SYNC I/O Guide24
Sample Rate LEDs
These green or yellow LEDs show the current
SYNC I/O sample rate. Pull Up and Pull Down
are available for all sample rate settings, indi-
cated by the corresponding LED. Table 4 (above)
shows the actual sample rates when pulled up or
down.
Generator/Parameter Controls
These four switches provide direct access to
many SYNC I/O functions, including time code
generator settings, PAL/NTSC selection, sample
rate and more. The Time Code LED display
shows the current mode, selected parameter, or
setting.
Time Code Display
This 7-segment, multifunction LED is the
SYNC I/O time code and parameter display.
Time Code The current positional reference (in-
ternal or external), is displayed in hours:min-
utes:seconds:frames. Odd/even field distinction
is indicated using a decimal point to the right of
the frames display. A lit decimal point to the
right of frames indicates an even-numbered
field; no decimal point indicates an odd-num-
bered field. When SYNC I/O is in Auto Switch
LTC/VITC mode, the decimal point to the right
of “minutes” illuminates.
The SYNC I/O Time Code Display always dis-
plays actual incoming time code, regardless of
any Session Start Offsets (External Time Code
Offsets in Pro Tools 6.6.x) that are applied in
Pro Tools.
