Safety Features
High Frequency: Monitoring and limiting of
continuous input power via MOSFET-based
electronic circuit
Low Frequency: Monitoring of amplifier signal
delivered to woofer via current breaker
switch. Overpowering of the woofer opens
the circuit and requires resetting by
manually pressing the circuit breaker
button.
