2X TPA3255 4-Channel Digital Class D Power Amplifier Board 315W Mini AMP for Home Theater DIY Speakers

Two compact 4-channel amplifiers built around the original TPA3255 chip, designed for DIY audio and home theater use. High-quality power filtering is provided by four electrolytic capacitors (470UF / 50V x 4) to deliver a stable, continuous power source. Audio performance is improved with dedicated inductors optimized for sound, producing clear and punchy output. Precision chip resistors are used throughout to maintain a favorable signal-to-noise ratio. The PCB is a first-class 1.6mm thick double-sided board with 2.0 ounce copper and a full tin-spraying finish, ensuring reliable conduction for both small and large currents.
