LTC Output Level/Gain
Adjusts the audio level of the SYNC HD LTC out-
put, from –24 dBu to +9 dBu.
The SYNC HD shows the following:
The SYNC I/O shows the following:
See “Adjusting LTC Output Level/Gain” on
page 29 for step-by-step LTC level instructions.
To set the LTC output level:
1
Select LTC Level/Gain (“L7C LEUL” on
SYNC HD, or “L7C GAIn” on SYNC I/O), us-
ing the Set, Down, and Up switches.
2
Press the Set switch again. The LED Timecode
Display shows the current setting, in dBu.
3

eter values.
4
Press Set.
Servo Gain
This setting provides a user selectable LTC servo
gain offset. The five choices provide different
servo gain settings to reduce the effects of jitter
when locking to linear timecode. The front panel
Servo Gain settings correspond to the same set-
tings available in Pro Tools:
0000 (LTC 0 - fastest)
Allows the quickest resolv-
ing to incoming LTC, but with greater jitter. This is
the default setting, and should be used when fast
lock ups are critical.
-0001 (LTC 1)
Provides an intermediate fast set-
ting.
-0002 (LTC 2 - average)
Offers a compromise of
lock up time and jitter quality.
-0003 (LTC 3)
Provides an intermediate slow set-
ting.
-0004 (LTC 4 - smoothest)
Offers the lowest jitter
from LTC resolve, but can take six to ten seconds
to achieve full resolve. This setting is most appro-
priate when loading audio from an analog master,
where reducing or eliminating jitter is more im-
portant than lock speed. When using this setting,
be sure to allow adequate pre-roll before punching
in.
To set the LTC servo gain:
1
Select Servo Gain (“SErVo Gn”) using the Set,
Down, and Up switches.
2
