Description:
This is a high-quality subwoofer amplifier board. It adopts high-efficiency half-bridge power supply, with 120V and 230V transfer switches, suitable for global use, and the power supply margin is quite large, and the ripple is lower than the traditional transformer power supply. The power amplifier output also uses MOS high-current tubes output, which achieve a true 1% distortion of 350W, and the control is amazing. The front stage adopts the current high-tech in the subwoofer industry, using dynamic EQ algorithm, high speed, low diving, and high control. A low-cut is also designed, which cuts all the frequency below 18Hz, and converts the energy to the frequency range of 25Hz-60Hz, which makes people sound endless and full of energy. In addition, this power amplifier board is also equipped with a phase-inverted subwoofer and a closed subwoofer switch, so that each subwoofer can achieve good results. The material is solid, with an aluminum back panel, and almost no noise level. It is a rare subwoofer power amplifier board for home theaters.
