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

I was pleased with the quality of this display. The firmware could be a little better written, and the range settings could be better but for the price it’s pretty decent.

Love this spectrum analyzer

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.

Great,product,5 stars plus,I order 0ne more for my car,thank you.

Very useful. It works great no problems.

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!

Hold the up and down until it reads reset then press the middle button.

The media could not be loaded. El equipo funciona muy bien, bastante bonito y funcional. Ahora las instrucciones para el ensamblado toca deducirlo intentando varias veces porque el manual no dice cómo hacerlo, igual es de lógica y el manual que viene podría ser algo más prolijo ya que son unas hojas cortadas y ya. De igual manera es interesante y práctico
