Product parameter

• 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!
• Voltage:
• 12V ------ 8 ohm speaker/12W (left channel) + 12W (right channel), 4 ohm speaker/20W+ 20W
• 15V ----- 8 ohms/18+ 18W, 4 ohms/more than 30 + 30W
• 19V ---8 ohms/32 + 32W, 4 ohms/more than 45 + 45W
• 24V ---- 8 ohms/38 + 38W, 4 ohms/more than 55 + 55W
