I tried setting up my 52TX last night and had two issues that are driving me crazy: (1) I tried using the MCACC to auto-calibrate everything, but the receiver is in another room, so I had to buy an extension cable to make the supplied microphone reach out to the seating position, but I keep getting "mic error" when trying to run the MCACC. The tones start, I get the ambient noise ok, then it starts to analyze and I get the error. I even tried using the microphone without the cable (obviously it was nowhere near the correct listening position) and I still got an error. Any suggestions? (2) I tried to just play some scenes from LOTR and the speakers sound pretty good, but there's no bass coming from the sub. I've tried going into manual speaker set up and speakers are set to "small" and sub is set to "yes" but no luck. It's a Klipsch reference series 10" sub and I have the phase set to 0 and the other nob (forget the label) to 40 (lowest setting) and nothing. I tried moving both nobs to varying degrees and still nothing. Everything is brand new and I just took it out of the box last night and it's got me baffled. Any help on these issues is GREATLY appreciated please!!! Thanks in advance.
