Is the sub out affected by line level voltage adjustment?

Did you try it? (Assuming you have an ultra and a sub.)
The difference between the lowest and highest should be more than apparent.
Not got a sub myself. Might be on my xmas list...
 
It shouldn't make a difference. If it did I would consider it a bug.

The input sensitivity of the sub and the power amp can be totally different. There's no point in linking those settings in any way.
