Service Request

You will receive a response to your RMA request within 1 business day. The Audio Precision factory is open Monday through Friday, with exceptions for U.S. holidays.

Please do NOT send your instrument until your service has been scheduled and you have been issued an RMA.

Before requesting service, please download and run the Self Test or Performance Check for your instrument. This will help you to verify if the problem is indeed hardware related, and will aid us in identifying the issue if you do need to request service.
