Working voltage: DC12V to DC24V (outer diameter 5.5MM inner diameter 2.5 power interface) 7. Maximum output current: 2A 8. Input: Bluetooth 5.0 RCA 9. Output: 2.1 channels (left channel + right channel + subwoofer channel) Maximum output power: left and right channels 50W/4 Ω ,25W 8Ω, subwoofer channel 4 Ω 100W ,8 Ω 50W From right to left is: total volume adjustment, left and right channel ba adjustment, left and right channel treble adjustment, Subwoofer frequency adjustment, subwoofer volume adjustment, Precautions for use: 1 First connect the power adapter and digital power amplifier board through the 5.5MM diameter power port, and then connect the 220V power supply of the power adapter, so as to prevent the boot shock and the power spark. The wrong way is to turn on 220V first, then link the power adapter and digital power amplifier board. 2 The low-power mute switch on the machine, the actual power off is the power adapter outside the machine. So the switch controls the mute instead of the total power control. 3 19V power supply will be much more powerful than 12V power supply, and the dynamics are much better. package: TPA3116 2.1 bluetooth 5.0 High Power amp *1
