PROTECTIVE CIRCUITS
(SWEET 15.3, SWEET 25.2 only)
HF oscillation:
This safety feature prevents from damages caused by frequencies above 20 kHz (feedback, etc.) by
switching the power amp off.
Temperature:
Should the temperature controlled fan cooler prove to be insufficient in extreme conditions, this circuit
protects the output stage transistors from destruction by switching the device off.
Direct current (DC):
This circuit continuously monitors the power amp output for direct current and protects the loud-
speakers from overload in case a transistor burns out.
