KNACRO TPA3116 2-0 Dual Channel Stereo HiFi High Power Digital Amplifier Board

Board size: 90 * 84 * 26mm (L * W * H) (not including the potentiometer protruding part of 15mm, the audio input plug inserted DC 4mm; Operating voltage range: DC 12-25V (current 3A or more, if the power of the larger recommended 19-24V / 4A above); Source input sensitivity: 600mV; ?Frequency response: 20Hz - 20KHz; Speaker impedance: two-channel speaker: 3.5-8?; associated mono speaker impedance: 2-4?, Maximum output power: two-channel 50W / 4? + 50W / 4?, associated mono 100W / 2-3?, Two-channel output power: 12V / 10 + 10W (8?) / 15 + 15W (4?); 15V / 13 + 13W (8?) / 25 + 25W (4?); 19V / 22 + 22W (8?) /> 39 + 39W (4?); 22-24V / 32 + 32W (8?) / 50 + 50W (4?); Associated mono output power: 12V / 18W (4?) / 22W (3?) /30W (2?) 15V / 27W (4?) / 35W (3?) / 48W (2?) 19V / 45W (4?) / 55W (3?) / 75W (2?) 24V /70W (4?) / 95W (2-3?) Note: The output power is related to the power supply voltage, the speaker impedance and the source input. Usually higher power supply voltage, can support the output power will be larger. Different impedance horn, can support the output power is also different.
