Package included：
1000W mono amplifier board x1 if build stereo amp，need 2pcs ！ Rcommend power supply：https://www.ebay.com/itm/353563389877 pls choose 75V version
Precautions for use:
1. The rated power supply voltage is dual power supply ±75V, and the voltage can work normally at ±58---±85V (if it is a power frequency transformer, please leave a margin for voltage fluctuations. The power supply is 3 power supply lines, and the power supply is positive and negative. Don't make the wrong connection so as not to burn the board 2. The power supply is recommended to be a DC dual power supply ±75V power supply with better filtering. 3. The speaker is recommended to use a 10-25 inch 2 ohm -8 ohm speaker 4. Although the audio output has short-circuit protection, try not to short-circuit it 5. Please check carefully before powering on to ensure that the wiring is correct before powering on. 7. The voltage magnification of this board is fixed at 40 times. If the output power is not enough, the pre-amplification may be added according to the specific situation.
