Is there a Meridian DVD player in the mix?

While everything is in standby, press clear on the MSR. The master speaker should flash non-controller (or something close that will fit on the small display) and the 568 should flash controller. If this is not the case, you might not be wired up correctly.

After pressing clear, turn everything on and try the volume control again.
