Rockville REQ42-S Silver 19" Rack Mount 2x21 Band Equalizer

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!

That it's a great deal and it works well. I replaced an older high-end eq. This one actually sounds better. You can't go wrong.

Very Poor Quality:- Sound Out-Put (Left / Right) was backwards.- Two control switches on front panel not working.- LED frequency power band readouts act like a kid's toy.This is ok for a cheap kids sound system but, not a real one.

This is the second one I've ordered, for a different room. As an equalizer , this unit does a great job. And yes, if you hook it up properly from your amp in the correct sequence, the light indicators work fine. I'm enjoying the sound enhancement, especially if you have components attached to a standard surround receiver, which usually does a poor job with analog players.However, the shipping department will send the main box containing the unit as is. No other protection. The first one I received was damaged badly because of scant Styrofoam padding inside the box.As someone who occasionally ships vintage refurbished analog units, it is imperative to add a second box to protect as usually there will be damage in shipping. I called Rockwells customer service about this issue. I guess it was ignored. But the unit itself is highly recommended.

Frustrated with the quality of music from several surround systems I have had that were made for movies, I restored my Cerwin Vega AT-10s and purchased a Yamaha receiver to play my tunes. I don't consider myself an audiophile. I just like loud, clean music with plenty of low-end (which is why I restored the Vegas). I purchased an Esinkin Bluetooth audio adapter and the Rockville RQ42-B because I wasn't pleased with the bass response from only the receiver. Not being very knowledgeable of how to get more bass, I took a chance on the Rockville equalizer. I am extremely satisfied.I read all the reviews about the plastic feel of the sliders. They do feel a bit flimsy but I rarely adjust them after my initial set-up. Also, there is not much "play" with each slider since they are so small. The slider lights are bright but not distracting for me. The LED display appears to be purely for show and does not indicate a level of any band.I have my Bluetooth connected to the equalizer and the equalizer to the receiver so I can play music from my phone. It works flawlessly. I can rock out the house cleanly and annoy my wife and neighbors with great stereo sound.If you are on a small budget and want to improve your sound, get the Rockville RQ42.

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...

Gave it five stars, so this will be read by prospective buyers . DO NOT BUY- I went through three types of wires to get my speakers to work Don't buy - save your frustration and time.
