PreSonus Limited Warranty 

 
 

 

PreSonus Audio Electronics Inc. warrants this product to be free of defects in 
material and workmanship for a period of one year from the date of original retail 
purchase.  This warranty is enforceable only by the original retail purchaser.  To be 
protected by this warranty, the purchaser must complete and return the enclosed 
warranty card within 14 days of purchase.  During the warranty period PreSonus 
shall, at its sole and absolute option, repair or replace, free of charge, any product 
that proves to be defective on inspection by PreSonus or its 

authorized service 

representative

.  To obtain warranty service, the purchaser must first call or write 

PreSonus at the address and telephone number printed below to obtain a Return 
Authorization Number and instructions of where to return the unit for service.  All 
inquiries must be accompanied by a description of the problem.  All authorized 
returns must be sent to the PreSonus repair facility postage prepaid, insured and 
properly packaged.  PreSonus reserves the right to update any unit returned for 
repair.  PreSonus reserves the right to change or improve the design of the product 
at any time without prior notice.  This warranty does not cover claims for damage 
due to abuse, neglect, alteration or attempted repair by unauthorized personnel, and 
is limited to failures arising during normal use that are due to defects in material or 
workmanship in the product.  Any implied warranties, including implied warranties 
of merchantability and fitness for a particular purpose, are limited in duration to the 
length of this limited warranty.  Some states do not allow limitations on how long 
an implied warranty lasts, so the above limitation may not apply to you.  In no event 
will PreSonus be liable for incidental, consequential or other damages resulting 
from the breach of any express or implied warranty, including, among other things, 
damage to property, damage based on inconvenience or on loss of use of the 
product, and, to the extent permitted by law, damages for personal injury.  Some 
states do not allow the exclusion of limitation of incidental or consequential 
damages, so the above limitation or exclusion may not apply to you.  This warranty 
gives you specific legal rights, and you may also have other rights, which vary form 
state to state.  This warranty only applies to products sold and used in the United 
States of America.
