Chapter 4: Using SYNC I/O 49
Generator Start Time
To set the generator start frame:
From Pro Tools:
Configure the Session Setup window as appro-
priate for your system and the current project.
Refer to the Pro Tools Reference Guide for specific
instructions.
From the front panel:
1 Press Set, and use the Up or Down switches to
display Set Gen (SE7 6En).
2 Press Set. One of the time code fields displayed
will be flashing.
3 Press Up or Down to lower or raise the cur-
rently flashing value.
4 To set a time code setting and advance to the
next field, press and release Down and Up si-
multaneously.

SYNC I/O retains the setting, even when the
unit is powered off and on again, until you
change it.
LTC Generation/Regeneration
Regenerating LTC
SYNC I/O will regenerate LTC whenever the ex-
ternal positional reference is moving at normal,
1x forward speed (±10%).
Make sure LTC is correctly routed as explained
in Chapter 2, “Installation and Configuration”.
If you need to adjust the level of the SYNC I/O
LTC output signal, see “Example: Adjusting
LTC Gain” on page 36 for instructions. You can
also adjust the SYNC I/O LTC servo gain, as de-
scribed in “Servo Gain” on page 60.
To regenerate LTC
From Pro Tools:
In the Sync Setup section of the Session Setup
window, select any external positional reference
(except Generate).
From the front panel:
Press the Positional Reference switch to select
an external positional reference (do not select
GENERATE).
From SYNC I/O Setup software utility
(Windows only):
Select an external positional reference from
the SYNC I/O Setup Positional Ref pop-up (ex-
cept Generate).
SYNC I/O regenerates LTC as soon as it receives
a valid positional reference signal.
Generating LTC
In Generator Preset mode, SYNC I/O can gener-
ate LTC using either an external or internal
clock reference. Make sure LTC is correctly
routed and that all your other gear is properly
configured before you begin. See “Example: Ad-
justing LTC Gain” on page 36 for SYNC I/O LTC
instructions. If necessary, adjust the input level
for the destination device.
