Chapter 4: Using Pro Tools | SYNC HD 27
Configuring SYNC HD to use Word
Clock or AES/EBU and Video Reference
In scenarios where you want to lock systems to au-
dio clock and also ensure that playback starts at a
frame edge (such as when triggering playback on
multiple Satellite systems), you can configure
SYNC HD to simultaneously use video reference
for frame alignment and Word Clock or AES/EBU
for speed reference. The Video Reference and the
Word Clock or AES/EBU signals must be derived
from the same source (such as a house sync gener-
ator).
To configure Pro Tools to use video reference and
Word Clock from a SYNC HD:
1 In the Format section of the Session Setup win-
dow, select
SYNC HD from the Clock Source
pop-up menu.
2 In the SYNC Setup section of the Session Setup
window, select
Word Clock or AES/EBU from
the
Clock Reference pop-up menu.
3 In the SYNC Setup section of the Session Setup
window, select the appropriate video reference
rate from the
Video Ref Format pop-up menu.
Digital Clock (AES/EBU or Word
Clock) Options
To resolve SYNC HD to external AES/EBU or Word
Clock using Pro Tools:
In the SYNC Setup section of the Session Setup
window, select the appropriate digital clock ref-
erence from the
Clock Reference pop-up menu.
To resolve SYNC HD to external AES/EBU or Word
Clock using the front panel controls:
1 Press the Clock Reference switch to select
Word/AES.
2 Press Set, and use the Up and Down switches to
display Digital Reference (“dI6 rEF”).
3 Press Set. The LED Timecode Display displays
the current digital reference.
4 Press the Up or Down switches to select the dig-
ital clock you want to use.
• AES/EBU (“AES-E8U”)
• Word Clock (“I CLOC”)
5 Press Set.
If the chosen clock reference source is unavailable,
or the current configuration is not valid, the
Locked LED on the right side of the SYNC HD
front panel flashes.
