I have a gig tomorrow night, they have just asked for a speaker to be located outside 50 feet away, there are some yard games and a patio there, I am running my MC6000 through a driverack pa is there a quick easy way to get a full range signal out to that speaker, wireless is not an option, MC6000 has booth outputs, but they are stereo only any suggestions, I have nowhere I can purchase any gear before this event,
