Maintain ultra low distortion for perfect sound quality. 2Versatile: Class D amplifiers feature for SAGAMI 7W14A inductors for clear and powerful sound, advanced integrated feedback design and proprietary high speed gate driver error correction (PurePath Ultra HD). 3Advertisement Mode: When total harmonic distortion is 10%, the sound amplifier board can drive up to 2 315W/4R loads and 2 150W (no clamp power)/8R loads, and has a 2 VRMS analog input interface that supports high performance DACs (eg, TI's PCM5242) seamless connection. 4High Power and Ultra Low Loss: Achieved by 85mR MOSFET and optimized gate driver scheme. This solution can significantly reduce idle losses (less than 2.5W) compared to traditional discrete implementations. 5Filter Capacitor: The main filter electrolytic capacitor adopts for Nixicon capacity 2200UF/63Vx2, 6 for Nixicon FW series 10UF golden sound input coupling capacitor. Other filter capacitors use the for Nichicon series. PackageList: 1 x_x000D__x000D_PowerAmplifierBoard
