The speaker has short circuit protection output: yes (automatic reset after short circuit is removed) 28. 28. Start-up delay Anti-shock sound 1-3 seconds Package Included: -1 x Power Amplifier Board Attention: Attention: This power amplifier board is an integrated digital power amplifier board and switching power supply. Tips: 1. AC NE AC L: AC power input 210-230v. Do not exceed the supply voltage range. 2. ac ne ac l: ac power supply input. Can be switched to 110v power supply. After modification, 220v power supply cannot be used again. 3. AC100-115V working status: connect any pin of cp3 to any pin of cp4 4. AC200-240V: cp3, cp4 open 5. pins p1+24v and g are connected to 24v fan. Pay attention to the fan polarity, do not connect it in the opposite direction. The fan interface cannot be short-circuited, otherwise it will cause a failure and the device to not work! 6. Because the power of the power amplifier is large, the board needs to be dissipated when it is working. When no load, the board also needs to dissipate heat. A heat sink needs to be installed for heat dissipation. There are many other heating elements such as transformers, output inductors, large resistors, large capacitors and ballast bridge stacks. These components also require fans to dissipate 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 either terminal can be connected to the speakers. spk-and spk+ are load outputs, connect to speakers with a load of 4 ohms to 8 ohms. Do not connect speakers with a load of less than 4 ohms. 8. The auxiliary power supply from socket P2 outputs + 15v/-15v at 500ma to the preamp, and can not be used to overload. Also, it cannot connect to the input voltage. It’s just output to the preamp board. 9. g inside socket p2 is the signal input. Among them, g represents gnd, which is also the negative pole of the signal input; em represents the positive pole of the signal input. Please pay attention to the polarity when connecting, do not reverse 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. The input signal cable should preferably be shielded to avoid interference. Do not hot-plug the signal input. It is not recommended to connect to cell phone signal. 11. 11. The AC power supply is high voltage and cannot be tied together with the low wire. AC input is high voltage power, which cannot be tied together with signal input, auxiliary power +/-15 output, and speaker output wire. 12. 12. Do not tie the signal input with the speaker wire, so as not to cause high frequency self-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 that there is a short circuit in the power amplifier part. This could be because of a short fan, a short preamp, or a broken amplifier. 15. 15. If the heat sink temperature 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.
