Review: High quality and look good - It is perfectly in sync with the music, and with the included instructions it’s very easy to set up and switch between different modes. The clock setting is also simple and convenient. The build quality is solid. At first, I wasn’t sure whether to use it or not, but I ended up building a custom frame for it under my TV. My original goal was actually to cover the wall holes from a previous soundbar installation. Interestingly, the frame turned out great and even improved the overall look. Now it has a very clean and premium appearance. When the audio system is on, the spectrum display activates, and when nothing is playing it switches to clock mode. I really like it.
Review: Fun! Works as expected. Directions could be a little easier for controls. Looks great though!! - Very fun! Mic is a little sensitive and whether it's rock, rap or vocals - bass frequencies seem to pick up much more than high high notes. I'm sure wiring it directly would make the Analyzer more accurate but I'm not sure of the deninishing return in sound quality. Overall tho - very cool!!

## 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"
