• Dolby

®

Encoder Output as Source for

Embedded Channel Output

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 as Source for Embedded

Channel Output

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)

• Gain / Mute Control

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)

• 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 group

adjacent to that being enabled or disabled. This control should not be
manipulated when carrying on-air content.
