Notes:

• The rated power supply voltage is ±70V of a dual power supply, and the voltage can work normally from ±55 to ±80V. If it is a toroidal transformer, since it does not have the function of voltage regulation, the voltage will fluctuate with the power grid

• 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

• a The board needs dual DThe singler supply. Single power supply does not work! The power supply voltage is ±55V to ±80V, if it is too low, it will not work, and if it is too high, it is easy to burn the board

• 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
