source in fast wind mode, the tape counter will flash.

If the timecode source is not clock-synchronized with the DA-98, a warning will be shown on the display screen. In this case, although you can record timecode, it is not recommended, as this will probably cause problems later on.

5)Stop the external timecode source, and rewind or reset it to a point prior to where you want recording to begin.

The tape counter will now start to flash.

6)Restart the source.

The tape counter will display received timecode.

7)Press and hold down PLAY and press RECORD. Timecode will now be recorded from the external source onto the timecode track.

If the tape counter was flashing when the TC REC indicator was flashing (the timecode track was armed), the tape counter will now show all hyphens, and nothing will be recorded.

10.5.7 Checking external timecode

There is another way you can check external time- code, as described below. This method is useful for checkingExtTCthe frame rateAbofsincomDiffng timecode, if youTapeTCRelare not sure what frame rate has been recordedGenor is being generat d by the timecode

1) ExtTCGo o menu group E, and move the cursor to

source01:02:48.:1730ND

2)Incoming timecode will be displayed on the bottom line, together with the frame rate of the timecode.

10.6 Video resolution

As explained above, if the DA-98 is to be synchro- nized with a VTR, all units must share a common video reference for the digital audio clocks, gener- ated either by the VTR or from a sync generator.

As well as the sample clock, the timecode can be referenced to a video clock (i.e. the start of each timecode frame is synchronized with each frame

boundary received at theterminal) or can be independent of the received frame clock.

Additionally, in a similar way to timecode rechase mode (page 10-13), the DA-98 can be set to rechaseVidtheeoRvideoeframesolsyncve(muting playback output as it rechas ), or to run freely once sync is achie eon/, ignoringffany breaksMoindtheereceived video sig alof.fre

1) RslvGo to m nu group 5, mo the cursor to Vid

2)Use the LEFT and RIGHT k ys to s lect the frame synchronization mode (on/off) and

the UP and DOWN keys to toggle it a d off.

3)Use the LEFT and RIGHT k ys to s lect the video rechase mode (either freeor re-sync).

10.7 Chasing to timecode

The following sections describe the operation of the DA-98 when chasing to external timecode.

The operation of the CHASE switch is similar to the way the CHASE switch is used when synchro- nizing DTRS units (see 9.2.3, “Master/slave set- tings (CHASE mode)”), but in this case, the machine ID is not used.

10.7.1 Machine ID and timecode

Since a DA-98 with machine ID set to 1 is always a master unit as regards DTRS sync operation, there is no need to make any setting on such a machine if it is to be a timecode slave. As long as timecode is received at the TIME CODE IN connec- tor [37] (the EXT TC indicator is lit), a unit whose machine ID is set to 1 will automatically enter timecode chase mode when the CHASE key is pressed.

However, when a DA-98 unit has its machine ID set to a value other than 1, there is a conflict when
