DC 5V Bluetooth/Audio Receiver Digital Amplifier Board

Product description
This is an audio power amplifier board that strengthens low-power, inaudible electronic audio signals such as the signal from radio receiver or electric guitar pickup to a level that is strong enough for driving loudspeakers or headphones. Power amplifiers make the signal audible to listeners. It is the final electronic stage in a typical audio playback chain before the signal is sent to the loudspeakers and speaker enclosures.

Features:
Digital amplifier has a HIGHER OVERLOAD CAPACITY than analog amplifier, and it won't cause crossover distortion, transient inter modulation distortion and you don't have to worry about the loudspeaker internal resistance.
SUPPORT: It supports Bluetooth audio input and DC 5V voltage input by Micro USB.
Dual channel of 3W+3W power output and 2.54mm, 4pin output connector.
Sound quality is very good by using this audio power amplifier module.
Applicable speaker impedance are 4~8ohm, great for turning normal speaker into Bluetooth speaker.
