Settings for Bose L1 System 2

Hi there, I use the same system for my performances and found it quite hard to get the setup right as niether Bose nor TC Helicon seemed to know how the other units work! I suppose it's because both are quite new products.
Anyway I can only tell you how I have mine set (there may be a far better way, and I'm still looking for it).
I'm assuming that as well as the L1 mkII, you also have the T1 Tonematch and that you've worked out which cables go where... As far as the sound to the T1 goes, I simply set it up as if the Voicelive2 wasn't there. ie if I'm using my SM58 mic into the VL2 then that's what I set the T1 to accept as an input instrument. I've tried to tinker with the settings to see if I could improve on the sound but nothing sounds as good as the appropriate presets.  The complicated bit comes I suppose, if you are using a guitar etc to create your harmonies, unfortunatly I can't help at all there as I don't use one, I set them using the input from my backing tracks played from a laptop and then mute the music coming out on the return so that I still get the same clear rich sound without the tangle of music.
Hope this has helped in any way, and if if can be of any other assistance, let me know.  Oh yeah, and let me know if you find anything out about these great units. As I said, there doesn't appear to be many of us out here using these, so it's good to know I'm not alone lol
