Crown’s Three-Year, No-Fault, Fully Transferable Warranty
Crown offers a Three-Year, No-Fault, Fully Transferable Warranty for every new Crown ampli-
fier—an unsurpassed industry standard. With this unprecedented No-Fault protection, your
new Crown amplifier is warranted to meet or exceed original specifications for the first three
years of ownership. During this time, if your amplifier fails, or does not perform to original
specifications, 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 amplifier.
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.
