It is specifically designed for professional audio applications and fields that require low noise, low distortion, and high linearity non-staining performance. The noise is below 500nv/rms 20KHz, and the maximum output current can reach 80mA. The current structure adopts multiple pairs of HIFI low-noise transistors and low error surface mount transistors, paired with multiple precision transistors. The overall sound quality is wide and full, with a grand scene and distinct layers. The mid frequency brightness is clear, the density is high, and the low frequency is deep and elastic. High performance temperature stable power supply independent current source is used, which allows bias to remain locked at the optimal operating point regardless of power supply voltage or temperature.
