From my experience, the calib and trim settings are identical (change one, the other also changes) and permanent. The difference is that one includes the 950's internal test tone and the other doesn't -- which is necessary if you want to use AVIA or Video Essentials instead of the test tone to set your channel levels.

gonk is right. The trim setting are permanent. Very interesting....

That's what I thought. Now, if I just had a better understanding of crossover...

Does it really matter what level the tones are recorded at, as long as they're all at the same level? After all, what you're calibrating to is parity among all the speakers, not an absolute level.
