Sorry for the hassle. As it turns out, DOAs need to go back. It's entirely undetermined why this unit is not working. Can you please contact Sweetwater? They'll take care of it.
If you prefer us to contact Sweetwater for you, please send us a note through the contact form on the Kemper Amps website.
Please refrain from providing "customer support", especially in cases where you're just guessing. Thanks - I've deleted all posts above to avoid further confusion.
