Rockville REQ42-B Black 19" Rack Mount 2 x 21 Band Graphic Equalizer EQ

I bought a pair of bookshelf speakers to use with my computer, and the bass and treble control didn't give me any range, (the base all the way up or down sounded the same). This was easy to hook up and does the job probably too well, meaning that 21 bands is a little overwhelming, but in my case I only had to set it up once. I'm happy with this purchase, the only downside to me is it has to be on to get any sound, (the display not the equalizer, the equalizer can be turned off or on), however my speakers have two sets of speaker jacks, so I hooked up line one to the computer and line two to the equalizer, hope this helps.

Excellent Sound Quality, Love the tailored sound!! Weakness would be the slides are delicate

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!!!!!!!!!

Good unit, but in my system the pre-amp will ad distortion to the signal. I did get it dialed in to an acceptable sound. Was delivered in the box only, with no external packaging.

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.

Truly a great product.

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...

Great quality not bad. Would buy again

Fake listed

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

Excellent
