Upgraded MAX Version TPA3255 600W High-power 300W + 300W Stereo Low Noise HIFI Digital Amplifier With Case

It is now the product of the 2025 model with a new update. The 52V system is also operating normally, and the materials have become even more high-end. It can perfectly drive 4-8 ohm speakers! Under the same power supply, the output power has increased by more than 50%. TPA3255 is a high-performance D-class power amplifier chip. It has D-class efficiency and can bring true high-end audio quality circuits. This device has advanced integrated feedback design and proprietary high-speed gate driver error correction function (PurePath? Ultra HD). This technology enables the device to maintain ultra-low distortion throughout the audio frequency band while presenting audio quality. The device operates in AD mode, and when THD is 1.5%, it can drive up to 2 x 315W/4R loads and 2 x 150W (unclipped power)/8R loads, and it also has a 2VRMS analog input interface, supporting seamless connection with high-performance DACs (such as TI's PCM 5242). In addition to excellent audio performance, TPA3255 also has the advantages of high power efficiency and ultra-low power-level idle loss (less than 2.5W). This can be achieved through 85mRM0SFET and an optimized gate driver solution. This solution can significantly reduce idle loss compared to traditional discrete implementation schemes.
This model is a pure power amplifier without Bluetooth function and without a power supply. It can be configured with an external Bluetooth receiver power supply using a DC power supply ranging from 18V to 52V. Correspondingly, it can be configured with power supplies for 6.5-19-inch speakers. The size of the power supply can be selected based on your actual volume usage. If you want a very loud volume, you can choose a high-voltage and high-current switching power supply, such as 48V 12A, which is quite large. (Note that the switching power supply with constant current and constant voltage cannot be used. You can also use electric vehicle batteries or lithium batteries of 24V, 36V, or 48V for
