System Protection

The Master Reference Subwoofer incorporates a complement of sophisticated

protection circuits to safeguard your system. This circuitry constantly evaluates

the operation of the Master Reference Subwoofer and provides protection

against potentially damaging DC input or output. Regulator operation is also

continuously monitored to ensure constant voltage to the output stage. These

protective systems are designed to prevent damage to the Master Reference

Subwoofer or loudspeakers caused by other defective components, faulty

wiring, system mishandling, or subwoofer failure.

Subwoofer Care

Because the Master Reference Subwoofer is capable of enormous power output,

it important to exercise care during system operation.

Avoid any action that can generate large transient signals. Always mute the

preamplifier output before switching between active sources or cueing a source

component.

Do not change inputs to the subwoofer while the subwoofer is on.

Use care when listening at high volume levels. Always lower the volume level at

the first sound of loudspeaker distress.
