Focusrite Pro Warranty and Service

All Focusrite products are built to the highest standards and should provide reliable performance for 
many years, subject to reasonable care, use, transportation and storage.

Very many of the products returned under warranty are found not to exhibit any fault at all. To 
avoid unnecessary inconvenience to you in terms of returning the product please contact Focusrite 
support.

In the event of a Manufacturing Defect becoming evident in a product within 36 months from the date 
of the original purchase Focusrite will ensure that the product is repaired or replaced free of charge.

A Manufacturing Defect is defined as a defect in the performance of the product as described and 
published by Focusrite. A Manufacturing Defect does not include damage caused by post-purchase 
transportation, storage or careless handling, nor damage caused by misuse.

Whilst this warranty is provided by Focusrite the warranty obligations are fulfilled by the distributor 
responsible for the country in which you purchased the product.

In the event that you need to contact the distributor regarding a warranty issue, or an out-of-warranty 

chargeable repair, please visit: 

pro.focusrite.com/rest-of-the-world

The distributor will then advise you of the appropriate procedure for resolving the warranty issue.  

In every case it will be necessary to provide a copy of the original invoice or store receipt to the 

distributor. In the event that you are unable to provide proof of purchase directly then you should 

contact the reseller from whom you purchased the product and attempt to obtain proof of purchase 

from them.

Please do note that if you purchase a Focusrite product outside your country of residence or business 

you will not be entitled to ask your local Focusrite distributor to honour this limited warranty, 

although you may request an out-of-warranty chargeable repair.

This limited warranty is offered solely to products purchased from an Authorised Focusrite Reseller 

(defined as a reseller which has purchased the product directly from Focusrite Audio Engineering 

Limited in the UK, or one of its Authorised Distributors outside the UK). This Warranty is in addition 
to your statutory rights in the country of purchase.
