CONFIGURING THE AUDIO SETTINGS
The SMPTE 272M and 299M standards permit up to four groups of four audio channels to be embedded
into the serial digital video bitstream. The card de-embeds two groups of audio from the serial digital input
video, and uses them as the source for re-embedding on the serial digital output video. The "-AES4"
versions of the card also have four discrete AES inputs that can be selected as the source for re-
embedding.
The Audio menu items are used to configure the de-embedder and embedder groups,
sample rate converters, and to adjust the audio throughput delay. The chart below shows the items
available in the Audio menu. Sections 6.8.1 to 6.8.8 provide detailed information about each of the menu
items. The 7710XUDC-AES4-HD offers simultaneous up-/cross-conversion and down-conversion, and
has a subset of identical menu items (the Audio - DC menu items) for its down-converter. For the sake of
brevity, only the main Audio menus will be included in this manual.
