1.Power amplifier chip: original TPA3255
2.Product Model :ZK-3002
3.Adaptive 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 more than 10A. The higher the voltage, the greater the output power.
4.Adaptive speaker: 3-8 ohms, 50-300W in BTL dual channel mode; PBTL mono mode 2-8 ohms, 100-600W
5.Heat dissipation mode: temperature control automatic air cooling, or manual selection of fan rotation.
6.Gain selection: Potentiometer 10-speed adjustment, 26dB-36dB
7.Bridge mode: Power off first, switch the DIP switch No. 1 to the ON position, output R+ L+ short-circuit parallel output, R-L - short-circuit parallel output.
8.In BTL mode, 2*300W@50V 4Q, 160W@50V 8Q; Under maximum power PBTL mode, 600W@50V 2Q, 300W@50V 4Q; 160W@50V 8Q.;
9.Protection mechanism: input undervoltage, overheat, overcurrent, short circuit protection.
10.No input anti-reverse protection, positive and negative terminals can not be reversed! ;
