Power - LED - If the green LED is illuminated, the amplifier is in operation mode.
Protect - LED - If the red LED is illuminated: Overheated, speaker wires shorted, Overload (too low Impedance, less Power Supply), Amplifier
is damaged. The built-in electronic diagnostic protection saves the amplifier and speakers from serious damage. If the red LED lights up due to
overheating, let the amplifier cool down a while and then turn it on again. If the red light is still lighting up, ensure that all connections, especially
the speakers are correct and not shorted. If the amp is still in protection mode, try to restart the amplifier without any speaker or RCA wires. If
the green light is now lighting up, re-check again all speaker- and RCA-connections, to ensure correct connection.
