9902-DC-4K 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: •
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.
•
For each channel, its source and destination should be considered and appropriately set. Unused destination
channels should be set to the Silence selection.
• Embedded Audio Output Input Source
Selects the four-group embedded audio to be embedded in the output
embedded SDI audio (and HDMI Ch1 - Ch8 embedded audio).
(In this example, In A quadrant input audio is selected as the output
four-group audio.)
• 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 (Emb) Ch 1 thru Ch 16
• Built-in Tone generators Tone 1 thru Tone 16
(all are -20 dBFS level; freq (Hz) in ascending order are 100, 200, 300,
400, 500, 600, 700, 800, 900, 1k, 2k, 4k, 6k, 8k, 12k, and 16k)
• 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 this card 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.
