Hi, I have a yamaha 1500 driving a Mission 781 pair as my fronts, a Mission 78c Centre, a pair of Mission 78ds surrounds and a Mission Ms10 sub. I tried getting the YPAO to optimise my set-up and at the end of it i dont have any output from my sub. It just sits there with no sound !! I have to do a full reset on the Yamaha and then it comes back to life. What could be the problem ?? Has anyone had a similiar problem ?? Help !!
