NONDK TPA3255 Digital Amplifier Board 600W High-Power 300W + 300W Dual-Channel Stereo Low Noise HIFI Audio Amplifier Board

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%. 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. 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 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).
