Rockville REQ42-B Dual 21-Band Graphic Equalizer, 19" Rack Mount, RCA In/Out, 3.5mm MP3 Input, LED Indicators, VU Meters, for Studio and Live Sound

Of course, this is not the best of the home equalizer I have owned. This is the cheapest of them as I paid a lot more for the other ones. Simply, it does its job and I like it. Too many bands to adjust compare to my old ones (I still have one of them in use), therefore it is just a matter of practice to get used to that many controls to adjust. The spectrum analyzer is just an indicator of the input level not by frequencies but the overall sound, that is why it moves all the bars the same way always but it really responds to the overall sound input level. Another thing, most of the superior equalizers for sale, are more suitable for PA systems not necessarily for your home system but this one is. Even some people criticized the instruction manual, I don't need any kind of instructions to set up an equalizer to my home system, it is so basic. Recommended product for those who don't want to spend a lot of money and have some kind of experience in setting home stereo equipment instinctively, no instructions.

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!

Buck up and pay wayyyyyyyyyyyyyy more for a REAL equalizer cause this is a cheap inferior product.....the flaws before it started buzzing 2yrs ago aside.....DON'T BUY IF YOU ARE A TRUE AUDIOPHILE

Good quality product. There are a few things to improve Aesthetics: size and material of the brand name; instead of serigraphy an engraven in metal finish would be more appealing. The fluorescent graphics section should off when there's no signal. Leds on the bands controls should be dimmable. Sound quality is excellent.

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...

I was a little disappointed in reading reviews and finding out there was no spectrum analyzer, but no biggie, my main reason for getting this was to be able to adjust the sound profile more discretely, and this Rockville unit allows me to do just that. I have this hooked up to an old Yamaha AV receiver (before HDMI was a thing) and I have an old Kenwood dual tape deck, a turn table, and a 5-CD Harmon Kardon CD carousel. The tape deck is a new addition rescued from neighbor's trash so I was just glad it played. It sounded OK but a little muddy. Passing it through the EQ made it much crisper and brighter. My wife remarked that she was hearing things in the music that she hadn't noticed before. CD playback was better than it's ever been out of this receiver and speakers. Turntable is having an issue but that's not anything to do with the EQ. And FedEx delivered this a full week earlier than expected! If you're looking to set up an old-school 80's/90's component system, this EQ is a great addition. And the "spectrum analyzer" is pretty.

Not a bad product ...actually it is very usefull : I match it with my vintage Pioneer tube SX-34 to compensate for the speaker low range side. Pros - the 21 band equalizer is pretty linear. Don't really care about the graphics since that is more of just a signal indicator. The slider pots are simple . For proper usage , use direct first to understand the baseline sound and then start with flat settings on the equalizer. There from there do some fine adjustments if needed. Cons - that blue LED is sometimes annoying at night , but not sometimes it is good too to know if adjustments is correct. I wish they add an override control on those. The graphic equalizer display is just for level indicator not really a spectrum analyzer . Still this is a pretty good equalizer .

Chegou muito bem embalado dos EUA. Ótima qualidade e equalização eficiente. Analisador de espectro só mede o volume de áudio, não por faixa de equalização. Bonito equipamento.

be careful when ordering to a country where 240v is valid, because this device is 110v, it exposed me to an unplanned purchase of a 240v to 110v converter. Of course, the description does not say anywhere what voltage the device is designed for. Regards

Works well with my stereo
