These three AES/EBU input scenarios are
summarized below.
Some example scenarios are demonstrated below.
Simple AES/EBU input transfer (no rate convert)
Figure 3-13: Slaving the 896mk3 to an AES/EBU device. For the
896mk3’s clock source, choose ‘AES/EBU’.
AES/EBU input with rate conversion
Figure 3-14: Rate-converting AES/EBU input.
AES/EBU input with word clock
Figure 3-15: In this scenario, the 896mk3 and other AES/EBU device
are both resolved to one another via a third master word clock
source.
Clocking scenarios for AES/EBU output
The 896mk3 AES/EBU output can also employ
sample rate conversion. The output options, shown
below in Figure 3-16, are briefly summarized in the
following sections. For further details, see “Sample
Rate Convert” on page 40.

Setup gives you access the AES/EBU output clock options.
