9902-UDX-FS Function Menu List and Descriptions
Output Audio Routing/Controls
Provides an audio crosspoint allowing the audio source
selection for each embedded audio output channel.
Also provides Gain, Phase Invert, and Muting controls
and peak level meters for each output channel.
Note: •
Output Audio tab has identical independent controls for both Embedded Path 1 and Path 2 using the Path 1 / Path 2
sub-tabs. Therefore, only the Path 1 controls are shown here. Set controls for other path using the respective sub-tab.
•
Embedded Ch 2 thru Embedded Ch 16 have controls identical to the Source, Gain, Mute, and Invert controls
described here for Embedded Ch 1. Therefore, only the Embedded Ch 1 controls are shown here.
•
Although either path can embed from, and de-embed to, discrete audio interfaces (and embed/de-embed to and from
inter-path selections), delay/latency differences between paths should be considered to avoid unexpected A/V delay
(“lip sync”) issues.
• Group Enable/Disable Controls Allows enable/disable of embedded audio groups 1 thru 4 on card
program video output to accommodate some legacy downstream
systems that may not support all four embedded audio groups.
Note: Changing the setting of this control will result in a noise burst in all
groups. This control should not be manipulated when carrying
on-air content.
• Embedded Output Channel Source Using the drop-down list, selects the audio input source to be embedded
in the corresponding embedded output channel from the following
choices:
• Card Audio Bus Ch 1 thru Ch 16 (Path1 or 2)
• Built-in Tone generators Tone n
(-20 dBFS level tone generators with n being frequencies of 100, 200,
300, 400, 500, 600, 700, 800, 900, 1k, 2k, 4k, 6k, 8k, 12k, and 16k)
• Flex Bus A thru P mixer sum node outputs
• Audio LTC (Path1 or 2)
• Downmixer L (Path1 or 2)
• Downmixer R (Path1 or 2)
• Embedded Data L and R (Path 1 or 2) (SMPTE 337
non-PCM data embedding with option +ANC)
• Channel Mute/Phase Invert/Gain Controls
and Peak Level Display
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 9902-UDX-FS can pass non-PCM data such as
Dolby
®
E or AC-3, setting the gain control to any setting other than
default 0 will corrupt Dolby data.
