Product name : HIFI level with filter 2x50W Bluetooth digital power amplifier board
Product model : ZK-502C
Chip solution : TPA3116D2 (with AM interference suppression function)
With or without filter : Yes (the sound is more round and clear after filtering)
Adapted power supply voltage : 5~27V (optional 9V/12V/15V18V/24V and other adapters, high power recommended high voltage)
Adapted speakers : 30W~200W, 492, 802
Number of channels : left and right dual channels (stereo)
Bluetooth version : 5.0
Bluetooth transmission distance : 15 meters (unobstructed)
Protection mechanism : overvoltage, undervoltage, overheating, DC detection, short circuit protection
Tip : Only when the audio input is enough and the power supply voltage/current is enough, there will be enough output power. Power supply voltage is higher
The relative power will be larger, and speakers with different impedances will have different output powers. In the case of sufficient voltage and current, the horn
The greater the relative sound power, the smaller, please pay attention!
