BRZHIFI PA-402 Thick-film STK402-240 Bluetooth5.3 High Performance Power Amplifier Desktop Audio Amplifier
Description:
- STK402-240 is a high-end audio power amplifier chip for Sanyo, with its core advantages being ultra-low distortion of 0.01% and superior performance. From the parameters, it has been measured to have a thrust equivalent to Class D 100W with an output power of 25W/8Ω, benchmarking against thousand yuan grade finished power amplifiers. It features a sound style that combines the taste of a gallbladder machine and Class A control power, with a rich and full mid frequency, delicate vocal reproduction, and a warm texture of a gallbladder machine. The high-frequency extension is smooth and not harsh, and the low-frequency diving has elasticity. Its dynamic performance is better than traditional Class A and B power amplifiers, and it is suitable for driving 3-5 inch bookshelf boxes or monitoring speakers.
