In this manner you could, for example, automatically perform a ‘hands - free’ camera switch to show someone
who begins speaking, and then automatically switch back again when he stops.

16.10.3 ROUTING TAB
A main tab labeled Routing appears in the Configuration panel for all sources (Figure 213). The controls in
this group determine output routing of the various channels supplied as inputs to the various output mix
busses (
MASTER, AUX 1 , etc.) Let’s discuss what an audio bus is and its uses before proceeding.
B USSES AND O UTPUTS
Consider a very basic audio mixer. Its main audio signal path, from input to output, is properly called the
‘ master bus .’ Sound supplied to one or more inputs is placed on this master bus (in the jargon of audio
processing, this is called a ‘send’), which ultimately flows to output connectors.
Slightly more advanced mixers often provide more than one ‘send’ for individua l inputs. For example, the
sound from all inputs may be sent to the master bus, comprising the ‘master mix’. A different mix, sometimes
called a ‘sub
- mix’, might also be created by sending certain signals to a secondary (‘auxiliary’, or ‘Aux’) bus.
Hint: A secondary mix, prepared on an Aux bus, can serve
many purposes. For example, you might wish to record a
mix with all sound from talent microphones but that
excludes any sound effects or music.
Let’s summarize what we have learned so far: A ‘ send ’
pipes audio signals from an input to a discrete pathway
called a
‘ bus ’. Multiple sends can be used to place sound
from a given source onto one or more internal busses.
What else should we know?
Each audio bus is discrete. Each can be directed along
different output paths. And even when the blend of signals
it carries is otherwise identical to another bus, it can be
processed separately. Thus its levels, equalization, and
compressor/limiter settings can be unique.
The Audio Mixer provides four primary audio busses. These
are identified in the Audio Mixer as:
• MASTER
• AUX 1, 2 and 3
The Audio Mixer provides controls for each of these busses,
allowing you to manage levels and signal processing. It is
important to understand the distinction between
busses
and outputs . Now that we understand the former, let’s
consider the latter.
