Short Circuit Protection
The circuit protects the amplifier from damage due to a short found in the speakers or wiring.
If one of the speakers or its wiring comes in contact with ground, the amplifier will shut down.
To resume normal operation, correct the problem and turn the head unit off, then back on. The
amplifier will reset and play again.

Thermal Protection
To protect the amplifier circuitry against damage caused by prolonged exposure to high
temperatures, a thermal protection circuit is activated if the amplifier reaches excessively
high operating temperature. Once the thermal circuit is activated, the amplifier will shut
down to cool off. The Amplifier will automatically turn back on once it cools down to a safe
operating temperature.

Protection Indicator
This red diagnostic LED on the side panel indicates that the amplifier has gone into protection.
Once on, the amplifier will have no output. To resume normal operation, turn head unit off and
back on again. If the amplifier immediately goes back into protection, check for high
temperature, short circuits or low impedance.
