If you select ABS-13or ABS-23, use the UP and DOWN keys to select the starting hour. In the illustration above, the starting hour is 0.

•29.97 DF

•29.97 NDF

•25F

•24F

These types will not, of course, affect the type of any timecode which has already been used to stripe a tape.

They are used for the type of timecode which will be produced by the internal timecode generator of

aDTRS unit (DA-98 or SY-88) or the synthesis from ABS timecode of these units.

8.1.3 Selecting a timecode type

The RC-898 can work with a number of different timecode types, as shown by the TC indicators [7].

The 29 on the RC-898 panel is an abbreviation for “29.97”. The DF indicator will light if the time- code is in drop-frame format.The supported types are therefore:

2424fps (cine)

2525fps (PAL/SECAM)

29

29.97

(NTSC color non-drop)

29 DF

29.97

(NTSC drop-frame)

30

30fps (NTSC mono)

30 DF

98 30fps drop-frame (NTSC color)

NOTE

30 fps drop-frame is only supported by DA-98 units.

To select or change the timecode type used by a DTRS unit:

1)From menu group 5, move the cursor to TC Frame and press SELECT:

T C F r a m e M o d e

M a c h i n e 1

3 0 D F

2)Use the SHIFTed UP and DOWN keys (NEXT and PREVIOUS) to select the unit where you will make settings.

3)Use the UP and DOWN keys to change between the following settings:

8.1.4 Setting the generator start time

The DTRS unit’s internal generator can be set in the following way:

1)From menu group 8, move the cursor to Gen Start, and press SELECT:

G e n e r a t e S t a r t T i m e

M a c h i n e

1

0 0 : 0 0 : 0 0 : 0 0

3 0 D F

2)Enter the generator start time using the numeric keypad [16].

3)Press and hold down SHIFT and press ENTER/ LOAD to transfer the value to the display screen.

You can also use the cursor keys and the display screen to set the value here.

NOTES

The frame value at the bottom right of the screen is not set here. The procedure for setting this is described in detail in 8.1.3, “Selecting a timecode type”, and is accessed from menu group 5.

If the timecode source is synthesized ABS timecode, the timecode type may be changed by changing the timecode type of the ABS “timecode”. It is not possible to receive one type and convert it for recording, however. If timecode is being recorded from an external source, thetype cannot be changed.

We suggest that you choose a value such as 00:57:00:00, allowing a few minutes of lead- in on the tape before the program material starts.
