XH-M422 TPA3116D2 Class D Double Channel 50W+50W Digital Bluetooth Amplifier

  Configured with advanced modulation systems.

  Bluetooth transmission distance is about 10 meters.

  Transmission distance will be different due to different environment.

  If you want DIY a sound box, it's better not to use a material that has a blocking effect on the bluetooth signal.

  Its high integration reduces the number of components and integrates the natural protection circuit, including overpressure, undervoltage, overheat, DC detection and short circuit protection.
