What a great buy. The Rockville Equalizer makes the music really sound great. Excellent quality. Easy to operate. I just wish the hook up instructions were better. After playing with it for a while I finally figured out how to hook it up to work with a vintage receiver. Was able to hook up a Bluetooth receiver to the Aux input to play through Bluetooth from my phone. Everything works good. Great light show. What is not to like? I highly recommend.

I normally don't write reviews but this time it's different. This EQ has brought me back to the 80's. The sound that comes out of this box is mesmerizing! I can't stop listening and watching it hooked up to my Yamaha Stereo. If your looking for one of these, trust me....this is it! I'm going to order another for my garage system. This is not a 5 Star review.......its a 10 !!!!

Excellent price spot for this type of equipment. I've seen similar and even less effective equalizers sell for double or even triple the price. Excellent value!

Good value for price
First of all, your expectations have to be in line with the price. The slider controls for each frequency band are a bit fiddly. The spectrum analyzer is nothing more than a static image of bars that move with the sound signal in the fashion of a combined channel VU meter (not true spectrum analyzer). I purchased it for the ability to record to a cassette deck by utilizing the secondary equalizer output on the back of this unit. I have this secondary output connected to a passive preamplifier (glorified signal switch) and I have two cassette decks and a secondary CD player connected to the passive preamplifier. This unit is very light, but all the fit and finish are clean and as designed. My unit remembers what the last source you selected before powering it down (if you select ...

My unit remembers what the last source you selected before powering it down (if you select tape, power down the unit, it will be on tape at start up again). Overall, for the price, I think this is a good value. You can purchased a used equalizer, but you will have to deal with the 30+ years of deterioration. Maybe worth the risk???? Maybe not.

What you see is NOT what you get!
First and foremost what follows are the actual dimensions: Width: 16 9/10", Depth: 9 1/16", Height: 3 9/16" maximum. 19" is a total untruth. Much of the rest of the machine is a bunch of BS as well: the "spectrum analyzer" is little more than a light show displaying no useful audio information; 21 sliders per channel, where-as certainly looking impressive in fact provides no perceivably better sonic control than a 10 slider per channel unit, it just makes for more work; buttons must be reset each time you turn the unit on; too bright - no way to dim the LEDs on the sliders; 3 prong plug makes integrating into system more difficult - a 79 cent adapter works OK for me. I could go on with faults but I won't because it's essentially a cheap product and you get what you pay for. But as a ...

I could go on with faults but I won't because it's essentially a cheap product and you get what you pay for. But as a graphic equalizer it does exactly what it's supposed to do. I have my Rockville set up in my bedroom system where it makes my small Polk Audio bookshelf speakers sound like large Polk Audio bookshelf speakers and oh so fine. Be careful, and subtle with your sliders and with this machine you can do the same.

Good, but only for limited applications
Small sliders are nearly impossible to set accurately. Bar graph is not a real Audio level meter for each band and jumps around In regular lighting the blue LEDs are glaringly bright right channel is slightly louder than left. Audio was clear. easy to install

Great equalizer for low budget systems
Amazing sound upgrade with 21 levels of adjustment for your liking for what you want to hear coming from your speakers. Can't beat the price either. I purchased another brand for my lil system at work that is the same one just a different name for about $50 more. Wish I would have seen this one first to save that $50. This eq will not disappoint you.

Functions great...but
It's a 21 band equalizer, it does that. Gave it three stars because 1. the spectrum analyzer looks more for show than anything else 2. There is no way to stop the spectrum analyzer from continually cycling through it's display modes 3. As every one else says, the blue leds on the slider controls are WAY, WAY too bright
