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

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.

This is a great buy even if only for show. Highly recommend!

Works as advertised and I really like the rear facing USB C power connector in addition to the side jack that is not mentioned in the listing.

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.

Works outstanding, looks outstanding. Had to youtube for all the settings but it looks great. 2011 Honda Accord

The Spectrum Analyzer itself is pretty cool. Definitely worth the money. A bunch of capability. No regrets there… However, as almost everyone else has commented, the instructions are terrible. Not just a little confusing / incomplete, a lot. They’re really not very useful at all. I got through the configuration of the device as much by trial and error as I did anything else. I mean the instructions are bad enough that many people would want to avoid purchasing this device. Were a but more time and care taken with the instructions, this would be a 5 star review. As they stand, 3 stars is the best that I’d personally stand behind. Sorry Nobsound.

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!

Finally something you can plug in and it works. No app needed, no download and configure, no Bluetooth it just works. Give it power and it works. Absolutely amazing

प्रोडक्ट अच्छा हे लेकिन सेटिंग थोड़ी मुश्किल कंपानी को सेटिंग करके भेजना चाहिए मेरे प्रोडक्ट में ऑडियो इन करने के बाद भी वौइस् पर रियेक्ट कर रहा हे क्या ये पर9डक्ट का प्रॉब्लम हे या सेटिंग करनी पड़ेगी

it took about a minute to put together and I plugged it in and it started working right away and all the displays work, the mic is very sensitive, it picks up the traffic when the window of the room is open.

No nos gusto que es frágil no trai una protección como tal es chiquito hace su función pero si nos hubiera gustado una cajita de acrílico o madera

ya me llego y aun no marcan que ya se me entrego el pedido, lo que no me gusto es que vino maltratado, lo metieron en una caja sin envoltura y se ve se estuvo agitando llego con un boton desoldado y pines todos doblados ( los enderece como pude), lo probe, parece funciona bien.

Working absolutely well. Easy to assemble.
