 I'm pretty sure Bruce doesn't mean to use the line in/out on the pc, but rather line in/out on the m-audio... specifically, the unbalanced ones...
I didn't read much above to see exactly what you're doing, but assuming youp're looking to run scans the way most of us do, albeit in your car, I think you'll want to send REW's (or TrueRTA's for that matter) output to your system via the line out (unbalanced) on the m-audio, so this way to capture that output's characteristics in the calibration file.
Bruce's point is that then switching from the unbalanced line in to the balanced "mic" in with the phantom power will introduce errors, but so small as to be negligible...
It certainly looks (from the specs) that the balanced input on the m-audio cannot handle the full scale input from it's own balanced output... |
EXACTLY! and yes tnx bruce.
to summarize, i have 2 choices for a calibration loop-
1)unbalanced rca out to TS input in the combo jack
2) trs balanced out to xlr in into combo jack
Obviously the measurements will be done with the rca out to the line in of the head unit and the mic will be xlr. so it seems from the above discussion that the appropriate calibration loop is #1 above. yes?
