I just purchased the Amplifi 150 and cannot connect any of my Bluetooth devices IOS or otherwise. When I turn the amp on and off the Bluetooth light briefly comes on, but holding down the button for the 2-3 seconds (or 30 seconds for that matter) to enter pairing mode does nothing. The light doesn't come on at all other than when the entire amp is turned on or off, nor can any of my devices communicate with the amp regardless. I like the amp alright even without the app or Bluetooth functionality at all, but I bought it primarily for the apps modeling capability. Is there any way to fix the problem short of sending the amp back to the factory?
