MOTU SMPTE Setup
OVERVIEW
The 828x can resolve directly to SMPTE time code
via any analog input, without a separate
synchronizer. The 828x can also generate time
code via its time code output. The 828x provides a
DSP-driven phase-lock engine with sophisticated
filtering that provides fast lockup times and sub-
frame accuracy. Direct time code synchronization
is supported by AudioDesk and Digital Performer
on Mac OS X. Other hosts, such as Pro Tools, can
resolve to MIDI Time Code generated by the 828x.

MOTU SMPTE SETUP
The included MOTU SMPTE Setup™ software
provides a complete set of tools to generate SMPTE
for striping, regenerating or slaving other devices
to the computer.
CLOCK/ADDRESS
The Clock/Address menu (Figure 10-1) provides
the same global Clock Source setting as in MOTU
Audio Console (“Clock Source” on page 41), but it
includes additional information: each setting
shows both the clock and the address (time code or
sample location), separated by a forward slash ( / ).
To resolve the 828x to SMPTE time code, choose
the
SMPTE / SMPTE setting in the Clock/Address
menu. This means that the system will use SMPTE
as the clock (time base) and SMPTE as the address.
FRAME RATE
This setting should be made to match the SMPTE
time code frame rate of the time code that the
system will be receiving. The 828x can auto-detect
and switch to the incoming frame rate, except that
Figure 10-1: SMPTE Setup gives you access to your 828x’s on-board SMPTE time code synchronization features.
The Reader section provides settings for
resolving to SMPTE time code.
The Generator section provides settings
for striping SMPTE time code.
