For each individual channel, there is a 2x1 audio mixer. Each channel is a combination of an X source and
a Y source. This allows for a mono-mix on a single channel, such as a voiceover. Normal use has the Y
source muted, and the X source chosen to pass through the desired channel. Figure 5-2 shows a single
channel mixer stage.
