Based on our measurements, when powered by a 48V/10A power supply, there is no significant increase in power compared to using a 48V/5A power supply. This is because the power has essentially reached the maximum supported by the TI TPA3255 amplifier chip with a 48V voltage input. Increasing the current further does not directly enhance the power output. However, using a 48V/10A power supply compared to a 48V/5A power supply can provide a higher current capacity and greater safety margin for the amplifier. This increased current capacity effectively reduces voltage drops in power lines and internal circuits under high loads, improving the response of the amplifier when handling dynamically complex audio signals. Moreover, the higher current output means that the system is less likely to overheat or shut down due to current overload when facing peak loads, thereby enhancing the overall reliability and stability of the system. Additionally, opting for a more robust power supply can alleviate the operational stress on various components of the amplifier, prolong the lifespan of the equipment, and offer more flexibility for potential system upgrades in the future.
