TPA3255 Subwoofer Active Amplifier Board — Digital Home Audio & 2.1 Power Amp

Extensively refined and debugged, this active subwoofer amplifier board produces deep, clean low-frequency performance without harsh thumps, providing a full, powerful feel when matched with the right subwoofer. Powered by the TPA3255 digital power amplifier chip, it delivers output ratings of 600 /2 ohms, 300 /4 ohMs. The board includes a phase-inverted subwoofer switch and a closed-subwoofer switch so each enclosure type can be tuned for best results. A high-power switching power supply ensures continuous, non-sagging output energy, while high-power output inductance and robust output stages give superior control and quick bass rebound. Built with solid materials and an aluminum rear panel, heat is conducted through a large aluminum plate for wide-area dissipation; the result is minimal background noise and stable long-term high-power operation. Ideal for conventional home theater subwoofers or use in a Group 2.1 system.
