Asking about the old, discontinued M2000XL power pack by Dynalite. Is the power pack able to do both symmetrical and asymmetrical output distribution? I ask because in the photos in find online, I don't see the usual switch for selecting A:B (ratio / asymmetric) or A+B (combine / symmetric). If it can, then, how do you select between the two different modes since there isn't any selector for it?
Anyone have a operation manual that you can share?
