16.2.1 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 Mini 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.
