+one of those you can select the appropriate preset.

<title>The audio map</title>
<para>
Down the left-hand side of the map is the list of audio channels in
the currently-selected piece of content. Along the top is each
-channel in the DCP. A checked box means that the corresponding
+channel in the DCP. A green box means that the corresponding
content channel will be copied into the corresponding DCP channel.
</para>
+<para>
+When content channels are copied into DCP channels they can be done
+with variable gain. If, for example, you want to copy a channel
+as-is, you can set a gain of 0dB. Alternatively, if you want to mix
+two channels into one, you may want to use a gain of -6dB on each one
+to prevent clipping when the two channels are added.
+</para>
+
+<para>
+The green boxes of the audio mapping view tell you (very roughly) how
+much gain is applied to each channel. A full-height box means 0dB
+(i.e. unity) gain. Any less height indicates lower gain.
+</para>
+
+<para>
+To map one channel to another with 0dB gain, click in the empty box
+and it will turn green to reflect the mapping. A second click will
+turn the mapping back off. To set some other gain, right-click on the
+box to open the gain menu. This allows you to set
+<guilabel>Off</guilabel> (no mapping or negative infinity gain),
+<guilabel>Full</guilabel> (0dB gain), -6dB gain or
+<guilabel>Edit</guilabel> which allows you to set the required gain
+precisely.
