12 MOTU SMPTE Setup

OVERVIEW

The 8pre can resolve directly to SMPTE time code

via any analog input, without a separate

synchronizer. The 8pre can also generate time code

via any analog output. The 8pre 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.

Any analog input and output on the 8pre can be

used for time code (LTC) input and output,

respectively.

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 12-1) provides

the same global Clock Source setting as in MOTU

Audio Setup (“Clock Source” on page 30 in the

8pre manual), 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

8pre 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 8pre can auto-detect

Figure 12-1: SMPTE Setup gives you access to your 8pre’s on-board SMPTE time code synchronization features.

The Reader section provides settings for

resolving to video and/or SMPTE time code.

The Generator section provides settings

for striping SMPTE time code.
