BBG-1002-2UDX-OM (V1.3)
Provides audio down-mix audio routing selections that
multiplexes any five audio channel sources into a
stereo pair.
Note: •
Downmixer sub-tabs offer identical independent controls for both Embedded Path 1 and Path 2. Therefore, only the
Path 1 controls are shown here. Set controls for other path using the respective sub-tab.
•
Downmix L/R channel pair sources are available only within a respective path (e.g., Path 1 downmixed channels can
only be sourced from Path 1).
• Downmixer Source Controls
Left Channel Input thru Right Surround Channel Input select the five
audio bus source channels to be used for the downmix.
Downmix channels Downmixer L and Downmixer R are available as
sources for embedded, AES, or analog audio outputs 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.
• Surround Mix Ratio Control
Adjusts the attenuation ratio of surround-channel content from 5-channel
source that is re-applied as Lo and Ro content to the DM-L and DM-R
stereo mix.
• 0 dB setting applies no ratiometric reduction. Surround-channel content
is restored with no attenuation, making Lo and Ro content more
predominate in the overall mix.
• Maximum attenuation setting (-80 dB) applies a -80 dB ratiometric
reduction of surround-channel content. Surround-channel content is
restored at a -80 dB ratio relative to overall level, making
surround-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 surround-channel
predominance in downmix representative to that of the original
source 5-channel mix.
