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.Bought this in 2020. It's 2025 and wanted to come back and say how perfect this has been for me. Never a hiccup or issue. Does the job I wanted done and flawlessly.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.

The Bellari Audio EQ570 Audio Equalizer is a game-changer when it comes to enhancing the sound quality of your headphones. As an avid music listener, I know that some people may be skeptical about EQing headphones, but the EQ570 has completely transformed my listening experience.I tried the EQ570 on a variety of headphones, including my Focal Elegias, SHP9500's, Jubilee58x, and Grado 325x, and I was blown away by the difference it made. It's amazing how much more detail and depth you can hear in your music when you have an equalizer like this one. The EQ570 breathed new life into my headphones and made my listening experience so much better.What I love about the EQ570 is how easy it is to use. It has a simple layout with intuitive controls that make it easy to adjust the EQ settings to your liking. The rugged metal chassis also ensures that it's built to last and can handle regular use without any issues.Overall, if you're someone who loves music and wants to take your listening experience to the next level, the Bellari Audio EQ570 Audio Equalizer is definitely worth considering. It's a powerful and versatile tool that can enhance the sound quality of a wide range of headphones and make your music sound better than ever before.

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.

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.
