Yes I did try that. The calibration disc was just a question to tweak things once I get it working right. I didnt realize til this morning that I am not getting anything out of the sub from the BR test signals, which seems odd since I do get some bass from the sub when watching a BR just not nearly enough, and only on one out of the two analog setttings in the avr. When I get home tonight I will go back to basics and check the cable connections.
