together, keeping a strict relationship between the audio and timecode tracks.

In all other cases, we suggest using either the DA- 98’s internal generator or timecode from tape. If you use these as sources, there will be no jitter problems, and any problems of synchronization with the digital audio clock are eliminated.

NOTE

When recording timecode from an external digital source, make sure the digital clock of the DA-98 and that of the external source are synchronized, as explained in 4.2.3, “Word clock connections” and 4.2.2, “Video connections”. A warning message will appear if the timecode source and the DA-98 are not synchro- nized, but timecode can still be recorded. However, the resulting timecode recording will probably cause syn- chronization problems in the future.

When recording timecode from a timecode

generator, make sure that there is a common video reference for both the DA-98 and the gener- ator (set the CLOCK of the DA-98 to VIDEO).

When recording timecode from another DTRS

unit, synchronize the two units using ABS chase (setting the timecode/audio source unit to be a slave unit as described in 9.2.3, “Master/slave set- tings (CHASE mode)”). After the two units have been synchronized in this way, timecode and audio can be transferred together.

When recording timecode from a digital source

(audio or video), make sure that the DA-98 and the other unit are locked to a common word (audio recorder) or video (video recorder) clock refer- ence. After the two machines have been synchro- nized in this way, timecode and audio can be transferred together.

When recording timecode from an analog

recorder, feed the analog recorder or its external synchronizer and the DA-98 with a common video source, and use the video resolve function of the analog recorder or synchronizer, if this is provided.

If the analog recorder has no video resolve func- tion, it may have a timecode chase function, which can be driven by any timecode source from the following list:

timecode already recorded on an audio track of the DA-98

timecode recorded on other DTRS units, using ABS chase with the DA-98

timecode recorded on any other recorders syn- chronized with the DA-98

a timecode generator, video-synchronized with the DA-98.

NOTE

Do not use any timecode recorded on the DA-98’s dedi- cated subcode track as the timecode master when trans- ferring timecode from an analog recorder.

If your analog recorder cannot chase to external timecode, you must first record the timecode from the analog recorder on an audio track of the DA- 98 and then transfer the timecode to the dedicated timecode track.

Timecode recorded on the audio track in this way is synchroniz d to the audio clock, and can subse- quently be transferred (through patching) to the timecode track.

10.5.6Recording timecode from external sources

1)Set the TimeModeto TC(see 10.1.3, “Selecting TC or ABS timing”).

2)TCSet the timecode record source to External

(see 10.5.1, “Selecting the timecode source”).

3)Press the TC REC switch to arm the timecode track.

4)Start the external source to check the status of the external timecode.

If no external timecode has been received since the DA-98 has been switched on, the tape counter will show all hyphens.

If external timecode has been received since the DA-98 has been switched on, but is not currently being received, the tape counter will flash.

If the external timecode is currently being received at normal (play) speed, the tape counter will show the value of the timecode currently being received. If the external timecode is being received from a
