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

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.

Looks and works great, happy with the purchase.

Solid build. Looks and works great. Needs partial assembly. Assembly insructions non-existent, but with a bit of trial & error and common sense, easily accomplished. Set up insructructions murky, unclear and disorganized. Wish manufacturers would learn to write clear insructions.

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 spectrum display I have been wanting since my teenage years!It has been working flawlessly since the day I powered it up with a Dell power supply.

This has potential but it is a royal pain in the end to figure out how to change settings. As another reviewer stated the instructions "are clear as mud". I don't need a real spectrum analyzer for producing music or measuring room acoustics, I only wanted this for the dancing lights when listen to music. First of all, this thing is SENSITIVE on mic mode and even displays the popping sounds of my water heater in the garage and pics up the sirens of the paintball field nearly half mile away. It does look fantastic. However, one day when using as a spectrum analyzer it switched modes on its own to a full display of solid light bars. I've spent at least two hours trying unsuccessfully to get it back to where it was. The manual is USELESS. In one of the modes it makes a loud buzzing sound which gets picked up by the mic. Resetting to the factory settings does not return it to the original SA setting that was configured right out of the box. If I can't figure this out in the next day or two I will just return it. Update: I will definitely be returning this unit. I attached a picture of the unit working with the bars moving from the top, down. I am using this in mic mode, not AUX mode, in a quiet environment with no music or other noises. Yet, the spectrum analyzer is dancing as if it is responding to actual music LOL. Nah, I'm not keep this unit.

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!

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.
