Smaart 6, Time Alignment
Is it possible to measure what settings to use for time alignment using Smaart 6? I have a P880PRS headunit and would love to do some tweaking to the time alignment. I also noticed a phase section in the program, what does that do? Can it detect what phase the speakers are playing in so I can adjust the phasing too?
Thanks.

Looking at it Yes. It won't give exact phase, but you can tell if you should invert phase on a specific speaker. The key is to run the speakers full range when setting it.
Look for the initial spike, if up it is in phase at the listening position, if down it is out of phase and you should flip it. Also, for time alignment you are trying to align the spikes of all of the speakers. Don't worry about the sub, it usually isn't affected by TA and is usually the furthest speaker away and the speaker you align the others to.
Just be careful when doing this, you can easily blow your tweeters with too hot of a signal using MLS signals.

t/a affects phase.
Therefore, t/a will have an effect on the phase of the sub.
However, the reason most don't use t/a is simply because the sub is typically the furthest driver away from you and most use t/a only to 'push' the drivers closest to you further away to where the perceived arrival time is equal to that of the sub.
When you break the t/a aspect down to phase, then you really start reaping the benefit of time alignment.
