Important Notes:

• The rated power supply voltage is ±70V of a dual power supply, and the voltage can work normally from ±55 to ±80V.
• 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 to 8 ohms speakers
• Although the audio output has short circuit protection, try not to short circuit
• Please check carefully before turning on the power to ensure that the wiring is correct before turning on the power
• Do not connect the positive and negative poles of the power supply wrongly to avoid burning the board
• The voltage magnification of this board is fixed at 50 times. If the output power is not enough, the pre-amplification can be added according to the specific situation
• The board needs dual power supply. Single power supply does not work!
• The maximum effective power of the board is 500W (in the case of ±75V 4 ohms load input 1V RMS)

Package Includes:

• 1 x Digital Power Amplifier Board
