[Upgraded] VFD Audio Spectrum Analyzer Bluetooth 5.0 Receiver 3.5mm AUX Selector (Silver)

Easy to setup and it works like a champ! Now I can zone out on lights. The remote is nice otherwise it would be hard to operate.

If you're not afraid to experiment with the remote control, you can figure this thing out. The instructions are quite lacking. I don't have anything plugged into it. I just used the microphone, don't want to run my signal path through something cheap like this haha! Haha! I mainly bought it for the clock because I really like these types of displays. And as a clock it's awesome. It does have some nice options for the spectrum analyzer and it does work well for that. With the microphone. It's just rather cryptic on how to use it. Could have used with a much better labeled remote control rather than a generic one. But for the price I paid I guess it's to be expected. I really enjoy having it though, looks really good. Just sitting there displaying the time and looks nice when it's in spectrum analyzer mode. Just love these type of vacuum fluorescent displays.

Works very well. Very high quality spectrum display with a solid and meticulous build. Looks great in a lit room, but really shines in the dark. Pure retro nostalgia (which is what it was bought for)I love this company's products. Coolest audio equipment there is bar none.

The media could not be loaded. Watch the video. In short it's great, but it takes a few moments to understand the potential functions because the manual isn't the clearest thing in the world. It's not impossible to understand like some reviews might imply, but it's not something non-tech savvy people will figure out quickly.Pro's: Best value to size to function ratio in my research into spectrum analyzer desk devices. Looks awesome, and is accurate and responsive. Has ton's of potential configuration choices. Absolutely worth the money."Con's": The instructions aren't the best. ABSOLUTELY need the controller to set it how you want it (most of the functions are only accessible from controller, including time set). External microphone setting indeed works, but the bars won't be anywhere near exact and show as bass heavy.*USE AN ACTUAL INPUT for accurate bars and a better look tbh.*Can't confirm if you can switch off military time to 12h, as I haven't figured that out yet.Again watch video for demo. 4 stars potentially because until a few things are made easier or more clear, the product won't take off as fast as it could. But still giving 5 because I love it and it's a good deal.

The media could not be loaded. Just like one of the reviewers who shared a video, this thing is great. He is right in saying the MIC alone function is horrible. Since I use my BT from my PC to send audio to my receiver, all I had to do was get a rca adapter to 1.5m stereo out to IN 1 or 2 of the spectrum analyzer. I plugged the rca side into my zone 2 pre out and the other end into the spectrum analyzer. then turn up the volume on zone 2 since most don't utilize zone 2. it works great. be sure when you receive this, it has the remote as it does simplify things when setting up.****update**** 2-27-2025 the product is now failed and no longer powers on. I've tried to reach the company with no response. save your money and do not purchase this item. there is no product support.****update*** 3-9-2025 after many days of no response I added the number on their web page to WhatsApp and reached out. Someone after a couple days responded but by this time I managed to get Amazon to refund the item and send the failed one back despite they charging me for a damaged item? Makes no sense. This company just sent out a replacement with out charging me. I appreciate their help and kindness to send a new one. I adjusted my review to 5 stars because they deserve it despite the initial no to slow response.

I like the features and visuals. Good item. Not many to choose from in the market. This one is good on size and value. Doesn't take up too much desk space. I paired it with VU meter, shown on right side. Seller should add more similar projects, I would buy from again in a heartbeat. I do wish time could be shifted to 12 hr vs 24 hr. I would also like to buy other colors, amber would be nice. I don't mind the slightly confusing UI, I just set it and forget it. Overall very happy with product. Thank you.

Has a lot of settings to play with and overall I'm happy with it but there are a few simple things I thought would make it a bit better.1. Option for 12hr time (24hr only from what i can tell)2. Power supply can add a lot of noise to aux. For the price including a usb power supply should be obvious especially since using the wrong one can make the product seem broken.3. The metal ends are nice but the plastic cover fits loosely making the product feel cheap. Some foam or silicone glue in the gaps would fix this.Overall as someone who has recently become obsessed with vfd displays this thing is really nice. Definitely have to read the instructions to set it up properly but once you do it's a cool desk toy.

Well, I knew well enough to not set very high expectations, but when then this device truly disappointed me. First, it took multiple steps to get it recognized by my av receiver as a BlueTooth device. Once it was connected, I played some music but the spectrum analyzer display barely registered it. Perhaps this would work better with line-in or mic, but I picked this specifically for the BT connectivity.Another disappointment is the LED display, which tried to show the clock in blocky numbers. Again, this was worse than my already low expectations.
