Just bought a Yamaha RXV-2500 and tried setting it up.  I did the auto-calibration (YPAO) and noticed that it did not detect my center speaker.  I manually added it and confirmed that it works.  Has anyone experienced this?
Secondly, I have a Dish Network receiver connected to the RXV-2500 via RCA jacks.  The volume level was very low and vocals were inaudible when I use settings other than STEREO and STRAIGHT.  Any ideas?
Thanks.
