2)Start playing the tape.

3)The sele ted timecode value will be displayed on the bottom line, together with the frame rate of the timecode.

he frame rate displayed depends on the timecode frameTrackrate as recorded on the tape (if TC

has been selected) or on the selected frame rate (if another option has been chosen).

10.3 Selecting the frame rate

The DA-98 can use the following standards for timecode (including timecode synthesized by the ABS to TC facility): 30 non-drop, 30 drop, 29.97 non-drop, 29.97 drop, 25, and 24 frames per sec- ond (fps).

When using the DA-98 to chase to a timecode master, the system frame rate on the DA-98 must match the frame rate of the timecode master, oth- erwise chase operations are not possible.

The frame rate is automatically set when a tape which has been striped with timecode is inserted,

Frameor if power is switched on with a striped tape al dy inserted in the unit. The frame rate

recordTCd FonrathemtapeeMwillodbeeused as the system frame rate.

To change the frame rate in other cases, follow the procedure below:29.97NDF

1) Go to menu group 5, move the cursor to TC

, and press ENTER:

2)Use the UP and DOWN keys to select the frame rate for your project.

10.3.1Pull up and pull down (Fs shift)

When working in film post-production with NTSC telecine equipment, the frame rate of film (24 fps) and the NTSC color frame rate (29.97) do not form a simple mathematical ratio, and the sampling frequencies of either 44.1kHz and 48kHz are therefore affected on transfer back to film.

To FavoidsSthis,hipullftMup andodpulledown functions are provided to adjust sampling frequencies to drop- frame rates, etc. off

1) ShiftGo to menu group 8, move the cursor to Fs

, and press ENTER:

2) PullUse theDownUP a d30NDFDOWN keys to select between

NDF , PullUP29.97 30DF, PullUP29.97DF, PullDown

and off.

The PULL UP/DN indicator by the tape counter [2] will light if the setting is anything other than off.

NOTES

•This setting is not memorized in the backup memory– you must reset it every time the DA-98 is turned off and on again.

•The clock source must be set to INT when using the Fs shift function to pull up, and to VIDEO when using this function to pull down.

•If vari speed is enabled (see 8.5, “Vari speed (pitch con- trol)”, it is not possible to use the Fs shift function.

•When the Fs shift mode is operational, you cannot change the timecode frame rate (see 10.3, “Selecting the frame rate”).

10.4 Timecode input and output

Only timecode (not ABS timing) can be transmit- ted and received via the TIME CODE IN and OUT jacks. ABS timings are used for multiple DTRS unit synchronization.

10.4.1 Timecode input

There are two primary reasons for the DA-98 to receive timecode: when the DA-98 is chasing to timecode, and must receive the master timecode, and when the DA-98 is to record timecode from another unit (but see 10.5.5, “External timecode sources” below).

To view incoming timecode, follow the procedure below:
