Note: •
Default factory preset routing routes embedded Ch 1 thru Ch 16 to bus channels Audio Bus Ch 1 thru Ch 16.
•
Bus Ch 2 thru Bus Ch 16 have controls identical to the controls described here for Bus Ch 1. Therefore, only the
Bus Ch 1 controls are shown here.
• Bus Channel Source
• Channel Mute/Phase Invert/Gain Controls
and Peak Level Display
• Bulk (Master) Audio/Video Delay Control

9903-UDX-ADDA Function Menu List and Descriptions
(continued)
Using the Source drop-down list, selects the audio input source to be
routed to the card bus channel from the following choices:
• Embedded input channel 1 thru 16 (Emb Ch 1 thru Emb Ch 16)
• AES input channel 1 thru 16 (AES Ch 1 thru AES Ch 16)
• Analog input channel 1 thru 16 (Analog Ch 1 or Analog Ch 2)
• Input Flex Bus summing nodes A thru P (see Input Flex Mix (p. 3-23)
• Silence
Note: AES pair and analog channel count are dependent on rear I/O
module used.
Provides Mute and phase Invert channel controls, as well as peak level
meter for each output channel. (Meter shows level as affected by Level
control.)
Gain controls allow relative gain (in dB) control for the corresponding
destination Embedded Audio Group channel.
(-80 to +20 dB range in 1.0 dB steps; unity = 0 dB)
Note: Although the card can pass non-PCM data such as Dolby
AC-3, setting the gain control to any setting other than default 0 will
corrupt Dolby data.
Audio Delay – Provides bulk (all four groups/master) and individual
card audio bus channel delay offset controls and delay parametric
displays.
Bulk Delay control adds bulk (all four groups) audio delay from any video
delay (net audio delay offset setting adds delay in addition to any delay
included by other actions). This control is useful for correcting lip sync
problems when video and audio paths in the chain experience differing
overall delays. (-33 to +3000 msec range in 0.01-msec steps; null =
0 msec).
Large rapid changes in bulk delay (> 500 msec) can result in
momentary full-scale noise burst on output processed audio.
This burst can damage monitors or other equipment if not
considered. Gain on output should be reduced if
performing large adjustments to delay.
