I ran about 6 calibrations yesterday and I get all speakers to report angles,distance,levels,x-overs etc... and when I take a calibration disc and play the 5.1 test tracks with 3D mapping on there is zero output from the center channel.Trinnov keeps mapping the center to the left and right as a phantom center.
If I use the calibration I save to position 2 from my first and more consistent measurement session,I have output from the center channel.It seems like depending on where the x-overs are determined,that either Trinnov is not liking where I'm trying to push the x-over down by using the low-pass control for the sub,and it's either resulting in too low of a x-over for the center and it's just completely bypassing the center channel or there is something not working right.
The center channel x-over in these calibration runs ended up at a higher point than the first time I performed the calibrations and none of them resulted with any output from the center channel.I have the mic in the same exact place verified through measurements and the results screens give me the same consistent angles and distances,but the x-overs are completely different and higher than where I had got them before using the same low-pass setting.
I've never had these kinds of inconsistent results and had to try and run so many calibrations with Audyssey Pro.I run it once and it gives me consistent results and sonically sounds the same to me between each calibration run.I also don't get x-over results in the 150- 200hz range with the suggested x-over recommendation.I know Trinnov and Audyssey don't use the same measurement philosophy,but I would still think they would be closer in overall results.
Just my .02 cents
