4.2.4 User Presets
Allows the user to save and recall 32 individual unit configurations. Presets 28–32
contain presets stored in factory ROM. When shipped from the factory, presets 1–5
contain a copy of presets 28–32. Each preset can be given a name of up to 12 characters.
A table of factory default presets can be found in Appendix C.
Preset Pending
A special recall preset state allows a selected preset to be recalled at a time, based on
the timecode input. When this has been enabled, the selected preset will be
considered pending until the specified time is reached, and the preset becomes active.
For instance, you might want the Stereo Music preset to take effect at timecode
00:12:22:12.
To do this, use the following procedure:
• Enter 00:12:22:12 in the TC Start Time field
• Recall the Stereo Music preset.
• Choose Yes when asked Recall at Start?
When timecode 00:12:22:12 occurs, the unit will switch to the Stereo Music preset.
There are a few restrictions on the recall preset on timecode feature:
• Once you have selected a start time and a preset, you can’t change the start
time.
