11.2.1  Audio Routing Channels 

Before further discussion of CobraNet transmitters and receivers, terminology useful for specifying audio channels 
within a bundle needs to be introduced. Somewhat obviously, these channels are called the Audio Routing 
Channels. On a Hono CobraNet interface, audio routing channels 1–16 map to input channels 1–16. Similarly, on 
the output side audio routing channels 33-48 map to output channels 1–16.
