Output Audio Routing/Controls

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
• Group Enable/Disable Controls

BBG-1070-QS Function Menu List and Descriptions
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.
• Audio Output 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, PIP1 input audio is selected as the
output four-group audio.)
• Audio Follow Full Screen (when checked) automatically forwards
audio associated with a full-screen video input whenever full screen is
selected.
Allows enable/disable of embedded audio groups 1 thru 4 on 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.
Using the drop-down list, selects the audio input source to be embedded
in the corresponding embedded output channel from the following
choices:
• Device 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)
• Audio LTC
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 unit 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.
