DC12-24V High Power 2*100W Channel Digital Amplifier Audio Board Stereo Amp

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