7.4.1 Downmix to 5.1

The Downmix to 5.1 section of this panel allows the user to specify the appropriate parameters for the

downmix as shown in Figure 7-15. This section will only be active if the selected channel layouts have

7.1 or 7.0 channels.

Figure 7-15 Downmix to 5.1

The channel layout selected on the Audio panel will dynamically update the headers in the columns of

the Downmix to 5.1 faders. The first fader (i.e. L, R, C, LFE, Ls and Rs) in each control set, known as

Scaling Coefficients, shows the scaling value for each of those channels. The values in these fields, at

the bottom of each column, specify the channel’s contribution to the output mix. The values range from

0.0 to -6.0 (0 to -6.0 dBFS) inclusive. The mixing coefficients for the extra channels (i.e. Lh and Rh in

Figure 7-15), known as Downmix Coefficients, range from 0 to -60.0 (0 to -60.0 dBFS) inclusive or -INF.

INF implies that there is no contribution to the channel (-INF = Negative Infinity). The labels on the

extra channels will update dynamically depending on the channel layout that is selected on the Audio

panel.

The other two columns in each control area are the surround channels (i.e. the two extra channels in the

7.1 channel layout case). The values in these fields specify the supplemental channels’ contributions to

the output mix of the L, R, C, LFE, Ls and Rs channels).

When the phase shift button is activated,

the corresponding channel above it will be phase-reversed

(180 degree phase inversion) before the channel is mixed into the output mix. The downmix levels can

be updated either by clicking and dragging on their vertical faders or by entering the desired downmix

value in the bottom input text fields. If the entered value is outside the minimum or maximum values, the

fader will be positioned to the nearest value. For example, if the entered value is greater than 0.0, the

fader would be positioned to 0.0 and the text field would be updated to 0.0. If the entered value is less

than -60.0, the fader position would be located at the minimum value and the text field would indicate

“INF”.

Note: If the faders in the Downmix to 5.1 sections are altered and the user decides to change the

selected channel layout on the Audio panel, when the Downmix panel is subsequently displayed,

the faders will be changed to the default values for the selected channel layout. The faders will

also change to the default setting for the selected channel layout when the user selects the

button.
