I've been working with the Audiobox VSL 44 and just upgraded to the 18/24. Everything is working fine except this product is advertised as having 8 outputs aside from the mains. But when I go into I/O configuration it uses 1 and 2 as the mains and there seems to be no way to change this. I tried setting up a Sub out using 1 and 2 to see if it program would recognize the difference between the two but it's as if they are one in the same. I know some folks like this but I need all 8 outputs separate which is why I got this unit. Any help is appreciated.
