SYNC HD Guide 24
Sample Rate LEDs
These green or yellow LEDs show the current
SYNC HD 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 HD 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 HD 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 the SYNC HD is in Auto
Switch LTC/VITC mode, the decimal point to
the right of “minutes” illuminates.
The SYNC HD Time Code Display always dis-
plays actual incoming time code, regardless of
any External Time Code Offsets settings that are
applied in Pro Tools.
