Caution:
*Rated for dual power supply voltage: ± 65V, the voltage at ± 58 --- ± 70V can work properly, the positive and negative power supply so as not to burn the board not to pick the wrong.
*The power supply is recommended for ± 65V DC dual power supply filtering good
*The speaker recommended 10-18 inch 4 ohm speaker -8 Europe.
*Although the audio output short circuit protection, but try not to short circuit
*Carefully check before electricity, ensure the wiring is correct before after power.
*The plate voltage is fixed at 40 times magnification, if the output power is not enough, as the case may add its own preamp.
