Tl digital high power amplifier chip TPA3255 has lower distortion, high efficiencyand low energy consumption;

The electronic volume control chip BD37524FS-E of Japan ROHM Company isused, which has accurate volume control and ultra-low distortion.

Different frequency points can be set in the high, medium and low frequencybands, and with different gains and different Q values, the frequency responsecurve of the output of the power amplifier can be adjusted conveniently andaccurately, so as to meet the needs of different speakers and different listeningenvironments as much as possible.

The output volume of the subwoofer is adjustable, four low-pass cutoff frequenciesare selected, and the selection of phase 0 and 180 makes the main speaker in the2.1 speaker system better match with the active subwoofer.
