EMB Professional Sound System EB631EQ Graphic Equalizer

Once the 115V transformer was changed for one working from 240V it is fine. However, a straight 240V: 12V: 12V does not work and required some extra turns to be hand wound to achieve the open circuit voltage of 18V: 18V. A straight 240V: 18V: 18V winding gives too high an open circuit voltage. Once this bifilar winding of about 46 turns was added to the 12V: 12V to make 18V: 18V open circuit everything works well. The unit provides excellent performance at a good price. The morale is to make sure you have a unit for a working voltage of 240V. The units are available with alternative input voltages.

Best deal out there on equalizers, works great, sounds great, if you own a 10 band EQ ditch it and get this you won't be sorry. Only one thing I wish they put the on-off button on the front not the back, but as the owners manual states, when not in use it uses such a small amount of power that it can be left on at all times.

Cheaply built, has no power button on front but with adapters and a tape loop you can connect it to a home theater receiver. (Old ones)

Highly recommend good quality

do not buy this unit? This equalizer looks great, and it sounds pretty decent. But if you love music as much as I do? I could hear a small hissing noise in the background. I don't know if, if I'm the only one that got a bad product. there were a lot of good reviews on this equalizer and just a couple bad ones. I bought this unit for my receiver (Pyle P3001AT 3000W Hybrid Pre Amplifier with AM/FM Tuner) that I got off from Amazon. This unit is one of the most junky receivers I have are came cross. I received this receiver about a month ago. January 5, 2016. And it already blew the left side of this receiver. There were a lot, I mean a lot of bad reviews on this receiver.( but did I listen--NO!! ) this receiver cost me $143. And I can see what the people are talking about on this receiver. I got this EMB Professional Sound System EB631 equalizer,for my Pyle P3001AT 3000W Hybrid Pre Amplifier with AM/FM Tuner..( and both of them were junk!! ) don't be like me? And buy this thing. Is not worth the money and the time you will put into it. A wish I listen to the reviews. If you get money to burn? This unit is for you.

Perfect for church / easy to use / sounds great / fixed our feedback issues!

Very impressed with this eq.. sound quality is great.. only thing I didn't like about it is that it doesn't have a power led to know if it's on or off.

It's ok. Lacks Pzazz.

Lo eh usado poco pero funciona perfecto se ve de construcción solida de buena calidad.
