Audio amplifier based on the TPA3255 system with a power of 600 W with an active filter. The input signal is connected via RCA sockets, and the speakers via screw connections. The potentiometer allows you to smoothly adjust the gain with a cutoff frequency of 95 Hz. Thanks to the filter used, only the low tones (bass) are amplified, which is why the module is dedicated to bass speakers (subwoofer). It is powered with the voltage in the range from 30 V to 48 V. It works well in home and professional audio systems.
