Audio Input (Optional): The device can pick up sound via its built-in microphone. For direct audio input, connect an audio source (e.g., headphone output from a device) to the 3.5mm audio input jack.
Placement: Place the spectrum display in your desired location. Ensure it is stable and has clear access to sound if using the microphone input.
5. Operating Instructions
Once powered on, the device will immediately begin displaying visual patterns based on detected sound. Use the control buttons and potentiometer to customize the display.
Mode Button: Press the 'Mode' button to cycle through different display patterns and effects.
Brightness Button: Press the 'Brightness' button to adjust the intensity of the LED lights.
Speed Button: Press the 'Speed' button to change the animation speed of the spectrum display.
Sensitivity Adjustment Potentiometer: Use a small screwdriver or your finger to rotate the sensitivity adjustment potentiometer. Turning it clockwise increases sensitivity, making the display react to quieter sounds. Turning it counter-clockwise decreases sensitivity, requiring louder sounds for a reaction.
All adjustments made using the function buttons and potentiometer are automatically saved and remembered even after the device is powered off.

6. Maintenance
- Cleaning: Use a soft, dry cloth to gently wipe the surface of the display. Do not use liquid cleaners or abrasive materials, as they may damage the LEDs or casing.

- Ensure the Type-C cable is securely connected to both the device and a working 5V1A power source.
- Try a different Type-C cable or power adapter to rule out cable/adapter issues.
- Display Not Reacting to Sound:
- If using the built-in microphone, ensure the device is placed close enough to the sound source and that the volume is sufficient.
- Adjust the sensitivity potentiometer (clockwise to increase sensitivity).
- If using the 3.5mm audio input, ensure the cable is properly connected and the audio source is playing.
- Display Patterns Seem Incorrect or Static:
- Try pressing the 'Mode' button to cycle through different display patterns.
- Adjust the 'Speed' button to see if the animation changes.
- Adjust the sensitivity potentiometer.
- No Other Features Available:
