TPA3255 Digital Amplifier Board Stereo 300W x 2, Bridged Mono 600W Amplifier Audio Music Power Amplifier Board
- 300W dual channel / 600W mono pure rear stage power amplifier board. Bridge single circuit 600W, dual circuit 300W+300W. Power amplifier chip: Original TPA3255. Adaptable power supply: Operating voltage range 18-50VDC, limit voltage 53V. A 36-48V DC power supply with a current of 10A or above is suggested. Higher voltage results in greater output power. Speaker compatibility: 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 setting the fan to run continuously. Gain selection: Potentiometer with 10-level adjustment, 26dB-36dB. Bridging method: First disconnect the power, turn the No.1 dial switch to the ON position, and short connect the output terminals R+L+ for parallel output, while short connecting the R-L for parallel output. Maximum power: In BTL mode, 2*300W@50V 4 , 160W@50V 8 ; In PBTL mode, 600W@50V 2 , 300W@50V 4 , 160W@50V 8 . Protection mechanism: Input undervoltage, overheating, overcurrent, and short circuit protection. No input reverse polarity protection. Positive and negative poles must not be reversed!
