TPA3116 2x50W+100W HiFi Digital Power Amplifier

Features: Transmission distance up to 10M High operating efficiency, up to 90% Using the original TPA3116 NE5532 The main filter capacitor uses a special electrolytic capacitor capacity of 3300UF, the other imported, to ensure a strong stream of dynamic support. Resistance selection of high-precision chip resistors, the main circuit using precision 1% of the five ring metal film resistors to ensure a good signal to noise ratio. PCB using 1.6mm thick double-sided sheet, 1.5 oz copper thickness, spray tin the whole process, to ensure the size of the current through the good performance. First-class PCB quality. Fully enclosed dust-proof potentiometer, more stable performance, more durable than ordinary potentiometers. Red ring with high current inductor, to ensure crisp and powerful sound.
