• Downmixer Source Controls Left Channel Input thru Right Surround Channel Input select the five
source channels to be used for the downmix from the following choices:
• Card Path 1 thru Path 4 Audio Bus Ch 1 thru Ch 16
• Silence
Downmix channels Downmixer L and Downmixer R are available as
sources for output audio channels using the Channel Source controls
described above.
• Center Mix Ratio Control Adjusts the attenuation ratio of center-channel content from 5-channel
source that is re-applied as Lt and Rt content to the DM-L and DM-R
stereo mix.
• 0 dB setting applies no ratiometric reduction. Center channel content is
restored as in-phase center-channel content with no attenuation,
making center-channel content more predominate in the overall mix.
• Maximum attenuation setting (-80 dB) applies a -80 dB ratiometric
reduction of center-channel content. Center-channel content is restored
as in-phase center-channel content at a -80 dB ratio relative to overall
level, making center-channel content less predominate in the overall
mix.
(20 dB to -80 dB range in 0 dB steps; Default = 0 dB)
Note: Default setting is recommended to maintain center-channel
predominance in downmix representative to that of the original
source 5-channel mix.
