Installation guide

TDM Installation Guide40
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 Uni-
versal Slave Driver.
The 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), external video black
burst, or word clock signal. 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.
