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 prob-
lems. Abiding by the following rules can help prevent damage to your amplifier, yourself and others.
• The amplifier is equipped with a three-prong 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 grounded AC outlet of the proper voltage for your amp. If no grounded outlet is available, use only
an approved method of adapting to a two-prong AC source.
• Avoid sudden temperature extremes, rain and moisture. Also, avoid sudden and intense impact. (If the unit has been subjected to any of the
preceding abuses, have it looked at by an authorized service center.)
• NEVER set the amplifier on a support that might give out under its weight.
• Always keep the total impedance at or above the rated load.
• Unplug the amplifier before cleaning it. NEVER spray liquid cleaners onto the unit. Wipe the unit 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 levels are also capable of inflicting permanent hearing loss or damage, if the exposure to such
levels is prolonged. Such damage is progressive and irreversible! Caution is advised and ear protection recommended when playing at
extremely loud levels.
The chart below shows the U.S. Government Occupational Safety and Health Administration (OSHA) regulations which were in effect at the time of
this publication for permissible noise exposure, per 29CRF1910, Table G-16.
According to OSHA, any exposure in excess of those listed above could result in some hearing loss.

THIS EQUIPMENT HAS BEEN DESIGNED AND ENGINEERED TO PROVIDE SAFE AND RELIABLE OPERATION. IN ORDER TO PROLONG THE
LIFE OF THE UNIT AND PREVENT ACCIDENTAL DAMAGES OR INJURY, PLEASE FOLLOW THESE PRECAUTIONARY GUIDELINES:
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT OPEN CHASSIS; DO NOT DEFEAT OR REMOVE THE GROUND PIN OF THE
POWER CORD; CONNECT ONLY TO A PROPERLY GROUNDED AC POWER OUTLET.
WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS EQUIPMENT TO RAIN OR MOISTURE.
CAUTION: NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
CAUTION: OUR AMPLIFIERS ARE CAPABLE OF PRODUCING HIGH SOUND PRESSURE LEVELS. CONTINUED EXPOSURE TO HIGH SOUND
PRESSURE LEVELS CAN CAUSE PERMANENT HEARING IMPAIRMENT OR LOSS. USER CAUTION IS ADVISED AND EAR PROTECTION IS REC-
OMMENDED IF UNIT IS OPERATED AT HIGH VOLUME.
