Dual Channel LED Sound Level Meter – Stereo Music Spectrum Analyzer for Home and Car Audio Display

I already got two of them It has several effects and colors it looks and works amazing.

This thing looked like a great addition to my setup but it arrived with zero instructions and not even a model number. I can’t even find it on the company’s website and there’s not a speck of online info or support. I found one YouTube video that just showed someone using it but no explanation of what they were doing. There’s a QR code on it that takes you to a page written entirely in Chinese (I think). Maybe if I could read Chinese I could get it working and it would be great but I’ll never know. I give up and it’s going back

Love getting to monitor my internet radio stations visually.

The device works as expected using the included cables. After connecting the USB A end to a power source and the TRS female connection to a stereo audio source you can monitor the sound levels as expected. Unfortunately, using the mode button to switch between AGC and dB levels is extremely difficult to figure out without a user manual. Through trial and error, I found that holding the mode button until 3 appears seemed to toggle these modes. The QR code on the back of the device is not helpful and an online manual cannot be found anywhere.

Sturdy build but a bit heavy. No instructions included and website link doesn’t work, I couldn’t make the display change color as advertised. The cable combining power and audio input is included.

This lights up when you start it, but that is the end. No audio input nor microphone. Comes with a cable, yet no connection port. This is a a worthless hunk of metal. -10/10 Why you waste my time?!?

This is a fantastic VU meter. It is exquisite built and has a lot of features. It provides feedback on the screen when changing settings. A lot of things to play with: speed, sensitivity, color scheme, brightness, etc. Fantastic!
