Nobsound AK2515 Pro Audio Spectrum Analyzer with VFD Display, MIC Input & Advanced AGC - Precise Sound Level Meter for Musicians and Audio Enthusiasts

Very useful. It works great no problems.

I don't write reviews but this thing is far too cool to go without. For anyone who loves electronics, particularly good stereos, this is a must have.Assembly is relatively easy. Just look at the picture and you'll be fine.Mic is the default setting so if you're hooking it up to your receiver, you'll have to go into the programs and change that. Easy too.Absolutely love it. Bought a cheaper piece of crap and regretted that. Spend the money and get this one!

This is a cool analyzer for this price point and is great for measuring the spectrum. I have it hooked up to my turn table and is a great visual. The controls are fairly easy but don't lose the instructions or you may have issues figuring out how to use it.

This is the best $50 I think I've ever spent on an audio device. It's VFD is beautiful and the motion is smooth just how you would want even a high end spectrum analyzer to operate. It has tons of options easily accessed, but don't lose the manual to recall the sequence needed for each option. It's also a clock when not in audio spectrum analyzer duty!

The media could not be loaded. It is well built and with quality exuding. While the instructions are a bit dim... After a while of reading a few times, the device works like a champ! Had it for a year and still awesome!

Darn segments have started to fizzle out after a few weeks. Also its a nightmare to program if you happen to press the wrong button. Hours to get back to stock config.

AS ADVERTISED, ARROVED ON TIME IN GOOD CONDITION, ASSEMBLY NO PROBLEM. INCLUDES EXTRA PARTS FOR ASSEMBLY, GOOD THING , SINCE THEY ARE VERY SMALL. BUT EASY ASSEMBLY. PURCHASED A SECOND ONE .

Good product but menu option they make very complicatedplease any one send me how this menu work any proper pdf or file very very complicated menu options
