Description:

This is an audio power amplifier that amplifies inaudible low-power 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. It is the final electronic stage in a typical audio playback chain before sending the signal to the speakers and sound boxes.

Functions:

The digital amplifier has a higher overload capacity than the analog amplifier and does not cause crossover distortion, intermodulation-transient distortion, and you don't have to worry about the internal resistance of the speaker. Supports Bluetooth audio input and 3.5mm audio jack aux input. Dual channel output power of 30W + 30W and wide input voltage range from 8V to 26V DC. The sound quality is very good when using this audio power amplifier module.

The applicable speaker impedance is 4.6.8 ohms, ideal for converting a normal speaker into a Bluetooth speaker. Automatically enter Bluetooth pairing mode when the device is turned on, the device name is "Xpecial Audio".
