Note:
1. The rated power supply of the power supply is power supply ± 65V, and the voltage is 45 ‑ ± 70, which can work normally (if it exceeds 70V, it will burn out)
2. The recommended power supply is ± 65V filtered DC power supply.
3. Recommended 10‑18 4‑8 speakers.
4. Although the output is short circuit protected, please try not to short circuit.
5. Please check carefully before power on to ensure that the wiring is correct before power on.
6. The voltage magnification of this board is fixed at 50 times. If the output power is not enough, the front stage amplification can be increased according to the specific situation.
