Assembled YJ TPA3116 4.1 class D Bluetooth Amplifier board 4x50W+100W Module

 100% brand new and high quality

With original TPA3116

Main circuit electrolytic capacitor signal from Taiwan brand, the main chemical used in Japan dedicated filter capacitor capacitance electrolytic 4 × 3300UF, ensure strong support for a steady stream of power.

Resistance selection Rings metal resistance, the main circuit employs a precision of ± 1% chip resistors, ensure the machine a good signal to noise ratio.

 1.6mm thick sheet using double-sided PCB, 2.0 oz copper thickness, HASL whole process to ensure that the size of the current through the good performance. PCB-class quality.

Fully enclosed dust-proof potentiometer, the performance is more stable, more durable than ordinary potentiometer!

Gray with red ring dedicated high-current inductor sound, ensuring crisp and powerful sound.

Switching signal components using good quality Hongfa relays
