Review: Fun Addition - Maybe there's a good way to use this is an actual calibrated analyzer but I'm just using it as a vibe piece. Has a bit of a vintage 90's appeal to it. Turns into a clock with calendar when not playing sound. The included booklet was fairly useless and the menu isn't intuitive but if you spend 10 minutes playing with the controls, you'll figure it out. Might try to build housing for it out of wood at some point but even as is it still looks pretty good on a shelf.
Review: Great item! - This is a great buy even if only for show. Highly recommend!

## 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"
