## Description

8 Kinds of Classic Display Modes: Mode 1: Columnar mode Mode 2: Columnar with peak holding mode Mode 3: Columnar with peak, peak upward moving out mode Mode 4: Mirror mode, from middle to both sides Mode 5: Single point mode Mode 6: Peak upward moving out mode Mode 7: Single peak mode Mode 8: Mute with all lights on mode(available for testing LED) Instructions: 1. Please insert the attached connector USB terminal to your computer USB interface, 3.5mm headphones by audio branch into the computer or other device's headphone output jack, the other end of the branch connects audio equipment; 2. Gain description: 1-3 levels are gain attenuation, 4 level is 0 gain, 5-6 levels are gain amplification. Please adjust input volume and gain to make the display amplitude at an appropriate range (default value 3); 3. If happened to full screen display, please reduce the gain or input volume; if the display still dances when no sound source input, please replace the power supply to test or use computer USB terminal as power supply; 4. If the audio input terminal needs to be connected to amplifier output or speakers, please use capacitor and potentiometer to attenuate the signal, and please make sure that the audio signal input voltage should be within 5V, or the sound spectrum analyzer will be damaged. Note: Please do not use counterfeit phone chargers, unstable power supply or other power supplies which have large ripple, or it will cause background noise or damage to the audio analyzer. Package Includes: 1x Music Spectrum VU Tower

Review: This is my new favorite LED display! - Simple, easy to use and paired w/a 2nd easily. Also loved the different modes it has. You have to rate this for the price and ease of use. You plug it into USB power and then you then split the signal w/a headphone jack. There aren't much for options for audio, but you can make it work w/splitters, or if you have a real audio device w/multiple outputs you can just plug it into a secondary output. Only negative I would say would be the color choices for the top end, it should go up to red/orange on top vs the green/blues it does. That would be my only complaint, other than that it is some inexpensive, very well crafted eye candy for my computer setup.
Review: Cool science project - not a real show piece. - It works well and is a very cool looking tower “display” but it lacks a truly finished appearance, more like a science project. It’s fine for a computer or gaming desk but not really something for the living or family room when guests would see it. A case, especially an option for a wooden case, with openings for the translucent “bars” would help make it a solid product. It reacts to the music but not using tonal accuracy. There is no difference between a bass note and a loud guitar solo visually. $50 is simply too much for this product.

## Questions & Answers

**Q: Will it  with Any audio  output**
A: The device has a single mini-USB input into the tower. The other end of the cable is split between a USB end (for powering the lights) and a male 3.5mm stereo headphone jack that plugs into the back of your computer for the audio input. Mine also came with a 3.5mm splitter, so I was able to use that to output sound to both my speakers and to the tower.

**Q: Does this connect to a sound bar?**
A: No

**Q: Can this be used with a tablet and a blue tooth speaker?**
A: Could never get mine to work. Be carful

**Q: Will this work with headphone amp connected to amp>dac>laptop? if so, how would you connect two units to this chain?**
A: I used a USB Expansion Port!

### ⭐⭐⭐⭐ Let there be Lights!
*by E***D on December 3, 2019*

this little thing is pretty darn cool. it's about 8" tall and 2" wide, so it won't take up a lot of room on a desktop. It works as described -- real-time audio spectrum analyzer converts sound to light. It comes assembled; all you have to do is connect the usb cable into the tower and the other end of the usb into a computer, and connect the 3.5mm splitter cable to your speaker output line. 4 stars because 1) the supplied instructions are in Chinese and aren't very helpful. Luckily, these same instructions are also on the product description page. So you can copy, cut, paste, and print them and you're good --I also saved a copy to the cloud in case i ever lose the printed copy. 2) The USB cable is super-short, and the 3.5mm jack end--which plugs into your computer and forks from the USB connector-- is only about 2 inches. This limits connectivity. I have a headphone amp/DAC as an external sound card which outputs to my powered speakers. I was able to plug the splitter into the output jack and plug in the unit's cable and the speaker cable into my DAC/amp. But the length of the cord prevented me from trying other configurations. it's not long enough to plug into the USB on the back of the computer and the front headphone input at the same time. The cord also wasn't long enough to place it on the right side of my computer, or to plug in into the front panel USB and the headphone inuput while also placing the unit on my desk where i can see it. I had to plug in the USB to an external USB/card reader which sits on the top of my computer, which robs me of one of my USB 3.0 ports. So, depending on your desktop set-up, this could be problematic. It may be possible to buy a longer aftermarket cord--you would need micro-USB to USB male + 3.5mm--but it would have been nice to have a longer cable, like a 6ft cable, supplied. 3.) it would be a chore to connect two units together. You would need 2 free USB ports and 2 free headphone ports, although i suppose if you use a headphone amp, you can use the splitter to run sound through both units on one port. But then you would need a longer cable for the second unit. That said, for what it is and at this price, it's a pretty fun gadget which brightens up listening to music on dreary days immensely. Can't wait to use it at night. I didn't try out all the functions, just tested it at the default setting, so i may edit this review after doing so. EDIT: apparently it is possible to separate the audio channels into R/L stereo, which you may want to do if you get two units. You'd still need to figure out the input situation and get a micro-usb splitter and a longer cable. I may do this eventually. This unit also appears to be exactly the same as one by another seller which is more expensive.
