I had an odd problem with my L1 Model II and B2 Bass Module. I only need 1 for most events, but own 2. Last week, I connected as usual, turned on the power stand, set the volumes and ... no sound. Checked everything, swapped cables. Nothing. Powered off the power stand, waited 10 seconds, powered on: perfect, all night long. Anyone have any ideas what could cause this? I called Bose and they didn't know, since it's certainly not normal, but maybe one of you talented users has experienced this. Thanks.
