The product is warranted to the original purchaser when purchased either directly or through an ASI authorized reseller. The return of ASI product is handled through the original place of purchase of the ASI product. ASI does not warrant secondhand or gray market product. This warranty will be VOID if the serial number has been removed or defaced; or if the product has been altered, subjected to damage, abuse or rental usage, repaired by any person not authorized by AudioScience to make repairs; or installed in any manner that does not comply with AudioScience recommendations. Repair or replacement will not renew or extend the product warranty period. Replacement products will be covered for the remainder of the original warranty period or for ninety (90) days from the date of repair or replacement, whichever is longer.
