19 – 538 The Audio Montage
An alternative solution is to use Stereo Down Mixing tables. This means that
you can specify how each surround channel should be represented in the
stereo mix by supplying gain coefficients. When the DVD-Audio is played
back on stereo equipment, the surround channels are combined to stereo –
but they are “mixed” according to the coefficients you have specified. Look
at this example:
The two columns show the gain coefficients for each surround channel, for the left and
right signal in the down mixed stereo output:
- The left and right front signals are sent to the left and right channel respectively, with a
slight attenuation.
- The center signal is sent in equal amounts to the left and right channel.
- The left and right surround (rear) signals are more heavily attenuated and sent to the left
and right channel respectively.
- The LFE signal is not included at all in the mixed stereo output.
To set up a Down Mixing table, proceed as follows:
1. Select a table from the Table number pop-up menu.
You can set up 16 different Down Mixing tables. You select for each DVD track which table
should be used. This is done in the DM column in the DVD-A view, see “About the “DM”
column in the DVD-A view list” on page 537.
2. Specify the desired gain reduction for each surround channel in the Left
and Right output columns.
The value fields are pop-up menus, allowing you to choose values from 0 dB to -61.8 dB or
“Off”.
3. You can invert the phase of a signal by ticking its “inverse” checkbox.
