Blue LEDs at blinding "TOO BRIGHT!" No dimmer or off switch.

Blue LEDs at blinding "TOO BRIGHT!" No dimmer or off switch.
This EQ works as expected, good sound, however the LEDs for each pass channel slider control is TOO BRIGHT! They are blinding bright; you cannot look at the unit to make adjustments. See the picture I attached; I placed rubber covers over each pass channel slider to eliminate the LEDs. The unit should have a dimmer or OFF switch for these LEDs.

CONS.. very bright . a way to switch off the lights would have been helpful. PROS. anyone finding the problem with modern receivers not having a tape loop/monitor option, this equalizer provides a solution to that problem. i hope more EQ companies learn from this model. i realize some people get faulty equipment out of the box. mine did not seem to suffer from any issues. the sliders seemed to be solid and firm. the spectrum analyzer isnt perfect , but i am using it on a pyle 300 watt blue tooth receiver which has one so i dont mind. It sounds fantastic in my humble opinion, does what you want it to do, so to sum up it is an EXCELLENT buy, for the price.

I received this equalizer yesterday and it sounds great as for the bright lights I just dumped my old technical Pro which I believe is the same unit as this one except that didn’t have a spectrum analyzer. I had that unit about 10 years and shortly after I got it the bright blue lights all started dying out and I only had two left so hopefully that doesn’t happen to this unit. It does wonders for my system it runs my CD player and my iPod personally I think it’s a great unit for the money.

Ok,so as ALL the other reviews have stated,this thing is BRIGHT,REALLY REALLY BRIGHT!Really can't understand why it's so bright;not really an issue from me as it's om my shop stereo.But if I had it installed in the house it would be just too bright to use.So be warned.As to the sound quality some other reviewers have said that it doesn't work at all.Mine does actually work,not great,and certainly not as good as the Technics eq it replaced.But for the $$ its ok.Other reviews have said that the center 'frequency' display does not accurately depict what s actually being played,and I've got to agree with that.It's just some bouncy lights made to entertain and distract the buyer from the fact that he just got hosed.And mine have stopped working altogether so there's that.I bought mine as an Amazon return.Had i paid full price this thing would be going back!

YOU'VE BEEN WARNED!

October 12 2020-So I bought this POS last September.Sometime between then and now the center display quit working,then working sometimes,sometimes not.,oh well.Then this morning I find the left channel has quit working when in EQ mode.Still works when bypassed but that kinda negates the usefulness of a GRAPHIC EQUALIZER!

A one star review is the lowest I can give this so called equalizer.

Just sent your money on fire.You'll get more enjoyment out it that way.

3.0 out of 5 stars Display is NOT a spectrum analyzer!
Reviewed in the United States on April 29, 2021

The display is described as "Multi-colored spectrum analyzer display" but it is neither. The display is all bright blue and it s not a spectrum analyzer. Instead, all the bars of the display go up and down in unison.
The unit has a mechanical hum from the power transformer and the display is much too bright. The power switch does not turn the unit off, it only turns off the display. The power transformer and internal electronic components run very hot, even when the unit has been turned off for hours. I returned it and do not recommend it to anyone.

I had to replace my 40 yr old Pioneer equalizer and spent a lot of time searching. There are not many products out there for the casual listener who wants great sound and more control over what they hear. I love my Harmon/Kardon receiver and my Atlantic speakers/sub, and I was looking for an easy to connect, quality product. I took a chance on this equalizer and am glad I did. I can't hear any distortion and the adjustments I make are noticable, allowing me to get the sound just right for my ear.

4.0 out of 5 stars Sounds great just not built great
Reviewed in the United States on April 5, 2016
Verified Purchase
The equalizer surprisingly sounds very good. After trying to unplug an RCA and the jack pulling completely out I didn't expect too much and was kind of disappointed but I changed cables and inputs and it worked great and sounded very good. I read some of the other reviews about the brightness of the lights. I thought people were just being too picky. My apologies. You can be sitting in a pitch black room with the EQ on and still see what's in the room. RIDICULOUSLY bright. The spectrum has no line level adjustment so if you want to see the analyzer work you have to have it turned up really....really loud. I have it hooked up to a Harman/Kardon Signature Series receiver and amp and love the sound quality. It's just not the highest build quality.
