So I’m thinking I’m going to take a shot at trying to capture a PRIR tonight whether the user manual is available or not. I think based on the discussion here that this plan could work, but any input would be appreciated. I’d be working with a 5.1 system where the two fronts are actually installed in the walls so they aren’t movable. The center channel is under the tv and the rears are mounted behind the sweet spot at but elevated, again not terribly movable. It is also connected to a Denon receiver that does not have 6 analog inputs. My thought to make this work is this: Disconnect all of the speakers from the receiver except the front left. Attach the A16 to one of the 2 channel analog ins. Run the sweeps for the front left, disconnect it and then connect the next speaker in its place and run the sweeps for that. Continue until I’ve captured the whole setup one speaker at a time. This would of course be done with me sitting in the middle of the sweet spot. Do you think this will work? Am I overlooking something obvious?
