I connected the speakers by using the main line out. Subwoofer and central speaker cable into Sub 1 - Rear speakers cable into R - Front speakers cable into L/L+R. I think it was the front left speaker wouldn't work. Tested the speaker - it was okay. Switched cables all around in different configurations - could not get that speaker to work. It was always the same one that wouldn't work. Tried 2 other speakers unrelated to the Logitech. When I plug into back of Tyros - one speaker doesn't work. Do I need to configure something in the utility part of the Tyros - do I need a mixer - what could be causing this? Would appreciate someone's expertise.

Thank you
