Power amplifier board, module, 50W + 50W for speaker

Features:1.The digital amplifier has a higher overload capacity than the analog amplifier, and it will not cause crossover distortion or transient intermodulation distortion, and you don't have to worry about the internal resistance of the speaker.2.It supports Bluetooth V4.0 audio input and DC voltage input from 8V to 25V.3.Uses the NE5532 preamp and the TDA7492 chip for dual-channel 50W + 50W power output.4.The sound quality is very good when using this audio power amplifier module.5.The applicable speaker impedance is 4, 6, or 8 ohms, ideal for converting a standard speaker into a Bluetooth speaker.Specifications:Description: This is an audio power amplifier board that boosts low-power, inaudible electronic audio signals, such as the signal from a radio receiver or an electric guitar pickup, to a level loud enough to drive speakers or headphones.Power amplifiers make the signal audible to listeners.This is the final electronic stage in a typical audio playback chain before the signal is sent to speakers and enclosures.Features: The digital amplifier has a higher overload capacity than the analog amplifier and will not cause crossover.Distortion, transient intermodulation distortion and you don't have to worry about the internal resistance of the speaker.
