Sync recording starts here

When the rehearsal facility is used, the source is cued up and played, and the first few seconds of the track are sampled and looped. The position of the loop can be adjusted.

This section is looped. The MULTI JOG control adjusts the position of the loop

When this offset has been set, synchronized record- ing takes place with the start occurring at the new location:

Sync recording starts at new point

This example shows how the start time can be moved forward, in order to eliminate unwanted “false starts”. It is also possible to “slip” the start time backwards, in order to record a quiet passage that would otherwise not trigger the sync recording facil- ity (this is done by the use of a memory buffer).

As well as being used for changing the start time of synchronized recording, the start of an automatic track division can also be trimmed backwards and forwards in a similar way.

Both the sync start trim and the track start trim can take the same value and can be used in the same recording.

The maximum trim value is 125 frames on either side of the original point (represented by 0), where there are 75 frames in a second (i.e. 1.67 seconds).

4.4.1Rehearsal for synchronized recording

To perform a synchronized recording, using the rehearsal mode to slip the start of the track forwards or backwards:

1Load a recordable disc into the unit and make sure the unit is in stop mode.

2Cue the source material to the start of the source track to be recorded (i.e. in the example above, this would be just before the count-in).

3Press the RHSL key 4 so that the display shows Waiting Sync.

4Start playing the source. When the start of the track is detected (as explained in 4.3.1, “Syn- chronized recording”), the display changes to

Sync RHSL.

5If the rehearsal does not start at the region of the true start point, press the RHSL key once again to “re-arm” the trigger.

6After nine seconds, the message changes from Sync RHSL, and the sampled data loops in a four-second loop. The display shows

Sync 0:0X, where X is the current sec- ond of the loop.

7Stop the source.

8Turn the MULTI JOG control B to adjust the

point of the loop. The display shows:

TRIM = +XXXf or

TRIM = -XXXf, where XXX can be a number between 0 and 125 and changes back to the Sync 0:0x display when the loop restarts.

Every time the trim value is changed, the loop starts replaying from the new start point.

9When the new start point has been set, press the STOP key (H or J).

10Cue up the source material to the original point set in step 2.

11Press the RECORD key (K or E) to enter

record ready mode, and then press the SYNC REC key (L or F).
