What does the E-6 error message mean and how can it be corrected?
The E-6 error message indicates the receiver does not detect any surround speakers connected to it. In a 5.1 configuration you’ll have a center speaker, two main/front speakers, and two rear speakers connected to the surround speaker terminals, not the surround back speaker terminals. Make sure you have your receiver set-up that way and start the YPAO auto-setup process again. This should correct the error message.
