FIGURE 260
It is important to understand the distinction between busses and outputs. Now that
we understand the former, let's consider the latter. For TriCaster purposes, an output
may be physical, or virtual – i.e., it may involve a connector on the rear panel, or not.
For example, the audio recorded by TriCaster does not necessarily require an output
connector.
Note: Audio inputs and outputs for TriCaster Mini models are stereo. Audio can be routed
to the Master 2 and Aux 2 busses, however, for internal use (i.e., sound on these tracks
will be captured if you configure an Isocorder recording to include them).
FIGURE 261
The important thing to realize is that the audio content of any bus may be directed to
one or more outputs or, in some cases, to none at all, and – that this is all up to you.
By default, the sound from the primary busses is routed to physical outputs as shown
in the following table.
