Protection Circuitry
The subwoofer is equipped with protection circuitry to provide maximum performance and reliability. The
subwoofer is protected against:
• Overdriving the speaker
• Overdriving the amplifier
• Overheating the amplifier
• Excessive drop in power line voltage
If the protection circuitry is active, the unit may cycle on and off until operating parameters return to normal. Under
more serious conditions, the unit may shut off completely. Normal operation should return upon cooling, but you
may need to turn the power off and then on again to reset the unit.
The overdrive protection circuitry operates constantly without being audible under most situations.
If the subwoofer shuts down, reduce the volume setting and turn the subwoofer off until it cools down. The time
the subwoofer takes to cool down depends on the ambient room temperature, but typically it takes at least 10
minutes for the subwoofer to cool down and recover from a thermal shutdown.
Also, plug the unit into a different wall socket. Overloaded sockets or damaged home wiring circuits can cause
power voltage drops while the subwoofer is drawing high power levels. This condition can result in the subwoofer
shutting down intermittently.
