SYNC I/O Guide60
To set the freewheel duration:
1 Select Freewheel Length (FrEE LEn), using the
Set, Down, and Up switches.
2 Press Set again. The LED Time Code Display
displays the current setting, in frames.
3 Use Down and Up to scroll parameters.
4 Press Set when the desired value is shown.
LTC Output Level/Gain
Adjusts the audio level of the SYNC I/O LTC
output, from –24 dBu to +9 dBu.
See “Example: Adjusting LTC Gain” on page 36
for step-by-step LTC gain instructions.
To set the LTC output level:
1 Select LTC Gain (L7C 6AIn), using the Set,
Down, and Up switches.
2 Press the Set switch again. The LED Time Code
Display shows the current setting, in dBu.
3 Use the Down and Up switches to switch be-
tween the parameter values.
4 When you have chosen your desired option,
press Set.
Servo Gain
This setting provides a user selectable LTC input
gain offset. Selectable from the front panel only,
this parameter can significantly lessen or re-
move jitter on word clock while resolving to
LTC (though it can slightly increase lockup
time).
To set the LTC servo gain:
1 Select Servo Gain (SErVo Gn) using the Set,
Down, and Up switches.
2 Press Set again. The LED Time Code Display
shows the current setting (–001 is the default).
3 Use the Down and Up switches to display an-
other parameter value. Servo gain provides four
gain settings.
4 When you have chosen the desired option,
press Set.
Pitch Memory/Hold
Pitch Memory is useful when resolving
SYNC I/O to off-speed, free-running LTC. When
Pitch Memory is enabled, SYNC I/O will remain
at a pitch (sample rate) that corresponds to the
last known clock reference speed.
To enable or disable SYNC I/O pitch memory
feature:
1 Select Pitch Hold (PICH HLd), using the Set,
Down, and Up switches.
2 Press Set again. The LED Time Code Display
will display the current setting (on or off).
3 Use Down and Up to scroll parameters.
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 re-
cording is made at the exact sample rate set
by the session set up window.
