Features:
(1)The newly designed active subwoofer amplifier board is real and effective. The power amplifier part adopts TPA3255 digital power amplifier chip, with a peak power of up to 600 watts/2 ohms, 300 watts/4 ohms. It is quite suitable for use on ordinary home theater subwoofers, or in a group 2.1 system. The key to the good effect of the subwoofer lies in the design of the pre-amp filter circuit. This product has been optimized and debugged many times, and the effect is quite good, the low frequency dive is very deep, clean and neat, no headbang, and it feels full of strength. As long as it is paired with the right subwoofer, the effect comes out of the horn.
(2)This product adopts high-power switching power supply to ensure that the output energy is uninterrupted, and there will be no soft feet, coupled with high-power output inductance, first-class control, and free retraction. The aluminum plate of the whole machine has a large heat dissipation area, which can ensure the stability of long-term high-power operation.
