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 cross-distortion, transient intermodulation distortion and you do not have to worry about the internal resistance of the speaker. 2. It supports Bluetooth V4.0 audio input and DC 8V to 25V input. 3. It uses the NE5532 preamp and TDA7492 chip for dual-channel 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, and 8 ohms, ideal for converting a standard speaker into a Bluetooth speaker. Specifications: Description: This is an audio power amplifier board that amplifies low-power, inaudible electronic audio signals, such as the signal from a radio receiver or an electric guitar pickup, to a level strong 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 amplifiers. Features: The digital amplifier has a higher overload capacity than the analog amplifier, and it will not cause crossover distortion, transient intermodulation distortion, or interference. You don't have to worry about the speaker's internal resistance. It supports Bluetooth V4.0 audio input and DC voltage input from 8V to 25V. The integrated amplifier uses a NE5532 preamp and a TDA7492 chip for dual-channel 50W output power. The sound quality is very good when using this audio power amplifier module. Applicable speaker impedances are 4, 6, and 8 ohms, ideal for converting a standard speaker into a Bluetooth speaker.
