Caution:
1. The power supply voltage limit of 24V, do not exceed! Otherwise easily capacitance explosive slurry, rectified AC voltage spikes do not exceed 25V. Do not exceed the power supply voltage, positive and negative do not reversed.
2. Recommended power supply is 22V / 5A more filtering better power supply, the lower the voltage, power smaller.
3. The speaker recommended 40-80W speakers.
4. Do not short circuit the audio output is shorted to ground or to each other.
5. Please carefully check before electricity, ensure the wiring is correct after only pass.
