High quality subwoofer power amplifier board Audiophile cinema subwoofer amplifier board Rated power 200W, maximum power 300W High-efficiency half-bridge precision power supply + high-power MOS tube output With rated power 200W output. It adopts high-efficiency half-bridge power supply, with 120V and 230V transfer switches for global use. And its power supply margin is quite , and ripple is lower than that of traditional transformer power supply. The power amplifier output also uses MOS high-current tubes output, which achieves 1% distortion of 200W, and the control is amazing. The front stage adopts the current high- 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 18Hz, and converts the energy to the frequency range of 25Hz-60Hz, which makes people sound endless and full of energy. In addition, the board uses an aluminum back panel, there being no noise level. It is perfect for home theaters.
