Quick tips:

1. Please plug the power cord into the amp THEN the wall.

Some customers may see some slight sparks flying when they plug the power supply into the amplifier, because they use it in wrong way, you need to connect the amp to the power supply first, then plug the power supply into the 110v AC outlet, don't worry about the sparks, because this is class d amplifier, the capacitors need to charge when the power in, it's normal and safe.

2. The amp will off when you switch off, but it's normal that the power LED light stay on even switch off, the power LED light on means the power supply in.
