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: Specifications: Audio Input: Bluetooth Output Power: 2x30W Suitable Speaker Impedance: 4ohm, 6ohm, 8ohm Input Voltage: 8V~26V DC Auxiliary Input: 3.5mm jack Size: 71 x 52mm / 2.79 x 2.04" Package Includes: 1 x Amplifier Board
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
It supports Bluetooth audio input and 3.5mm audio jack auxiliary input
Dual channel of 30W+30W power output and a wide input voltage range from 8V to 26V DC
Sound quality is very good by using this audio power amplifier module
Applicable speaker impedance are 4, 6, 8ohm, great for turning normal speaker into Bluetooth speaker
