Key benefits Uses the TPA3116 audio amplifier IC for reliable, efficient amplification with clear sound. Low noise performance achieved by carefully selected grade resistors, contributing to a favorable signaltonoise ratio across the system. Robust build and reliable current flow thanks to a 1.6 mm thick doublesided sheet metal PCB with 2 oz copper and a tin spraying finish. Strong and continuous power delivery provided by four 470 uF SMD electrolytic capacitors in the main circuit. Firstclass PCB quality emphasizes durability and longterm stability in everyday use.
