IMPORTANT SAFEGUARDS AND
PRECAUTIONS:
All Ampeg products are designed for continuous
safe operation, as long as common sense is used
and steps are taken to help avoid certain problems.
Abiding by the following rules can help prevent
damage to your amplifier, yourself and others.
• The amplifier is equipped with a three-pronged
AC power cord. To reduce the risk of electrical
shock, NEVER remove or otherwise attempt to
defeat the ground pin of the power cord.
• Connect the amplifier ONLY to a properly ground-
ed AC outlet of the proper voltage for your amp.
• Avoid sudden temperature extremes, rain and
moisture. Also, avoid sudden and intense impact.
(If the unit has been subjected to any of the pre-
ceeding abuses, have it looked at by an autho-
rized service center.)
• NEVER set the amplifier on a support that might
give out under its weight.
• Always keep the total speaker impedance at or
above the rated load.
• Unplug the amplifier before cleaning it. NEVER
spray liquid cleaners onto the amplifier. Wipe it
with a slightly dampened, lint-free cloth to remove
dirt and film.
• Don’t use the amplifier if it has sustained damage
to the chassis, controls, or power cord. Refer the
unit to an authorized service center for inspection.
• Amplifiers capable of producing high volume lev-
els are also capable of inflicting permanent hear-
ing loss or damage, if the exposure to such levels
is prolonged. Such damage is progressive and
irreversible!
