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

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.

Fantastic unit. I wish it came with a true user's manual instead of just a link to YouTube videos, but I love this unit.

July 2023 // This EQ sounds great in my system. The only thing I see that I don't care for is the operation of the cheesy Level meter. It looks like a Spectrum Analyzer but only bounces up and down based on the input level and band settings. I would prefer a regular VU meter...LED or analog... the way this meter works cheapens the look of the unit to those of us that can grasp what it is actually doing. Despite what I see as a single flaw, It is a great little unit for the price. // Now November 26, 2023... After only 4 months the first of the level markers on the sliders has failed. I guess poor construction practices are a sign of the time.... Now 10 months later...on my second unit an on this one, way worse, all the spider lights are on and off all the time. Still sounds great, but lets be real....need to look like quality as well. Nov 30,2024- the left channel went static and failed. Not going to try a forth unit. Think I'll just trash this POS and look for one that offers at least for quality. DON'T BUY THIS!!!!!!!!!

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 .

This is not a normal EQ setup. It has no line in line out tape playback/ tape record. Instead yo hook your components straight into the EQ. The there are 2 sets of outputs. I have one going to my amp and the other to a cassette player on a old analog system. I also added a bluetooth reciever to it and it works great. The problem with this is the dumbest stupidly engineered fake spectrum analyzer! What in the hell were they thinking? It pretty much does whatever it wants? Changes colors changes position from normal bottom up to top down? Dumbest thing Ive ever seen! And no way to change or control it? Other than that BS it works fine and sounds ok for what Im using it for. Adjusts the sound just fine. And only 70 dollars. Im good with it.

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.

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
