PROTECTION CIRCUIT
The POWER-LED (Fig. 1,3) lits up, if the amplifier is in operation.
The PROTECT-LED (Fig. 1, 14) 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 events, the internal built-in
protection circuit shuts down the amplifier automatically. The amplifier should work again properly after
you have solved the problems.
