Protection Circuit - Crunch groundpounder GPX2000.1D User Manual

PROTECTION CIRCUIT

This LED (Fig. 1, 1) lits up in green, if the amplifier is in operation. If this LED lits up in red, 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.
