Frequently Asked Questions
Q: What is the difference between TPA3116D2 and TPA3118D2?
The TPA3116D2 is a stereo (2-channel) Class D amplifier IC; the TPA3118D2 is a mono variant. The XH-M543 uses the stereo TPA3116D2 in a dual-channel layout delivering 2×120W peak output.
Q: Can I use the XH-M543 via AUX only without Bluetooth?
Yes. The board includes a 3.5mm AUX input jack. Connect your audio source via a standard 3.5mm stereo cable. Bluetooth and AUX inputs can be switched independently.
Q: What power supply do I need for full 2×120W output?
Use a DC 24V supply rated at 10A or higher for maximum output. At 12V, output is reduced but suitable for most bookshelf speaker applications. Ensure center-positive polarity.
Q: Is the XH-M543 suitable for car audio?
Yes. The 12V–24V input range is compatible with standard 12V automotive systems. Use appropriate fusing and ensure the supply delivers >3A sustained current.
