Product parameters:

Product name: 100W+100W dual channel/200W single channel pure rear stage amplifier board
Power amplifier chip: TPA3221
Product model: ZK-2001
Adapted power supply: The working voltage range is 10-30VDC, with a limit of 31V. It is recommended to use a DC power supply with a voltage of 24-30V and a current of 10A or more. The higher the voltage, the greater the output power. Never connect to AC power, otherwise it will burn out!
Adapted speaker: 3-8 ohms, 20-100W in BTL dual channel mode; 2-8 ohms, 50-200W in PBTL mono mode
Heat dissipation method: Multi tooth heat sink
Gain selection: 2nd DIP switch 2nd gear selection, 28dB, 38dB
Bridging method: Turn off the power first, turn the No.1 dial switch to the ON position, and the output end R+L+is short circuited in parallel for output, while R - L - is short circuited in parallel for output.
Maximum power: In BTL mode,2*70W@24V 4Ω ,2*100W@30V 4Ω ;
               In PBTL mode, 150W@30V 3Ω, 200W@30V 2Ω,110W@30V 4Ω
Protection mechanism: Input under voltage, overheating, overcurrent, short circuit protection.Input anti reverse protection
