DC12 26V High Power 120W+120W Dual channel Stereo Digital Audio Power Amplifier

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: The amplifier chip supports short circuit protection, overheating protection, over voltage protection, under voltage protection and DC fault protection. Large capacity capacitance is soldered with PCB board without possibility of causing a short circuit. 1.6mm thick PCB board is beautifully and well designed, and there is only a small quantity of soldering joints on the back. Comes with a special designed black heat sink which ensures a better heat dissipation. Make sure the positive and negative pole of power supply is connected correctly and do not use small power loudspeaker.
