Note:

Flex Mix input channels Flex Mix 2 thru Flex Mix 16 have controls identical to that described here for Flex Mix 1.

Therefore, only the Flex Mix 1 controls are shown here.

For each Flex Mix input channel, its source should be considered and appropriately set. Unused input channels should

be set to the Silence selection.

• Flex Mix Input Channel Source

Using the Source drop-down list, selects the audio input source to be
directed to the corresponding bus channel from the choices listed below.

Silence

Embed Ch 1 thru Embed Ch 16

AES Ch 1 thru AES Ch 16

Analog Ch 1 thru Analog Ch 8

Dolby Decoder Output Ch 1 thru Dolby Decoder Output Downmix R

• Gain / Mute Control

Provides relative gain (in dB) control and a channel Mute checkbox.

(-80 to +20 dB range in 0.1 dB steps; unity = 0.0 dB)

• Flex Mix Summing Node (Bus) Selector

Each Flex Mix input channel can be fed as desired to any of 16 summing
node buses (Flex Mix A thru Flex Mix P). The flex mix buses can be
routed and processed the same as any other audio input source.

Note: See the examples on the previous page for providing various types

of mixers by applying a common Flex Mix Bus to various input
channels.

Dolby E Alignment – Provides selectable Dolby E alignment for
embedded Dolby E to position the bitstream utilizing the Dolby E
“guard band”. This helps prevent frame errors that may occur in a
bitstream upon switching or editing.

• Dolby E Embedding Alignment Control

For incoming Dolby E data routed to the card audio bus (either over
embedded channels or via AES embedding to the bus), aligns the
embedded Dolby data corresponding to selection. Alignment line as a
result of selection is shown in Status display.

Note: • Where a frame reference is available, it is recommended to use

the Align to Reference selection. This helps ensure that the
correct alignment is achieved even if the video is user delayed or
output format (scaling) is changed.

Refer to “Preferred Alignment for Dolby E in HD Systems”

(http://www.dolby.com/about/news-events/
newsletters-dtvaudio-dolby-e-alignment.html) for more
information regarding Dolby E alignment.

This control applies only to externally received Dolby E data

streams. Card Dolby E encoder (if used) data is automatically
aligned with video to utilize guard band.
