TPA3116 Subbwoofer Amplifier Board 80Wx2+100W 2.1 Channel Digital Power Amplifier Audio Board NE5532 OP Amp Preamplifier
Product Description
The power amplifier board utilizes two TDA3116D2 chips as its core: one for left and right channel power amplification, one for bridge-connected subwoofer driving, and two NE5532 audiophile amplifiers for current control and low-pass filtering.
A redesigned low-pass filter provides enhanced subwoofer thrust and offers a wide range of adjustment options, including adjustable subwoofer volume and left and right channel volume. This eliminates issues such as no-load heating, power-on/off clatter, floor noise, and low bass.
Using Sakamoto ELNA audio-specific capacitors, ruby capacitors, and high-precision, fully sealed potentiometers, the overall layout is streamlined, resulting in compact size, high efficiency, and high power.
