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.
