Yes, I have configured the HD621 using the Meridian Configuration program for 2-channel system. I inserted my sources and the speakers and stored the settings.I have not found any settings for the comms. Everything is turned off and on again. I pressed CLEAR button on the remote and the master speaker displayed that it is controller. The HD621 still doesn’t respond to the MSR command.
