5.7 Audio Modules panel
This panel displays the controls for an audio module that may optionally be installed in a
socket on the AMX-3981 card.
See Section 6 beginning on page 71 for detailed descriptions of all of the available
modules and their associated control panels.
5.8 Dolby Metadata panel
This panel provides resources for managing the flow of Dolby metadata through the AMX-3981.
Multiple layers of tabs allow the user to drill down to the various available controls. For notational purposes, the path
to a particular control panel will be described here as:
[layer 1 tab]
→ [layer 2 tab] → [layer 3 tab]
For example, the panel shown in the figure on the right would be described as:
[Config]
→ [Delay]
5.8.1 Config tab
Input Presence: Status icons are provided to indicate
sources where Dolby Metadata is present and valid. The
following are shown:
• VANC Stream
• RS-422B
• Decoder (grey if not installed)
Source: This area allows source selection.
• The currently-active pathway is shown in green.
Primary: Use this pulldown list to select the primary
metadata source for this path.
The pulldown list shows the same sources appearing in the
Input Presence section. The Decoder source will appear in
red if the module is not installed.
Note: When decoding PCM audio, the Dolby decoder does
not generate any metadata. If a decoder is selected as a
source for a specified metadata path, the generator on the
same path will be automatically turned ON when the
decoder is decoding PCM audio. The content of the
generator must have been previously configured. Refer to
“Generator automated mode” below for details.
