I recently moved my home theater setup based on a Pioneer SC-LX82 AV receiver into a new apartment, and now I’m sitting surrounded by cables, trying to figure out why the system keeps throwing a calibration error. Back when it was first set up, everything was configured by a technician, but now I have to figure it out myself. I plug in the MCACC calibration microphone, start the test, and halfway through it says it can’t detect the front speakers — even though they clearly work fine when I play music through them.
I suspect it might be some deep setting like Bi-Amping being enabled, or maybe the wrong speaker configuration/zone is selected, but the Pioneer interface feels like a maze for someone who’s not familiar with it. Guys, any help would be appreciated — maybe someone has a proper manual so I can check the wiring step-by-step and figure out where in the menu I can reset the speaker configuration? Also, could the issue be caused by the calibration microphone itself if it’s been sitting unused in a box in the garage for a couple of years? Is there any way to test it without buying a new one, or is this more likely a software/configuration issue in the receiver itself?
