11.7B TIME CODE START REFERENCE (PAGE 2)

This page sets the internal generator’s starting reference. Use the Up/Down buttons to select one of three options, or use the keypad numbers given below.

∙With ABS Time (keypad 0), the internal generator’s start address is the current ABS address plus any ABS offset (set on Page 3). The generator outputs time code based on the M20’s absolute time track. Note: For time code to appear at the rear panel time code output, the time code track must be input-enabled, the generator must be running, and a formatted tape must be loaded.

∙With TC Track (keypad 1), the current TC track time code becomes the internal generator’s start address. The generator will continue generating the same format code as on the time code track when the input is enabled and the generator is running. If no code exists on tape, no time code will be output or recorded; the display temporarily shows “TC Reference not present” if you try to turn Int Gen on.

∙With User Set (any keypad number >1), the generator will output time code that is synchronous to the absolute time, but starting at an arbitrary address as defined in the next page. The time code will only be generated while the time code track is input- enabled. The generator retains the address at which it was stopped, and continues when re-started. In other words, whenever the generator is running with a User Set TC Start reference, it updates the User Set Start number.

11.7C ABS/START OFFSET (PAGE 3)

This page shows “ABS” if Page 2 is set to ABS, and “START” if Page 2 is set to User Set.

If the Internal Generator is set to ABS, you can enter an offset for the time code output compared to the ABS time.

If the Internal Generator is set to User Set, you can enter a new generator start time. The display shows the current generator location when last stopped in User Set mode.

If the generator is running, this page will show the previous start value, but the cursor will not be displayed as the start time cannot be edited while the generator is running.

Here’s how to edit the ABS/Start offset value:
