Latency Synchronization
The minimum audio processing latency is 40 ms. If working in audio
for video environments, it is recommended that you adjust the laten-
cy according to the video frame rate used.
Device Latency
This display shows the current audio processing latency.
Synchronize to Frame Rate
Check this box to increase latency to a value suitable for the video frame
rate set below. The increased latency will be reflected in the "Device Laten-
cy" display (see above).
Video Frame Rate
This parameter sets the video frame rate that the system latency should be
adapted to.
Options: 24, 25, 29.976, or 30 frames/s.
Clocking Modes
Use this section to set up the primary and secondary sync sources
to be used for system synchronization. For details, please also refer
to
in the Hardware chapter.
Current Master Clock
This display shows the clock reference currently used by the hard-
ware and its sample rate.
Master Clock Priority
This parameter selects a priority chain of clock sources – i.e. a primary,
secondary and fallback clock source. If the attempt to synchronize to the
primary source is not successful, the unit will try to sync to the secondary
source instead. If this also fails it syncs to the internal clock as a fallback.
Options:
·
AES 1 Input (1
st
), Word Clock (2
nd
), Intern (fallback)
·
Word Clock (1
st
), AES 1 Input (2
nd
), Intern (fallback)
·
AES 1 Input (1st), Intern (fallback)
·
Word Clock (1st), Intern (fallback)
·
Intern (fallback)
Please note:
In order to sync to an external AES signal, select the appro-
priate clock source and make sure you use the AES 1 input for this pur-
pose.
