Audio 100W Subwoofer Full Frequency Power Amplifier TPA3116 Digital Power Amplifier Class D

Feature The overall size of the power amplifier 68 5X33X90mm excluding knobs and rear terminals Precautions for use The normal operation is to first connect the external power supply and the power connection port of the digital power amplifier and then connect the 220V power cord of the external power supply to the mains socket The wrong approach is to first connect the mains interface of the external power supply and then input the output interface of the external power supply to the digital power amplifier because the digital power amplifier has a filter capacitor so that the capacitor is charged and discharged and a low voltage small spark is generated within 0 1 seconds of contact Although low pressure has no effect it is also a bad habit Package includes 1 x Power Amplifier board
