HD Video Format
Selects the video reference rate when the Clock
Reference is set to Video Reference (HD).
The following progressive video reference rates
are available from the front panel display:
• Slow PAL 23.976
• Slow PAL 24
• 720p - 23.976
• 720p - 24
• 720p - 25
• 720p - 29.97
• 720p - 30
• 720p - 50
• 720p - 59.94
• 720p - 60
• 1080p - 23.976
• 1080p - 24
• 1080p - 25
• 1080p - 29.97
• 1080p - 30
• 1080i - 47.95
• 1080i - 48
• 1080i - 50
• 1080i - 59.94

MTC Idle Mute
MTC is output constantly whenever the
SYNC HD is generating time code. Optionally,
this output can be muted when time code (LTC)
is idle.
See “MTC Output and Idle Muting” on page 56.
Device ID
Toggles the device ID of the SYNC HD between
SYNC HD (for use with Pro Tools 7.4 or higher)
and SYNC I/O (for use with Pro Tools 7.3 or
lower).
See “Configuring the Device ID” on page 13.
Using Fader Start
The SYNC HD provides six GPI outputs in total,
two TTL-level and four relays. Together, this
combination of outputs makes it possible for the
SYNC HD to provide Fader Start capability.
Fader Start allows faders in Pro Tools to trigger
external devices to play and stop.
To implement Fader Start, Pro Tools maps the
first two visible auxiliary input channels in a ses-
sion to GPI Relay outputs 0 and 1 (first being
left-to-right in the Mix window, top-to-bottom
in the Edit window).
Utilization of Fader Start has specific wiring
requirements. See “GPI Relay Wiring for
Fader-Start” on page 92.
