While pluging the mini power pack into the 'line in'. Will I have any contaol over the D8's recording level knob? Sience I am not going in to 'plug in power' does this recording level have an effect on the recordings outcome? Just bought these mics and looking for advice before I head out. Also, Can I plug the 9v box into the plug in power on the D8? If so more power = better recordings right? Damn newbee I am!!!
