AC N and AC L: Power input AC 210-230V. Do not exceed the supply voltage range.2. AC N and AC L: AC power supply input. Can be changed to 110v power supply. After modification, the 220V power supply cannot be used again.3. AC100-115V working status: connect any pin of CP3 to any pin of CP44. AC200-240V: CP3, CP4 OPEN5. P1 +24v and G pins are connected to 24v fan. Pay attention to the polarity of the fan, do not connect it in the opposite direction. The fan interface cannot be short-circuited, otherwise it will cause a fault and the device to not work!6. Because the power of the power amplifier is large, the board needs to be diipated when it is working. When no load, the board also needs to diipate heat. A heat sink needs to be installed for heat diipation. There are many other heating elements, such as nsformers, output inductors, large s, large s, and ballast bridge stacks. These components also require fans to diipate heat. It is recommended that a fan blows air from the amplifier section to the power supply section.7. There are four output ports. Every two terminals are connected in parallel, and any terminal can be connected to speakers. SPK- and SPK+ are load outputs, connect to speakers with a load of 4 s to 8 s. Do not connect speakers with a load of le than 4 s.8. The auxiliary power supply of the P2 socket outputs +15V/-15V at 500MA to the preamp, and cannot be used for overloading. Also, it can not connect to the input voltage. It is only output to the preamplifier board.9. G in of P2 socket is the signal input. Among them, G represents GND, which is also the negative pole of the signal input; in represents the positive pole of the signal input. Please pay attention to the polarity when connecting, do not re the connection. When the maximum input signal is 1.5V, its output power reaches the maximum value, which cannot exceed the input 1.5V, so as not to damage the power amplifier due to overload.10. Input signal cable should preferably be shielded to avoid interference. Do not hot-plug the signal input. It is not recommended to connect to mobile phone signal.11. AC power supply is high voltage and cannot be tied together with the ba wire. AC input is high-voltage power, which cannot be tied together with the signal input, auxiliary power +/-15 output, and speaker output wire.12. Do not tie the signal input with the speaker wire, so as not to cause high-frequency s-excitation and damage the power amplifier.13. The switching power supply is charged with high voltage, so remember not to touch the high voltage part with your hands.14. If D12 lights up red, it means there is a short circuit in the power amplifier part. This could be because of a shorted fan, a shorted preamp, or the broken amplifier.15. If the temperature of the heat sink exceeds 85°C, the power amplifier will automatically turn on the protection function and stop working. After waiting for the temperature to drop, it will start automatically.
