Protection Circuit - Crunch GROUND POWER GPX1000.1D Manual De Uso

PROTECTION CIRCUIT

The POWER/PROTECTION LED (Fig. 1,9) lights up green, if the amplifier is in operation.
The POWER/PROTECTION LED (Fig. 1,9) lights up red, when the amplifier is overheated, or a short circuit
occurs resp. a too low impedance load is connected to the speaker outputs. If this events, the internal built-in
protection circuit shuts down the amplifier automatically. The amplifier should work again properly after you
have solved the problems.
