Section 9 – Synchronization with other DTRS units06/97 – 1.00 – 9-32) Use the LEFT and RIGHT keys to select the fieldto be edited (hours, minutes, seconds orframes) and the UP and DOWN keys to changethe value of that field.You can use the function keys as number keys (see5.2.2, “Using the function keys as number keys”)to enter the value directly.You can also change the sign of the offset valuebetween + and - by moving the cursor to the sign.3) Use the ENTER key to confirm the setting.9.3.2 Cancelling machine offsetTo cancel machine offset, simply set the offsetvalue to 00:00:00:00.1) Press and hold down the UP key and press theDOWN key to reset the value in the MachineOffset menu (see above).Machine offset will now be cancelled.9.3.3 Setting machine offset “on the fly”As well as entering an absolute number, it is alsopossible to enter a number “on the fly” as thetapes are playing.1) On the slave machine, select menu group 3,move the cursor to Mcn Offset , and pressENTER.2) Make sure chase mode (see 9.2.3, “Master/slavesettings (CHASE mode)”) is off on the slaveunit.3) Use the LEFT and RIGHT keys to move thecursor to a second “invisible” field to the rightof the frames field4) Locate the two tapes (master and slave) so thatthey have the right offset.You can play the tapes and pause them or carry outthe next operation while one or both tapes is beingplayed back.5) Press either the UP or DOWN key at the correctoffset time to capture and store the offset.The current difference between the master andslave tapes will be be displayed on the bottom lineof the display screen and stored as an offset.9.3.4 An example of setting offsetsA practical example of setting offsets is givenhere.The master DA-98 contains the tape with the dia-log and reference tracks from the video worktape.Another DA-98 (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 willstart at the correct time relative to the dialog andreference tracks.NOTEThere is an “invisible” field immediately to the right ofthe frames field. If you place the cursor there and incre-ment or decrement the value, you can change the time asa whole (as the frame field passes its maximum value,the seconds field will increment).M a c h i n e O f f s e tA U T O O F F S E TNOTESThe value entered in this way can be edited later usingthe technique described above.You cannot determine the offset from an unformattedtape, or if either tape is currently displaying a negativeABS value.Backing musicCopy 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)Press the UP or DOWN keyat this point.
