INSTALLING THE 896MK3 HARDWARE
32
Some example scenarios are demonstrated below.
Simple AES/EBU input transfer (no rate convert)
Figure 4-14: Slaving the 896mk3 to an AES/EBU device. For the
896mk3’s clock source, choose ‘AES/EBU’.
AES/EBU input with rate conversion
Figure 4-15: Rate-converting AES/EBU input.
AES/EBU input with word clock
Figure 4-16: 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 4-17, are briefly summarized in the
following sections. For further details, see “Sample
Rate Convert” on page 46.
Figure 4-17: The Sample Rate Conversion option in MOTU Audio
Setup gives you access the AES/EBU output clock options.
None
To make the AES/EBU output sample rate match
the System sample rate, choose None (Figure 4-17).
No sample rate conversion occurs when this setting
is chosen.
AES Out slave to AES In
To make the AES/EBU output sample rate match
the sample rate currently being received by the
896mk3’s AES/EBU input, choose AES Out Slave to
AES In (Figure 4-17). This setting requires a
connection to the 896mk3’s AES/EBU input from a
device that is transmitting an AES/EBU clock
signal.
☛ Be careful when both the 896mk3’s AES/EBU
input and output are connected to the same
external device: this option is likely to create a
clock loop.
AES/EBU Out options
Choose the desired AES/EBU Out sample rate
options (Figure 4-17) when the desired AES/EBU
output rate needs to be completely different than
the system clock rate or the AES In clock rate.
