DC1224V High Power 2*100W Dual Channel Digital Amplifier Audio Board Stereo Amp

About this item

• Description: This is an audio power amplifier board that strengthens lowpower, 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. The amplifier chip supports short circuit protection, overheating protection, over voltage protection, under voltage protection and DC fault protection. 1.6mm thick PCB board is beautifully and well designed, harder and more durable. 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. Specifications: Chip: TPA3116D2 Input Voltage: DC1224V Output Power: 100W*2 Input Impedance: 51K*2 Power Efficiency: >90percent Output Match: 48 Ohm Frequency Response: 14100KHz SNR: 100db Output Channel: Left&right dual channel Size: 105 x 65 x 23mm 4.13 x 2.56 x 0.9 Package Includes: 1 x Power Amplifier Board Note: Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering. .
