer works fine and is easy to use. But I am uncomfortable with the high heat it generates. It gets VERY hot on the back panel around the sub output. It gets so hot in that area, it hurts to keep a finger there. This is very strange as the heat is generated even when the EQ it not wired to anything but the A/C power. It is not on top of warm equipment either. I have observed this high-heat behavior on two units. Two different calls to Behringer yielded two results. The first time it was suggested that I exchange the device, which I did. The second time I was told the heat was O.K. Weee, multiple choice from customer support.

Excelente calidad

An equalizer for the price, easy to manage and ajust. Really good with my 2 Cerwin Vega XLS-215 when i'm home in my 20m^2 room made of plaster i can turn up the low frequencies to get a bit more feel to the sound and when i'm out in big concrete rooms i can turn it down and ring it out to get the perfect room fill of low, mid and high frequencies.
