Setup Instructions
Follow these steps to correctly set up your amplifier board:
- Power Connection: Connect a DC 9-24V power supply to the DC power input terminal. Ensure the polarity is correct.
- Speaker Connection:
- Connect your left and right channel speakers to the 'Left Channel' and 'Right Channel' output terminals.
- Connect your subwoofer to the 'Subwoofer' output terminal.
- Ensure speaker impedance is compatible (typically 4Ω or 8Ω). Refer to the 'Specifications' section for power output details based on impedance.
- Audio Input: Choose your desired audio input method:
- Bluetooth Input: The board will automatically enter Bluetooth pairing mode upon power-on.
- USB Input: Connect a USB drive containing audio files to the USB input port.
- AUX Input: Connect an audio source (e.g., smartphone, PC) using a 3.5mm audio cable to the AUX input port.
- Initial Control Settings: Before playing audio, set the 'Main Volume Control', 'R&L Treble', 'R&L Bass', 'Subwoofer Volume', and 'Subwoofer Frequency' knobs to their minimum positions to avoid sudden loud sounds.

Troubleshooting
If you encounter issues with your Daakro YS-S100L amplifier board, refer to the following common problems and solutions:
- No Power:
- Ensure the DC power supply is correctly connected and providing 9-24V.
- Check if the power adapter is functional.
- Verify that the 'Main Volume Control' knob has been long-pressed to turn on the device.
- No Sound Output:
- Check all speaker connections for proper polarity and secure fit.
- Ensure the volume knobs (Main, Subwoofer) are not set to minimum.
- Confirm the correct input mode (Bluetooth, USB, AUX) is selected.
- If using AUX, ensure the audio cable is fully inserted and functional.
- If using Bluetooth, ensure your device is paired and playing audio.
- Bluetooth Connection Issues:
- Ensure the amplifier board is in Bluetooth mode.
- Move your device closer to the amplifier board to ensure it's within the 16.4ft range.
- Turn off and on the Bluetooth function on your device and the amplifier board.
- Disconnect any other Bluetooth devices from your audio source.
- Distorted Sound:
- Reduce the input volume from your audio source.
- Check speaker impedance compatibility.
- Ensure the power supply provides sufficient current for the desired output power. Insufficient power can lead to distortion at higher volumes.
