We have one of the older C4 Multi Channel Amps feeding 8 zones of audio throughout the house. We have ran one of the RCA outputs from our C4 Leaf 6x6 HDMI matrix into the multi channel amp for audio. The issue that we have ran into is that we need to turn any given zone up to 80-85% volume to hear anything out of the speakers and when we have multiple feeds going (i.e. Apple TV in living room then Roku in Master Bed) the audio from the second feed will play in place of the audio from the first feed and the only way to correct this is to turn off the first feed (i.e. Apple TV in living room) and then turn it back on.
Any thoughts, suggestions and best practices for this would be greatly appreciated!!
