How to Use the XH-A397 4-Channel Class AB BLE5.0 Digital Amplifier Module:

The XH-A397 amplifier module is easy to set up and integrates smoothly into various audio systems, offering Bluetooth, AUX, and USB input options for versatile use. Below are the steps for setting it up and using it:

1. Powering the Module:

• The XH-A397 requires a DC power supply between 12V-18V with at least 5A current. Connect the power adapter’s positive and negative terminals to the corresponding terminals on the amplifier board.
• Ensure you have a stable power supply to avoid audio interruptions or damage.

2. Connecting the Speakers:

• The module supports a 4-channel output (50W per channel). Connect your speakers to the output terminals marked L+, L-, R+, R- for the left and right channels.
• Ensure that the speakers’ impedance is within the supported range (4Ω-8Ω) for optimal performance.

3. Choosing an Input Mode:

The XH-A397 offers three input options:

• Bluetooth:
  • Power on the module and enable Bluetooth on your device (phone, tablet, etc.).
  • Search for and select the device named “BT-Audio” or similar.
  • Once connected, you can stream audio wirelessly to the amplifier.
• AUX:
  • Use a 3.5mm AUX cable to connect your audio source (e.g., smartphone, PC) to the AUX input jack on the module.
• USB:
  • Insert a USB flash drive containing your audio files into the USB port on the amplifier.
  • The module will automatically start playing the audio from the flash drive.

4. Adjusting the Volume:

• The XH-A397 has onboard volume control buttons. You can use these to adjust the output volume according to your preference.
• For devices connected via Bluetooth or AUX, you can also control the volume directly from the source device.

5. Fine-Tuning and Troubleshooting:

• Make sure all connections are secure and avoid placing the module in environments with excessive heat or moisture.
• If you experience any issues with sound quality, check the power supply, speaker connections, and input source to ensure everything is properly configured.

6. Using the Module in Different Applications:

• Home Theater Setup: Connect the amplifier to your home speakers and stream audio via Bluetooth or AUX for an immersive experience.
• Car Audio System: Install the module in your vehicle, connect the speakers, and enjoy wireless streaming with Bluetooth.
• DIY Audio Projects: Use the versatile input options and robust output to enhance your custom audio builds.

Important Tips:

• Always power off the module before making or changing connections.
• Use speakers that match the amplifier’s output capacity (4Ω-8Ω, 50W per channel) for optimal performance.
• Keep the module in a ventilated space to prevent overheating.
