2x400W 220V Hifi Amplifier Board Power Amp Board with Switching Power Supply for Stereo & Mono Modes
The module adopts American HIFI digital power amplifier chip and the German nano silicon LLC power chip as the core. It has been carefully designed for many years. It is designed with on-board high-power LLC resonant sine wave switching power supply. The board has high power, high fidelity, high sound quality, and low noise. It has over-current, over-temperature, and short circuit protection. With speaker relay protection, so there is no shock sound when it turns on and off, which can effectively protect expensive speakers.
