4X MAX HiFi Upgraded TPA3255 600W (300W x2) Stereo Low-Noise HIFI Digital Amplifier Board

This amplifier employs an advanced integrated feedback topology together with the proprietary high-speed gate-driver error-correction function (PurePath)™ Ultra high definition, delivering ultra-low distortion across the full audio frequency range. In AD mode the board can drive up to 2 × 315W/4R loads and 2 × 150W (unshipped power)/8R loads at a of 1.5%. It offers a 2 VRMS analog input interface for seamless connection to high-performance DACs such as TI's PCM5242. Beyond sound quality, the TPA3255 design emphasizes high power efficiency and extremely low idle loss (less than 2.5W). This is achieved using an 85mR MOSFET and an optimized gate driver scheme that significantly reduces idle loss compared with traditional discrete implementations. Under the same power supply the output power can be increased by more than 50%. Because materials may not be available at times, substitutions or changes may occur before finalizing performance; it is recommended to switch to a different before ensuring performance. Each upgrade may result in some changes. The 52V is working perfectly. Materials used have also become more expensive, and the board can perfectly drive 4-8 Euro speakers! TPA3255 is a high-performance Class D power amplifier chip with Class D efficiency, capable of delivering true high-end sound-quality circuitry.
