and possible damage. 70% of the maximum amplifier
output is normally available when the volume control is
set to its center position.

In cases where the signals described below are applied

to the speakers, even it the signals are below the

maximum allowable input, they may cause an overload
and burn the wiring of the speakers. Be sure to lower
