Important hint

1. The maximum power depends on the power supply voltage power and speaker impedance, THD = 0.1%, RL = 4Ω VS = ±28V;

2. If it is a 4Ω load, the voltage of the transformer should not exceed double AC20V to avoid unnecessary losses;

3. Please pay attention to monitor the temperature of the heat sink during use, if necessary, it is recommended to use a fan to assist heat dissipation;

4. The design size is for reference only, and there is a deviation from the actual product, please refer to the actual product.
