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 settings 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 ap-
propriate when loading audio from an analog
master, where reducing or eliminating jitter is
more important 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 Press Set.
3 Use the Down and Up switches to scroll param-
eter values.
4 Press Set.
Pitch Memory/Hold
Pitch Memory is useful when resolving the
SYNC peripheral to off-speed, free-running
LTC. When Pitch Memory is enabled, the SYNC
peripheral will remain at a pitch (sample rate)
that corresponds to the last known clock refer-
ence speed.
To enable or disable the SYNC peripheral pitch
memory feature:
1 Select Pitch Hold (“PICH HLd”), using the Set,
Down, and Up switches.
2 Press Set.
3 Use the Down and Up switches to toggle be-
tween On/Off.
4 Press Set. The SYNC peripheral retains the set-
ting, even when powered off, until it is changed.
Turn off Pitch Memory if you want to digi-
tally transfer to another device and to en-
sure the receiving device gets the correct
sample rate.
Also, turn pitch memory off if you are doing
an analog transfer to Pro Tools and want to
ensure that the recording is made at the ex-
act sample rate set by the Session Setup win-
dow.
