My apologies for the basic question. I am using an ARC12c mixer and am intending to plug in a Roland TD27 drum module into the mixer. I understand that all of the XLR inputs have phantom power when the phantom power button is engaged. Therefore, I would plan to use an active direct box between the Roland TD27 module and the mixer. My question is- can the XLR inputs (labelelled as "Mic") also accept instruments in their input, assuming that a direct box is employed to help match the impedance. I don't want to buy a direct box and then just have to return it because I bought the wrong one or it was an illogical idea to begin with. Thank you!!!
