I'm new to this so I should apologize before hand. I can't find any specific information regarding how to setup a vocal mic into the Helix LT, with a guitar. I was told it can be done, there's tons of forums and video related to this regarding impedance issues or for the Helix floor. If anyone could help, guide me to a resource of any kind it would be greatly appreciated. Can't find anything related to this in the manual as well. I admit Im a noob, what am I'm missing here. Please help, thanks!!!
