Crown’s Three-Year, No-Fault, Fully Transferable Warranty
Crown offers a Three-Year, No-Fault, Fully Transferable Warranty for every new Crown ampli-
fi er—an unsurpassed industry standard. With this unprecedented No-Fault protection, your new
Crown amplifi er is warranted to meet or exceed original specifi cations for the fi rst three years of
ownership. During this time, if your amplifi er fails, or does not perform to original specifi cations,
it will be repaired or replaced at our expense. About the only things not covered by this warranty
are those losses normally covered by insurance and those caused by intentional abuse. And the
coverage is transferable, should you sell your amplifi er.
See your authorized Crown dealer for full warranty disclosure and details. For customers outside
of the USA, please contact your authorized Crown distributor for warranty information or call
574-294-8200.
