Note:
1. This is a pure power amplifier board, the sensitivity of the input signal is 1.5V rms, if your input signal voltage cant reach this value, it is recommend to add preamp.
2. Rated supply voltage is 65V, range from 58 to 70V, do not over 70V! Positive & negative should be correct.
3. Recommended power supply is 65V.
4. Recommended 4-8O / 10-18inch speaker.
