AMPLIFIER PROTECTION
PC-1400
Both excessive temperature and low impedance (or short circuit) conditions will activate the amplifier's
PC-1800
Both excessive temperature and low impedance (or short circuit) conditions will activate the amplifier's
When the amplifier cools down, or the impedance is corrected, both protection circuits will restore full power. If your amp is turning off/down check your speakers and wiring for low impedance and short circuits. Also, ensure that there is nothing blocking the normal convective airflow of the amplifier. No obstruction should be within 2" of the amplifier on all sides.
NOTE: Low battery voltage will cause the amplifier to run warmer.
