SYNC HD Guide24
Loop Master Indicator
When lit, this LED indicates that the SYNC pe-
ripheral is the Pro Tools Loop Master device.
Sample Rate LEDs
These green or yellow LEDs show the current
SYNC peripheral sample rate. Pull Up and Pull
Down are available for all sample rate settings,
indicated by the corresponding LED. Table 4
(below) shows the actual sample rates when
pulled up or down.
Generator/Parameter Controls
These four switches provide direct access to
many SYNC peripheral functions, including
time code generator settings, PAL/NTSC selec-
tion, sample rate and more. The Time Code LED
display shows the current mode, selected pa-
rameter, or setting.
Time Code Display
This 7-segment, multifunction LED is the SYNC
peripheral 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 peripheral is in
Auto Switch LTC/VITC mode, the decimal point
to the right of “minutes” illuminates.
The SYNC peripheral Time Code Display always
displays actual incoming time code, regardless
of any External Time Code Offsets settings that
are applied in Pro Tools.
