Protection Circuit - Autotek TransAm TA1400 Manual De Uso

PROTECTION CIRCUIT

The Operation-LED (POWER, fig. 1,1) lits up, if the amplifier is in operation.
The protection LED (PROTECT, fig. 1,1) 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 protec-
tion circuit shuts down the amplifier automatically. The amplifier should work again properly after you have
solved the problems.
