The use of precautions:
1. Rated supply voltage for the Dual power ± 65V, Voltage ± 58 --- ± 75V can work (if it is power frequency transformer, the voltage fluctuations left margin, the power supply is 3 power lines, the positive and negative power supply Do not mistake the wrong board to burn out
2. Power supply recommended DC dual power ± 65V filter better power supply
3. Speakers Recommended 10-25 inch 2 -8 OHMspeakers
4. Although audio output short-circuit protection, but try not to short circuit
5. Please check carefully before the power to ensure that the correct wiring can be energized.
7. This board voltage magnification is fixed at 40 times, if the output power is not enough, depending on the circumstances plus its own pre-amplification.
