Digital TPA3116D2 2.1 HIFI subwoofer amplifier board 50w+50w+100w beyond

DC12-24V TPA3116D2 2.1 Channel Digital Subwoofer Power Amplifier Board defined as the most perfect 2.1 digital amplifier board. This module is said to be the 2014.8.20 latest upgraded version with features beyond LM1875. The module consists of two onboard high-quality TPA3116D2 digital amplifier chips. Thus offers better Sound quality, high efficiency, and amplifying power. The heart of the module is a TPA3116 high-performance power amplifier chip. It operates at a DC single power supply 8-25V wide working voltage.

TPA3116D2 Dual Audio channel amplifier board module is a 12-24V single On-board TPA3116D2 stereo audio amplifier chip. Hence TPA3116 Audio amplifier board module offers very low harmonic distortion and intended to use as a Class D amplifier. Meanwhile, the Onboard chip consists of dual-channel output, with 50W (left channel) + 50W (right channel). And it offers an efficiency of up to 90% or more. This digital power amplifier functions as a standard monaural power amplifier board or a subwoofer power amplifier board, with a pre-amp NE5532 buffer matching.

Thus 50W x 2+100W 2.1 channels (left/right channel and subwoofer channel) ensures high efficiency and low-heat compared to other amplifier boards. They can adjust the volume as per the user’s requirement. TDA7266 audio amplifier module has a wide range of applications in-car stereo receivers, tape recorders, medium-power audio equipment, households, etc. Moreover, the Digital Subwoofer  Board supports a power interface with a standard 5.5mm power jack, as same as most laptop power supplies.
