I need to connect a Roland TD 27 drum module to my Studiolive AR12c mixer. In order to do so, I will need to purchase a direct box to place between the drum module and the mixer, and I am trying to decide between an active and passive model. If I get an active model, it would be nice to just use phantom power from the mixer to power the box. My question is- what inputs in the Studiolive AR12c mixer have phantom power? Is it just the XLR mic inputs or do the TRS inputs have phantom power as well? Do all channels (1, 2, 3, 4, 5/6, 7/8, etc) have phantom power or only certain channels? Thank you.
