An Introduction to your new AmpegSVT-150H Bass Amplifier
First of all, thank you for making what could be one of
the best choices you could ever make concerning your
musical career - choosing one of the finest bass amplifiers
available, an Ampeg SVT-150H.
Your new bass amplifier offers you many outstanding
features, such as 150 watts of pure bass energy, total tone
control and rugged construction which make it a true per-
former’s bass amp.
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, NEVERremove or otherwise
attempt to defeat the ground pin of the power cord.
Connect the amplifier ONLYto a properly grounded 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 preceeding 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 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 cen-
ter 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!
