8 – DTRS synchronization–Machine offsetTASCAM DA-98HR 53Another DA-98HR (the slave) has a tape with sometracks containing video backing music. It is neces-sary to produce an offset between the two so thatwhen the master is played, the music tracks will startat the correct time relative to the dialog and referencetracks.1 Locate the slave tape with the backing music tothe start of the music. The shuttle mode may beuseful here (7.6, “Shuttle operations”).2 Rewind the master to a little before you wantthe music to enter.3 Make sure the slave is ready to accept an “on-the-fly” offset entry as described above.4 Start playing the master DA-98HR.5 When the music entry point is reached, pressthe § or ¶ key on the slave machine to cap-ture the offset point.6 Stop the master, and set the slave into CHASEmode (8.2.3, “Master/slave settings (CHASEmode)”).7 Rewind the master to a little before the musicentry and start playing.The slave machine now follows the transportmovements of the master, with the appropriateoffset, so that the music enters at the rightpoint.8.4.5 Clock modeThere are some circumstances where it may be nec-essary to use independent reference clocks on a chainof DTRS units when TC time mode (see 9.2, “Tapetimecode mode”) is selected.There are two settings, Auto andIndividual (individual).Note that this is only relevant when the time mode isset to TC, rather than ABS (see 9.1, “ABS andSMPTE/EBU timecode”).Auto is the default, and the unit behaves as fol-lows when this is selected.If Individual is selected, the unit behavesas follows:1 Select menu group A, move the cursor toClkMode, and press ENTER:2 Use the § and ¶ keys to select one of the twosettings: Auto and Individual.NOTEThis does not mean that you can use two different wordclocks in a system—it means that the same word clock canbe fed in more than one way to different units in a chain ofDTRS recorders.Copy of video worktape audio tracksConnection fromSYNC OUT toSYNC IN00:57:00:00Start of tape01:00:00:00Start of video01:02:21:18Music entry00:57:00:00Start of tape01:00:00:00Start of music (tapeis cued here)Backing musicPress the § or ¶ key at thispoint.
