Dual 21 Band Professional Stereo Equalizer with Individual LED indicators

The Led Lights Are So Bright You Almost Need Sunglasses To Look At It. They Should Have A Switch On It To Dim Or Shut Off Like My Last Pro Tech EQ Did. The Sound Is Awesome Better Than My Last One With Less Bands On It. I Have Bought Lesser Quality EQ's In The Past This Is Probably The Best One Yet!!!

Like the size and sturdiness of the product. Sound quality was fine, expecially for the price point.Didn't like the slider db controls! only one inch tavel to swing form -12db to +12db makes it almost impossible to place the slider with any hope of accuracy. and the numers on the scale are so small. BUT to top it all off you can't even see the whole slider control panel when the egualizer is powered on because the overly biased blue LEDs are so bright that yoo can't even see the palen markings to make adjusrment, The final gtcha is there is no detent at te 0 db point so it's impossible to get all 21 slides linned up at zero. U used an 8 inch book edge to get them all even bot really couldn't tell if they were right on 0db. Another irratant is the two channel slide sets are stacked vertically and they aren't lables left or right (or channel 1 or2 to match the rear connector labels)As an engineer, my guess this whole mess was a project for a summer intership for an engineering student. But it sould have never been released for production.Pardon my French bit this product is pure Garbaaaajjjjj...I returened it to Amazon after an afternoon of fustration trying to use it!

I just installed it and made a big difference in the sound quality. Not the best but good for what I paid for. The only down side is that the LEDs are too bright and blinding.

I like what it supposed to do and it works great.No Complaints 👍🏼

In what seems like my never ending saga to replace a decades old equalizer this was my second attempt, after a failure with a Pyle Pro PPEQ100. I was excited by the prospects of the EQ7153, after all, a 21 band equalizer seemed like the perfect addition to my system, however, the search remains far from over, here's why.Out of the box the Technical Pro was interesting, it features a shallow design, less than six inches deep, not a problem, just unusual and in a way I applaud them for not filling a box with air. I also was immediately impressed with the material's, the face plate had a brushed metal appearance, somewhere between black and midnight blue, very attractive and the logo was small and discreet. The sliders felt good and overall the unit seemed well put together. I'm only going to mention this because I commented on it with the Pyle Pro, here again is a grounded plug, fine, but its still a hassle for those of us hoping to plug this into the back of a receiver. I guess I have to let this go with the caveat that the cord is very short and is a pain if there's much more than 3 feet between the equalizer and the nearest outlet or power strip.Once connected I powered it up, and right away out came the sunglasses! Technical Pro must be using the same supplier as Pyle Pro for these LEDs, wow! Intense, made even more so since there are 42 of them! Even from across the room these are bright, distractingly so. Again, the only people who are likely to appreciate this are DJs working in the dark, if you are at home you'll be annoyed, trust me. Let's tone down the light show and let the sound quality be the defining feature instead.Moving on, let's start to see how it worked as an equalizer. With all the sliders set to neutral the first thing I noticed, aside from my retinas burning, was the low hiss of distortion from my speakers. Not good. I switched from the equalizer to direct and the distortion disappeared, equalizer back on, the distortion reappeared, not acceptable, this by the way with no audio source selected yet, this was just the noise introduced by the equalizer.Still, I forged on, pressing play on a test disc while the sliders were centered and neutral I was surprised how muddy the sound was. Yet, as I started to adjust them I was pleased that I could begin to hear the effects; though be careful, boost the range too much and it distorts, badly. That of course on top of the ever present hiss in quiet passages. So much for "pro" quality. Again, maybe in a club where the audience is more interested in the hips shaking than the quality of what's being heard; for some its likely not a big deal but in my living room, this distortion isn't cutting it.Finally, one other thing, the spectrum analyzer, it works great however, the bars spell out "equalizer" as they reach further up the range, gimmick! I could have done without that. Not a deal breaker but it gives off a cheap feel in my opinion.So, where did this leave me? An equalizer that introduces distortion as levels increase, that has a very audible and persistent hiss, oh, and lets not forget the need once gain for sunglasses to save my retinas. You can probably guess what came next; yes, disconnected and back to Amazon it went.Honestly, I could almost deal with the searing blue lights, the gimmicky "equalizer" spelled out in the spectrum analyzer however I have no tolerance for obvious, audible hiss and distortion. I don't know, maybe in a club the razzle-dazzle of bright blue lights are more important than distortion free music. Its odd that in this age of digital music everywhere and anywhere, its getting harder and harder to find quality audio components. Most are home theater set-ups or at this point online only sales. If anyone has suggestions for an equalizer that doesn't blind and sounds good, I'm all ears.

I could not get it to work with my existing audio equipment. It may have been a skills deficit on my part, but I gave up after considerable effort.

The plexyglass was scratchedand the outside edge all around the window was cut poorly and jaged edged. All the filter level controls are cheap and flimsy with no dentent in the center to reset them. The controls' design and outputs and inputs were the only thing I liked about it, but pictures can be deceiving. I never bothered to plug it in and attach my components to it. I gave it to my neighbor and told the person it's yours to do what you want with. I know what quality is and I am very dissapointed that the manufacturer would even consider the design engineers project as something to produce and market. Why didn't I return it? You don't return junk you just remember the name brand and chalk it up to a learning experience.

I'd recommend looking elsewhere. I had this unit for a month, then returned it for a full refund. Love Amazon's policy here, really provides protection from an outright bad or misleading purchase. The equalizer looks cheaply made and the blue LED's (and there's a whole bunch of them) light up the whole room and burn your retina's when you look at them. There's no ability to dim them either. The LCD bar graph looks cheap, too, and light bleeds between graph bars. Didn't hear a lot of adjustment in the audio until I engaged four or more frequencies to make any noticeable changes. But, worst of all, as soon as you bring the EQ on-line, it adds a very noticeable hum to the audio which only gets worse as you increase the volume. Real piece of junk. My suggestion to anyone who wants a seriously good quality stereo graphic equalizer is to search Craigslist or eBay and buy a real vintage unit that was made in Japan or the US in the 70's and 80's. That's what I ended up doing and it sounds great. As long as the sliders aren't dusty or noisy, these units will last forever. Don't compromise by buying this new Chinese imitation junk, buy the real deal and buy vintage!
