SERIAL NUMBER

DATE OF PURCHASE

Diamond Audio Technology, Inc. (DAT) warrants this amplifier to be free from defects in material and workmanship for the lifetime of the 

amplifier  in  its  original  installation  provided  the  amplifier  was  purchased  from  and  installed  by  an  authorized  DAT  retailer.    Amplifiers 

purchased from but not installed by an authorized DAT retailer carry a one (1) year parts and labor guarantee.  

This warranty is not transferable and applies only to the original purchaser of this amplifier in its original installation. 

 Original 

purchaser  must  reside  in  the  United  States  and  register  the  amplifier  with  DAT  within  30  days  of  installation.    Warranty  registration 

information  can  be  found  at  www.diamondaudio.com  or  by  calling  866-328-2834.    Original  purchaser  must  be  able  to  provide  proof  of 

purchase and installation with the sales receipt from the authorized DAT retailer that sold and installed the amp.

Should a manufacturing defect occur in the first three (3) years of the above said warranty period, DAT will replace the defective product 

with  new  product  of  the  same  or  equivalent  value  and  performance.    Should  the  defect  occur  after  the  first  three  (3),  DAT  will  (at  its 

discretion), repair or replace the defective product or parts with new or remanufactured product for as long as the amplifier is in its original 

installation.  Damage or failure caused by any of the following is not covered under this warranty policy:  negligence, improper use, abuse, 

product modification, unauthorized repair attempts, accident, acts of God, misrepresentations by DAT retailers, and improper/inadequate 

packaging during return shipping.

Warranty is void if serial numbers have been removed, altered or defaced or if protective seal is broken.

In the event a DAT product should require service, you should visit the authorized DAT retailer you purchased the product from and they 

can expedite your claim.  All claims must fall into the guidelines listed above and be accompanied by a copy of the original sales and 

installation receipt from that authorized DAT retailer.

Product returned for warranty service must be freight-prepaid, properly packaged and clearly marked with the Return Authorization (RA) 

number issued by DAT.  Any product returned to DAT that is improperly packaged, does not have a RA number clearly marked on the package, 

or never received a RA number; may be refused upon delivery.  DAT does not assume responsibility for lost or misdirected product.

Repair  or  replacement  under  this  warranty  is  the  exclusive  remedy  of  the  consumer.    DAT  shall  not  be  liable  for  any  incidental  or 

consequential  damages  for  breach  of  any  expressed  or  implied  warranty  on  this  product.    Some  states  do  not  allow  the  exclusion  or 

limitation or incidental or consequential damages, or allow limitations on how long an implied warranty lasts, so the above limitations or 

exclusions may not apply to you.  This warranty gives you specific legal rights and you may also have other rights that may vary from state to 

state.

Customers outside the United States should contact their local sales office to obtain information on pricing, exchange unit availability, 

instructions, service and warranty/non-warranty replacement or repair.
