Protection Circuit - Hifonics Nemesis NXi4404 User Manual

PROTECTION CIRCUIT

The LED (POWER, Fig. 1, 2) lits up, if the amplifier is in operation.
The LED (PROTECT, Fig. 1, 2) lits up, when the amplifier is overheated, or a short circuit occurs resp.
a too low impedance load is connected to the speaker outputs. If this happens, the internal built-in
protection circuit shuts down the amplifier automatically. The amplifier should work again properly after
you have solved the problems.
