BEFORE THIS AMPLIFIER IS PLUGGED IN, make sure its rated voltage corresponds to the voltage of the AC power
source to be employed. Failure to use the correct voltage could cause damage to the amplifier when the AC power cable
is plugged in. Do not exceed the rated voltage by more than 10%; operation below 90% will degrade performance or
cause the unit to shut off.
WHEN SERVICING THIS AMPLIFIER:
1. Do not touch the metal frame of the woofer (if removed from the cabinet) when driving the amplifier at high power
levels. In the unlikely event that the output devices in the amplifier fail and present an open circuit during their operation,
AND the driver voice coil was to come in contact with the motor assembly, hazardous voltage could be present at the
woofer frame.
2. When 120/230v-based test equipment is connected to the amplifier in any way, use of a 1000W isolation transformer
(Stancor model GIS-1000 or similar) on the subwoofer is necessary for safety; in addition, an isolator plug, (a
three-to-one pin adapter sometimes called a "cheater plug") should be used on the power cord plug of the test equipment
being used.
