XH-M568 Digital Power Amplifier Board TPA3116D2 Two-channel 2*100W HIFI Audio Amplification Module The digital power amplifier board adopts the power amplifier chip TPA3116D2, which has high-fidelity stereoscopic sound quality; 3 on-board audio input ports, AUX audio base and 2 3P terminals; (Note: Every time.) Only one input can be used, but 3 input ports can be used for audio switching) The power amplifier input power supply is DC 12~24V, with two-channel output, output impedance is 4~8?, and the maximum power is 100W*2; At the same time, the power amplifier also has two power outputs, DC 5V-0.2A and DC 12V (electricity The flow depends on the input power supply of the amplifier board) on-board volume potentiometer that enables volume adjustment and power amplifier power on and off. Output impedance: 4-8? Output voltage: DC5V/DC12V Output power: 2*100W Chip Model: TPA3116D2 Power efficiency: 90% or more Audio input: AUX ? 3P terminal (2pcs) Product size: 66*58*28mm Number of channels: Binaural Installation size: 60*52mm Supply voltage: DC12-24V Audio input: All 3 audio ports can be used as audio input, but only one end can be used at a time port, 3 audio ports can be used as audio switching applications. Output power supply: The power amplifier board outputs a DC5V-0.2A power supply, which can be used for other 5V equipment power supply, such as control panel, Bluetooth decoding board; It also outputs a phase with the power amplifier's supply voltage The current depends on the power supply of the power amplifier, and it can also be used as a power amplifier
