Getting Started with MIX54
For fairly short pieces of audio program mate-
rial, SMPTE Trigger is acceptable, especially if
the sync master has a fairly stable transport or is
resolved to house sync or a black burst genera-
tor. In this case, the master transport and
Pro Tools will probably not drift very far apart in
such a short period of time.
On the other hand, if the audio piece is several
minutes long, or if the sync master has an unsta-
ble transport (as in the case of a low quality re-
cording deck striped with SMPTE, for example),
SMPTE Trigger alone is probably not an accept-
able solution, since the two systems may drift
apart noticeably over the duration of the source
material.
A better alternative is to use Digidesign’s
SYNC I/O or Universal Slave Driver (USD).
Digidesign Universal Slave Driver
The Universal Slave Driver (USD) is a multi-pur-
pose synchronization peripheral that provides
virtually all of the functions and connections
needed to achieve synchronization to a variety
of devices.
The USD allows synchronization of Pro Tools to
Linear Time Code (LTC), VITC, and Bi-
Phase/Tach while resolving to a video house ref-
erence or other word clock signals. It supports
all major industry-standard clocks and formats
and can also act as a standalone MIDI Time
Code (MTC) or VITC reader/generator.
In addition, the Universal Slave Driver offers ex-
tremely fast lockup, near-sample accurate syn-
chronization, and an exceptionally low-jitter
clock. These features provide professional per-
formance and maximum audio fidelity under a
wide range of synchronization conditions.
Digidesign SYNC I/O
The SYNC I/O can be used with
Pro Tools|24 MIX and Pro Tools|24 systems, as
an alternative to the USD. When used with
Pro Tools|24 MIX and Pro Tools|24 systems, the
SYNC I/O emulates the USD.
