Fuhjythy HiFi Upgraded MAX Version TPA3255 600W High-Power 300W X 2 Stereo Low Noise HIFI Digital Amplifier Board

The 52V is working perfectly. The materials used have also become more expensive, and it can perfectly drive 4-8 Euro speakers! Under the same power supply, the output power can be increased by more than 50%. TPA3255 is a high-performance Class D power amplifier chip, which has Class D efficiency and can bring true high-end sound quality circuits. This device features advanced integrated feedback design and proprietary high-speed gate driver error correction function (PurePath) Ultra high definition. This technology enables the device to maintain ultra-low distortion throughout the entire audio frequency band while showcasing sound quality. In addition to excellent audio performance, TPA3255 also has two major advantages: high power efficiency and ultra-low power level idle loss (less than 2.5W). This can be achieved through an 85mR MOSFET and an optimized gate driver scheme. This device operates in AD mode and can drive up to 2 315W/4R loads and 2 150W (unshipped power)/8R loads at a of 1.5%. It also has a 2 VRMS analog input interface and supports seamless connection with high-performance DACs (such as TI's PCM5242). This scheme can significantly reduce idle loss compared to traditional discrete implementation schemes.Due to the fact that materials may not be available at times, it is recommended to switch to a different before ensuring performance. Each upgrade may result in some changes
