Digital Timepiece to the word clock output of the
standards converter, while at the same time slaving
the ADAT to the Digital Timepiece (as well as the
digital audio system to which you are transferring
audio).
THE SMPTE FRAME RATE SETTING
The Digital Timepiece automatically detects the
frame rate of incoming time code. That is, when
the Digital Timepiece is put into a time base mode
that requires an external time code source as the
address master, such as
LTC mode or Video/MTC
mode, it scans the appropriate ports for incoming
time code. As soon as it receives time code, the
Digital Timepiece automatically sets itself to the
proper SMPTE frame rate, based on the time code
it receives.
☛
Automatic detection only occurs when
incoming time code is actually present. Until then,
the frame rate setting will not change.
Similarly, if the SMPTE frame format on the front
panel of the Digital Timepiece is set to 30 when you
choose one of the Digital Timepiece’s video modes,
the frame rate setting will automatically switch
itself to 29.97. If you then feed the Digital
Timepiece non-drop time code, it will remain at
29.97. But if you feed it drop frame time code, it
will automatically switch itself to the
29.97 drop
setting.
turning off auto-detection
If you find yourself in a situation where you would
like to disable the Digital Timepiece’s automatic
frame rate detection, you can do so using the
ClockWorks software. See “Generate signal when
stopped” on page 23 in the ClockWorks manual.
Setting the SMPTE frame rate manually
The following time base modes require that you set
the frame rate manually:
■
Internal
■
Video/Internal
■
Word 1x/Internal
■
Word 256x/Internal
■
Word 1x/Video/Internal
■
S/PDIF/Internal
■
S/PDIF
■
Control Track 1 or 2
■
ADAT
■
DA-88
To set the SMPTE frame rate manually, use the
FORMAT button on the Digital Timepiece front
panel as shown below in Figure 4-3.
Figure 4-3: Setting the SMPTE frame rate manually using the controls
on the Digital Timepiece front panel. This is only necessary for the
time base modes listed earlier in this section. For any time base mode
that relies on an external time code address source, the Digital
Timepiece automatically detects the SMPTE frame rate.
You can also set the frame rate manually using the
Digital Timepiece software applet, called
ClockWorks . In ClockWorks, open the MIDI
Machine Control window from the Windows
menu, and then choose the frame rate from the
pop-up menu provided, as shown in Figure 4-4.
For more information about ClockWorks, see the
separate
ClockWorks User’s Guide that accompanies
this manual.
