Note:
1. Standard voltage:
±46---±75V can work normally
.
2. The power supply is recommended to use a dual-supply power supply with a good power filter.
3. Before using electricity, please check carefully whether the wiring is correct and firm.
4. Speaker recommended: 10-20 inch 2 ohm ~ 8 ohm speakers.
5. This board amplifier output voltage amplification is 33 times, if the output power is not enough, you need to add a preamplifier.
6. The lower the supply voltage, the greater the load resistance and the lower the total power. The bigger the other way around.
