describe:
According to the power formula p=u x u/r=voltage x voltage/load, power is determined by voltage and load. The higher the voltage, the smaller the load and the greater the power. The voltage range of the board refers to the voltage within this range. The board works fine. Not all voltages and load powers are standard high power outputs. For example, 12V power supply 4 ohms load, 15W high power, 7.5W high power 8 ohms; 24V power supply 4Ω, power 50W, 8Ω 25W; at any time, the power of the power supply must be greater than the power of the power amplifier, otherwise the high volume will not move, and the power will Lowered and cut off, the corresponding power output cannot be achieved.

Precautions for use:
1. The rated power supply voltage is dual power supply & 65V, the voltage is &;58---&70V can work normally (if it exceeds 70V, it will burn, if it burns out, it will not be covered!), If it is Huanniu, the voltage will fluctuate with the grid, because it does not have a voltage stabilizing function. Please use "Yes" to leave blank. Do not connect the positive and negative poles of the power supply by mistake, so as not to burn the circuit board
2. It is recommended to use DC dual power supply; 65V power supply, well filtered
3. It is recommended to use a 10-18 inch 4Ω-8Ω speaker as the speaker
4. Although the audio output has short circuit protection, try not to short circuit
5. Please check carefully before energizing to ensure that the wiring is correct before energizing.
7. The voltage amplification factor of the board is fixed at 40 times. If the output power is not enough, increase the previous level of amplification according to the specific situation.
