Pioneer Elite VSX-92TXH Help

[doctorD]

Greetings,

I recently purchased the Pioneer Elite VSX-92TXH Receiver and was blown away by the default sound out of the box. Here is my problem...instead of manually setting up preferences, I used the automatic setup for surround sound "MCACC & Full Band Phase Control" feature (auto setup using the provided microphone). After performing this, the audio doesn't sound the same. The receiver always shows PCM for any movie that is playing and any audio selection for the movie. Anyone familiar with this receiver know if there is a way to go back to the default setting...or know how I can remedy this issue? Thanks in advance for your help!
