EQ570 Audio Equalizer Black

What I am using for: I have this in between a high quality Bluetooth receiver and my amplifier in order to provide the ability to apply simple equalization to all of the audio output from my iPad to my HiFi. It has many other uses in terms of placement in a system.** More detail below, but update after having this for a week. I am super pleased. It does just what I hoped and does it very well. I recommend this highly.I have a Auris Blume HD Long Range Bluetooth 5.0 receiver connected to my amplifier. It has both analogue and digital out. I play music from my iPad through the Audi’s receiver into my HiFi system. I have eclectic music tastes spanning decades, and wish much of the older music (pop, rock, etc.) had a fuller sound and more bass on the low end. Much of the current music has loads of it (maybe too much for some things. I wanted a way to be able to switch the sound profile of my HiFi by merely using the remote. And this totally does the job. Here’s how:I connected the analogue signal out from the Auris Bluetooth receiver (which, by the way, accepts the high quality ACC data from an IOS device and it (the Auris) has an exceptional DAC in it). My amplifier does also.I took this Rolls equalizer and put is in between the output from the analogue outs from the Auris and the amplifier. My amplifier does not have a tape monitor switch I could use for this function (looping the equalizer) but I have the optical/digital out from the Auris going into the TV in on the amplifier accepting digital input and the analogue from the Rolls into the CD input on the amplifier. I set the lowest and highest frequencies up just a bit on the Rolls to have ot function, essentially, as a loudness compensation, with a little more oomph on the bass the added bump on the treble.Now, I can switch back and forth between the TV input (just the label for it—it’s the optimal signal from the Auris, from my iPad) and the CD input (the analogue signal from Auris modified by the Rolls settings) and can instantly switch my sound to a fuller one for certain older music, or for when I want a loudness type function for listing at lover volume.This all works perfectly because, as they note, the Rolls will accept input from anything that is line level analogue and send it on to your amplifier with your modified sound. Wonderful.The rolls seems very well made, sturdy. Someone noted how small it is. It does not seem that small to me. The knobs are reasonable size, have very “feelable” detents for knowing where the neutral is, and they seem to all adjust exactly the ranges that are specified (I tried testing this in a simple way with a test music album).This works. It has many possible uses and it perfectly does what I had hoped it would. It also has a kind of cool retro look to it, which I like a lot.

I bought this for a Holiday party and it was a 100%-success! I needed to send TV audio into a pure audio amplifier with no EQ to play a YouTube video of my band's recent Christmas gig to 30-guests. Without the EQ the tone lacked bass and brilliance. With the Bellari I got rich, clean bass and shimmering brilliance! ** This is the only EQ I've seen with stereo 3.5mm input/output, which is exactly what I needed! ** Finally: Someone wrote that they wished the Bellari had a volume knob because they wanted to boost volume. You CAN greatly boost volume with the Bellari! When any knob is at the midpoint, it's not reducing or boosting. To get more volume, just turn any or all four knobs above the midpoint!

I was hoping to use this little EQ to improve the sound of an inexpensive receiver/speaker combo. But there was no way to reduce the input gain to make up for the gain increase I was adding with the EQ controls. So it quickly introduced distortion if I increased the bass more than a tiny bit. I had a similar problem using it between a tape output and a Bluetooth transmitter sending signal to a set of outdoor speakers. It bums me out because there is such a dearth of good, inexpensive, simple to use EQs these days. And it seems like it would be incredibly simple for Belari to add a 15 dB+/- gain control to make this unit infinitely more useful.

I wanted to love this product. It's made in the USA, looks and feels beautiful. It does what it's supposed to do, eq levels work great and music is enhanced.So what's the issue? This thing makes a horrible noise when turned on and when playing CDs and vinyl it suddenly gives scratchy loud quick noises from time to time that could damage your speakers. I am not the only one go look at the comments on YouTube where they review this product.It's a no no for me.

One, loved the owners manual... let your ears do the adjustments. A few months ago I began just for fun, putting a system together on the cheap. Two channel old school with the little Cambridge 25 watt per chan. running psb alpha 3s.sources tweaked out Dennon 300? Ttbl, Pioneer cd player ? ... love audiophile recordings, and am doing a top 25 vynyl fave all time collection..fun for us old guys.. Early 60s to current..well the Bellari eq simply blew me away...i really didnt expect the dynamic sound stage difference. Or how male voices could be brought out.El wifo after my venture into high end audio 2000 +-. Dozens of questions "do these connects sound warmer." She was relunctant to play the ear. Remarkably though, gave a thumbs up to the Bellari addition..(i think it was a thumb) serously it made a big difference... she even remembered the no adjustments on my Sim Audio Moon amp. And why..of course. I explained, nope this time arond we can just have fun like we did many moons ago.. Not sure why the little red eq did what it does.A tip o hat to the folks down Salt Lake way. Great build quality...The new little system sounded good before.. Actually outpunching its wght."old man rambling alert" had a Kenwood system late 70s... 35 watts per driving 4, yes 4 Bose 301s.. which could make your ears and nose bleed. Also get you kicked out of an apartment or 2.. so, no problemo on watts. Just be careful of speaker choice.. i still like listening to some select music loud..better, loud and rich. Some of my older albums sounded a bit weak in middle ranges.So am very happy with this purchase.
