Features:
- Green fluorescent display
- Support pickup
- 10 display modes
- Dual-channel and mono display
- With a DC 12V socket, 5V type-c port, audio input port and a wiggle button

- There is an air leak detection device in the lower left and upper right corners of the display. If there is an air leak, these two places will turn white

FAQ:
Some users have reported that there is light at the bottom of the screen when no music is playing. This situation is caused by the user's unclean music signal, generally due to the use of an unclean power supply. Including the 12V power input of this product, and digital audio devices such as Bluetooth speakers and USB speakers, the audio of such devices contains a large amount of fundamental frequency noise. The noise of some low-end products can heard from the speakers. The method to judge the extraneous noise: short-circuit the input terminal to ground, and the screen should not have any display.

Application:
- Used for home audio modification, DIY, car modification, and computer modification.
- It can only be used indoors and applied to non-high-frequency vibration sites.

Package Included:
- 1 x Spectrum Display

 

Attention:
- If you are using an AC power supply, convert it to DC and use it independently. When the display is powered by DC, GND needs to be the same as the GND of audio.
- Please read the text on the PCB, confirm that it is correct, and then power it on.

Question and Answer:
Q: Some speakers use BTL output or Class D function, and the two ends of the speakers are not grounded, can I use such speakers?
A: Yes. There are two wiring methods: 1. Use a power supply that sharing COMMON with the power amplifier, such as the power supply on the car, at this time, connect any speaker cable to Lin or Rin, and GND does not need to be connected. 2. A separate power supply is used, at this time the power supply and the power supply of the speaker amplifier are isolated, any one wire of the speakers is connected to the GND of the power amplifier and then connected to the Lin and GND of the screen. If only one speaker is connected, you can also connect the two speaker lines to the Lin and GND of the screen.

More Information:
There are 3 colors on this screen, with orange border on both sides, milky white bars at the bottom, and green in the middle part showing the spectrum. If you want to display white, use a brownish-red light shield.

Attention:
- For wiring, DC 12V power supply is recommended.
- The audio input is audio in terminal and GND, which is compatible with the audio output of general equipment, and the audio output is audio out and GND, it is recommended to connect one of the wires of the power output of the speakers, because the audio input GND of this PCB and the GND of the 5V power supply are connected. If this display module is installed in a device, ensure that the GND of the power supply and the GND of the output audio are also the same or completely isolated.
