9931-EMDE Function Menu List and Descriptions
(continued)
Encoded Dolby (L) and Encoded Dolby (R) selection in Source
drop-down list routes a Dolby encoded pair from any of the card's Dolby
encoders (A up to D) to be the source for the selected embedded output
channel.
(In this example, Dolby Digital Encoder B (L) is the source for destination
Embedded output Ch 1)
Note: Encoded channel pairs selected should only be applied to
companion intact pairs (e.g., signals can be applied to embedded
pair 1/2, or embedded pair 3/4 and so on, but not split to route
through fabricated unrelated pairs such as embedded ch 2/ch 3).
Silence selection in Source drop-down list mutes the selected embedded
output channel. Use this setting for any unused embedded output
channels.
(In this example, Silence is the source for destination Embedded output
Ch 1)
Provides relative gain (in dB) control and peak level display for
corresponding embedded output channel.
Also provides a channel Mute checkbox.
(-80 to +20 dB range in 0.1 dB steps; unity = 0.0 dB)
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
group adjacent to that being enabled or disabled. This control
should not be manipulated when carrying on-air content.
