Product parameters:
Product name: 300W dual channel/600W mono pure rear stage power amplifier board
Power amplifier chip: original TPA3255
Product model: ZK-3002
Adapted power supply: Working voltage range 18-50VDC, limit 53V. It is recommended to use a DC power supply with a voltage of 36-48V and a current of 10A or more. The higher the voltage, the greater the output power.
Adapted speaker: 3-8 ohms, 50-300W in BTL dual channel mode; 2-8 ohms, 100-600W in PBTL mono mode
Heat dissipation method: temperature controlled automatic air cooling, or manually selecting the fan to keep running.
Gain selection: Potentiometer 10 gear adjustment, 26dB-36dB
Bridging method: First cut off the power, turn the No.1 dial switch to the ON position, and short connect the output end R+L+to parallel output, while short connect the R-L to parallel output.
Maximum power:
In BTL mode, 2* 300W@50V 4 Ω, 160W@50V 8 Ω;
In PBTL mode, 600W@50V 2 Ω, 300W@50V 4 Ω, 160W@50V 8 Ω
Protection mechanism: Input undervoltage, overheating, overcurrent, short circuit protection. No input anti reverse protection, positive and negative poles cannot be reversed!
