Newly
designed active subwoofer power amplifier board, real material,
excellent effect. The power amplifier part uses the TPA3255 digital
power amplifier chip, and the peak power is as high as 600 watts/2 ohms,
300 watts/4 ohMs. Suitable for use on a regular home theater subwoofer,
or a Group 2.1 system. The key to the effect of subwoofer is the design
of the pre-filter circuit.
This
product has been optimized and debugged for many times, and the effect
is quite excellent, low frequency diving is very deep, clean and neat,
will not bang the head, and feel full of strength. As long as it is
matched with the right subwoofer speaker, the effect is quite
comfortable.
This product uses
high-power switching power supply to ensure that the output energy is
continuous, not soft feet, coupled with high-power output inductance,
first-class control force, retracting freely. The whole machine heat
conduction this aluminum plate, the heat dissipation area is large, can
ensure the stability of long-term high-power operation.
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 bottom noise. It is a rare subwoofer
power amplifier board for home theaters.
