STRIPING SMPTE

Along with its other capabilities, your Express interface is

a SMPTE time code generator. It generates an audio form

of SMPTE time code called Longitudinal Time Code

(LTC).

Use the procedure below to generate new code from

scratch:

1 Make the audio cable connections shown in Figure 2-6

on page 13.

We recommend that you do not pass the time code output

from your Express interface through a mixer or any form

of signal processor. If you must go through a mixer, be sure

equalization is ﬂat.

2 Launch Clockworks (or, under Mac OS 9, the

Express Console software).

3 In the Sync tab (or, under OS 9, in the Sync/MMC

window) set the sync mode to Internal.

4 If you are recording time code on a tape deck, and your

tape deck has dbx noise reduction, be sure to defeat the

noise reduction on the track you are recording time code.

5 Enter a SMPTE start time.

6 Choose the desired frame rate.

7 Adjust the SMPTE output volume.

The goal when striping SMPTE is to get the VU meter on

the tape deck to read approximately –3. If you want to test

the level, set the clock mode to Internal and use the Start

and Stop buttons to make your Express interface generate

time code, and then meter it with your mixer.

8 Roll tape.

9 Click Start.

Striping will begin at the frame you speciﬁed in

ClockWorks. The time code display will begin to roll.

While striping, you can switch to another tab, or even Quit

ClockWorks.
