Review: Looks cool. I bought it purely for visual candy for my synthesizer. - Very happy with this product. It works as expected and the display looks good. They only complaint I have is that It’s very confusing to understand how to set it up. Once I finally figured it out it was great. Love that it can take an audio signal or use an internal microphone.

## Questions & Answers

**Q: Is this plug and play unit?**
A: Hello. Yes. It is a finished product. You only need to connect signal input and power input.

**Q: The clock is very annoying! Any way to disable it, so it only acts as a spectrum display? Thanks**
A: Disconnect from headphone jack when not in use.

**Q: when plugged in to a audio source, Ii have 2 or 3 bars flickering like there picking up some interference. any solutions?**
A: Got something similar happening with many bands even when there is minimal audio input. The problem appears to be a poor connection between the 1/8" plug and the socket on the analyser. What I have done is remove the plug, clean it, re-insert it and check. If that doesn't immediately solve the issue, I twist the plug in the socket until I get it to a position that zero input registers nothing on the analyser.

**Q: What are the unit's dimensions?**
A: 7"  x  2"   x 1"
