GENERAL PROCEDURE
Use the procedure below to generate new code
from scratch:
1
Make the audio cable connections shown in
Figure 3-25 on page 28.
We recommend that you do not pass the time code
output from the Digital Timepiece through a mixer
or any form of signal processor. If you must go
through a mixer, be sure equalization is flat.
2 If you are regenerating time code from an
existing source, make the audio connections
shown in Figure 3-24 on page 28.
3 Set the Digital Timepiece to the appropriate
time base mode. For a review of the various modes,
see “Summary of synchronization modes” on
page 35. Here are a few common situations and the
appropriate time base settings for each one:
For more information, see “Choosing a time base
mode” on page 34.
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 If you are striping in one of the Digital
Timepiece’s internal modes, set the SMPTE start
time in the main counter of the MMC controller
that you have set up to control the Digital
Timepiece (ClockWorks, a MMC compatible
sequencer or other software program, or a
hardware MMC controller) to cue the Digital
Timepiece to the desired SMPTE start time.
We recommend giving yourself at least 15 seconds
of pre-roll from where you will actually begin
working in the time code. To be safe, record at least
a minute of pre-roll — just in case you decide later
to add more material at the beginning of the cue.
6 If you are striping in one of the Digital
Timepiece’s internal modes, choose the desired
frame rate on the Digital Timepiece front panel (or
from the MIDI Machine Control window in
ClockWorks).
7 If you are running ClockWorks, adjust the
SMPTE output volume with the output level
controls in the MIDI Machine Control window.
8
Roll tape (or other record destination).
9
Initiate striping by doing one of the following:
■
Press the play button in Clockworks’ main
transport controls.
■
Press play on your MMC controller, sequencer
or other transport device that you are using to
control the Digital Timepiece.
■
Start your external time code source (if
applicable).
■
Press the STRIPE button on the front panel of
the Digital Timepiece. This always starts at zero
hours, minutes, seconds and frames (0:00:00:00)
— and only if the Digital Timepiece is in a time
base mode that makes it the address master (one of
the
Internal time base modes).
10 Striping will begin.
