Rockville REQ42-S Dual 21-Band Graphic Equalizer, Blue LED Sliders, RCA Inputs, Rack Mountable, for Home Theater and DJ Audio

Thank you !!

I highly recommend the product, the price is very, very good and the quality is great, I'm delighted with my equalizer, I highly recommend it

It has a display of bands that are supposed to represent what's actually happening with the music. However, there's the same pattern of display for any music. It doesn't change. Oh, it does go up and down but it's only based on level. Not frequency. Don't do it.! It's fake. Rockville should be ashamed of themselves. Any basic electronics knowledge is all it takes to understand that this is doing very little. I would say that functionality is minimal. Kids might enjoy this. The brightness is OK. Nice pretty colors if you like blue and blue.

The media could not be loaded. After I bought this I read some of the reviews and I was like well save all the packaging cause we’ll probably be sending it back. Well I don’t know what everyone is complaining about. It works as an equalizer and does just what I wanted it to do. I subtracted one star because the led level lights do not actually follow the frequency levels. It’s more show than go. But the bottom line is……..IT WAS $58!!!! What the hell do you want?????

My prior EQ has been on onr stereo unit of mine or another for 40 years! A few years ago, it started giving me problems and I bought another EQ which really let me down to the point where even though the old one was flaky, I connected it back to my stereo. But it was time to say goodbye. I purchased this one and got it the other day. I like having all the bands to shape the sound as you desire and also the fact that you can control each speaker separately with two separate bound waves. The blue lights are cool looking but I would admit that would be nice to be able to dim them or shut them off, as they are staring back at me and are very, very bright! But it sounds good. I didn't think an EQ made that much difference on the sound as far as the unit itself, but after buying the other one that I pulled back out of the system, I found out that it does! I've only had it a couple days - but so far, so good. Hopefully, I will get many years of use out of it. I would love to purchase a fully remote control unit one day if they have them. But other than that, it seems like a really good unit at a very fair price!

Nice and inexpensive equalizer with bright blue LEDs which match my setup so I was happy… The meter is a bit strange. Looks like a Frequency Analyzer but it isnt… the slightly more expensive version has an analyzer which I would have purchased had I known it existed but considering how badly its advertised on this site its a wonder I found it at all… So … Its nice eye candy and has some EQ uses but would have been so much more effective with a remote for all the separate inputs the unit has, though I did find a way to route it through the line in/out on my modern Yamaha Receiver so I can use it to modify all aspects of the sound in my system… You get a lot for the small cost, but I would have paid more if, again, it had a remote like all my other components do…

Having an all-silver component setup, it was nice to find something in a matching color with lots of pretty lights on it to add to my system. However, that's about all this EQ is - pretty lights. The sound quality overall isn't bad, but when the EQ is enabled, there is a high pitched background noise coming through the speakers. I know it's not an issue with any other component in my system because it doesn't come through when the EQ is disabled (set to 'direct' on the system) and wasn't present before I added this unit into the mix. I tried different inputs, changing out cables, setting all of the sliders to 0, etc. but it's definitely an issue with the wiring/grounding in the EQ portion of the unit itself. It's not noticeable when a loud song is playing but is intolerable during quiet portions or when nothing is playing.As other have said, the LED's on the sliders vary in brightness (and the brightest ones are very bright) so that's a drawback on an otherwise quality appearance. Many of them also crackle when being adjusted - nothing some pot cleaner wouldn't fix - but brand new out of the box there shouldn't be any oxidation on the contacts so that's another issue for my unit. I was also disappointed that the spectrum analyzer is only four bars on the right side of the display (nothing is displayed on the left side, seems a waste of space) and there is no customization - it cycles through different display modes on its own accord but doesn't allow you to select one of your choosing. In the user manual, it says it features dual VU meters. If there is a way to display a second one on the left side, it doesn't say how in the manual and all of my fidgeting with the buttons didn't make it happen either.Overall, it's not a bad product for the money, but it isn't without it's problems and a high-pitched background noise is not worth the improved sound otherwise. It may just be my unit with a loose connection inside somewhere but I'm not going to open it up to try and fix it. I'll give it a few more days to see if it's the type of issue to subside over time but I suspect I'll be returning it and shelling out a bit more for an Akai EA-A7 I was eying up before I pulled the trigger on this...
