LM3886 Fully Balanced Power Amplifier Board Kit120W+120W HiFi Stereo 2-channel

Description

Product Details:
① This is a two-channel, one-board one channel. This is the price of two boards kit.
② Each channel uses two Texas Instruments original LM3886FT amplifier chip.
③ The signal path resistance adopts the ring resistor of ± 1% of 718 military regulation precision. The high-power resistance adopts Fukushima of Japan or Japan light tone, which ensures the good signal-to-noise ratio of the whole machine.
④ Main filtering Using two NOVER 10000UF / 50V HiFi capacitance.
⑤ UPC1237 + Omron relay speaker protection circuit.
⑥ The pure dc structure is adopted.
⑦ Fully balanced structure.
⑧ Two channels separate system board, and separate power supply, the volume potentiometer point chassis through the ground, the real realization of dual mono, two channels do not affect each other, to eliminate mutual crosstalk, so absolutely discrete.
Specifications:
