Thanks, Bruce. I looked at the Legacy config program again and I'm not finding any spot where speakers can be designated master or slave, nor does it indicate whether the speakers are set to master or slave. From the "Speakers" tab I'm able to set the speaker configuration and designate Small DSP, Large DSP, Large 96.24 DSP, etc. Maybe I'm missing something?? I'll keep looking.

System One: 861v2, 2x DSP6000 18 bit, DSP5000C 18 bit, M2500 System Two: 561, 2x DSP5000 18 bit Storage: 2x DSP6000 18 bit
