1 Basic Parameters: The rated power supply voltage of the power amplifier board is 70V of dual power supply, and the voltage can work normally between 55 to 80V (excluding overvoltage burnout!) 2 Power Supply: The power supply is recommended to be a power supply with a good filter of 70V DC dual power supply. Speakers are recommended to use 10-18 inches 4 ohms-8 ohm speakers. 3 Short Circuit Protection: Although the sound output has short circuit protection, try not to short circuit it. Do not connect the positive and negative poles of the power supply wrongly to avoid burning the board. 4 50X Magnification: The voltage magnification of this board is fixed at 50X. If the output power is not enough, the pre amplification will be added according to the specific situation. 5 Note: Please check carefully before turning on the power to ensure that the wiring is correct before turning on the power.
