Rockville REQ42-B 19" Rack Mount Dual 2 X 21-Band Graphic Equalizer Black | 42 Total Bands, RCA Inputs/Record Output, 3.5mm Aux Input, Dual VU Meters, LED Display, Removable Rack Ears

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!

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 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.

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.

A liitle bit of extra noise added to the signal path. Not a high end product. Short throw on the EQ sliders make it hard to adjust. Overall it works well, and happy with it so far.

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 .

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.

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
