I have a Spider IV HD150, I want to use the Line Out/Phone directly to my DAW to record. Do I need to disconnect the speaker outputs running to the cabinet before I do this, or is it OK to just connect the Line Out when I want to record? I understand that it will mute the cab speakers with the line out plugged in, that is fine, just don't want to damage anything in the head by leaving the speaker connected and I cannot find anything that says for sure it is OK.
