Package include:
1 x Digital Amplifier Module
This is a intact board. You are not connected correctly. Please separate them.
Precautions for use:
1. Live wiring is prohibited.
2. The positive and negative poles of the power supply cannot be reversed., Otherwise, it will burn down.
3. Do not use under excessive pressure. Dual DC power supply is required. (Single power supply cannot be used).
4. Power supply voltage ± 45V - ± 70V (too low to work, too high to burn).
The maximum efficiency of the board is 500w. (At ± 65v, 4 ohms, with a load input of 1V effective value)
