ok, i absolutely LOVE my sennheiser ew100g2 wireless system. i was using it thursday at a gig for our youth group. we were playing a gig downtown here in abilene called artwalk, very cool. i was playing guitar and not bass for this one, i ran my wireless directly to our soundboard using the xlr out. now when i try to use the wireless through the quarter out i get no sound, but i do get sound using the xlr still. coincidentally when i have an xlr out to our board and the quarter out to my amp it works on both xlr and quarter. so in other words the only time the quarter works is when an xlr is plugged in as well. any suggetions.
