1. Introduction
This manual provides essential instructions for the safe and efficient use of your Rakstore XH-M562 TPA3116D2 Mini Digital Audio Amplifier Board Module. This compact, dual-channel Class D amplifier is designed for various audio projects, delivering 50W + 50W output. Please read this manual thoroughly before installation and operation.
2. Safety Instructions
- Power Supply: Use only a DC 12-24V power supply. Exceeding this voltage range can damage the module. Ensure correct polarity when connecting power.
- Environment: Operate the module in a dry, well-ventilated area. Avoid exposure to moisture, dust, and extreme temperatures.
- Handling: Handle the circuit board with care to prevent damage to components. Avoid touching exposed circuitry while powered.
- Installation: Ensure all connections are secure and correctly wired before applying power. Incorrect wiring can lead to short circuits or damage.
- Ventilation: Although a mini amplifier, ensure adequate airflow around the module, especially during prolonged operation at high power, to prevent overheating.

5. Setup and Wiring
Follow these steps to correctly connect your amplifier module. Ensure the power supply is disconnected before making any connections.
- Power Supply Connection:
- Connect your DC 12-24V power supply to the VCC (positive) and GND (negative) terminals on the board.
- Observe correct polarity to prevent damage. A common mistake is reversing positive and negative.
- Audio Input Connection:
- Connect your audio source (e.g., smartphone, MP3 player, preamplifier) to the audio input terminals.
- Use INL for the left channel audio input, INR for the right channel audio input, and GND for the common audio ground.
- Speaker Output Connection:
- Connect your speakers to the output terminals.
- For the left speaker, connect to SPL+ (positive) and SPL- (negative).
- For the right speaker, connect to SPR+ (positive) and SPR- (negative).
- Ensure speaker impedance is compatible with the amplifier (typically 4-8 ohms).
After all connections are made, double-check them for correctness before applying power.
6. Operating Instructions
- Power On: Once all connections are secure, connect the DC 12-24V power supply to an electrical outlet. The module will power on.
- Audio Playback: Start playing audio from your connected source device.
- Volume Control: Adjust the volume level directly from your audio source device. This amplifier module does not include onboard volume control.
- Power Off: Disconnect the power supply from the electrical outlet to turn off the module.
7. Maintenance
- Cleaning: Use a soft, dry cloth to gently clean the module. Do not use liquid cleaners or solvents.
- Storage: Store the module in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- No User Serviceable Parts: The module contains no user-serviceable parts. Do not attempt to disassemble or repair it yourself, as this will void any potential warranty and may cause further damage.
