Hi Rick

Unfortunately started to reset and retyped the speakers!!!

Also a new laptop so did not ave the original msl file for the 861.

The centre is set as Master in both the speaker and the program. If it is on there is sound through the centre during calibration but not the other speakers. But no comms control.

Centre connected to master output for SL on 861 others connected to the AC12 via the SLave outputs.
