same signal or different signals. If they receive the same signal, the references are considered
redundant. Otherwise they are dual references.
(See Redundant and Dual Video References on page 149.)
Audio reference connects at two ports labeled AES REF1 and AES REF2. One or both connections
are connected to a stable AES source at 48
kHz (48,000 samples per second). If AES reference is
applied to both connectors, the connection is redundant.
For more information on reference connections, see the router’s documentation.
Additional Information about Video and AES Reference
For information about output attribute settings and how to set them, review the following
material:
• Video Fields and Frames on page 145.
• About Vertical Timing on page 145.
• SMPTE Standards for Switch Point on page 146.
• External References and Switch Point Configurations on page 146.
• Redundant and Dual Video References on page 149.
Using the Output Attributes Page
To view or modify output attributes of video outputs in a router, select a control card for that
router in the ‘Video Routers’ table at the bottom of the page.
The output attributes page cannot be used for the expansion frame of an expanded router. Use
the corresponding main frame to access the outputs of the expansion frame.
When you select a control card, MRC presents (1) reference options and (2) a table of outputs for
the router. For the sake of discussion, we call this the attributes table.
