5 MQA Pass-through (applies only to Coaxial and Optical
Sources): Enable MQA Pass-through for the M66 to act as MQA
decoder or renderer when MQA certified CD player or other MQA
certified devices are connected to coaxial or optical input ports.
Disable AV Mode for MQA Pass-through to be enabled.
6 A/V Mode: By connecting your TV or other video sources to your
M66 through analog, coaxial, optical or HDMI input ports, you
can listen to your favorite shows or movies through your BluOS
system. Grouping multiple BluOS devices from one of these inputs
can require an abundance of network traffic. A/V mode creates a
short and unobtrusive buffer to your audio to ensure your BluOS
system stays in sync with your video even with slower or cluttered
networks. When using coaxial and optical sources, MQA Passthrough
must be disabled for A/V Mode to be enabled.
