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, either 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 package. Proof of purchase

must be presented in the form of a bill of sale, canceled check or some other positive proof
that the product is in within the warranty period. Presonus reserves the right to update any

unit returned for repair. Presonus reserves the right to change or improve 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 broach 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. For warranty information in all other

countries please refer to your local distributor.
