IWISTAO TPA3116 Class D Digital Power Amplifier for Subwoofer 100W DC18V to DC24V Black
Model No: WHFPA-SWTPA3116
This is a dedicated power amplifier designed for subwoofers. Using the original Class D digital power amplifier IC TPA3116, its output power can is up to 100W, and its signal input includes full-frequency signal and low-frequency signal (only one of the two can be selected)
The amplifier does not include a power adapter.
1. Using original TPA3116.
2. The main circuit of the electrolytic capacitor signal adopts a chip electrolytic capacitor with a capacity of 4×470UF, which ensures a strong and continuous power support.
3. The resistors use high-precision chip resistors to ensure a good signal-to-noise ratio of the whole machine.
4. The PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents. Top-notch PCB quality.
