8 – DTRS synchronization–Digital dubbing54 TASCAM DA-98HR8.5 Digital dubbingWhen you copy tapes between DTRS units in thedigital domain, there is no loss of quality. A “work-tape” or copy is therefore indistinguishable from theoriginal (also bear in mind that the media used byDTRS units is relatively low-cost, so making back-ups is in all ways a painless procedure).You may want to exploit these features of the DTRSsystem to make archive copies, and “safety copies”of important material (see 1.5, “Recommendedtapes” for our suggestions on tape use).NOTEWhen you copy tracks from DA-88 units, the input wordlength should be set to 16 bits.You cannot copy from a source tape with one sampling fre-quency to a destination DTRS which does not supporthigh-frequency sampling frequencies, or from an HR tapeto a DTRS unit set to normal resolution (this always meansthe DA-88, DA-38 and DA-98 units).1 With the power to all units turned OFF, makethe synchronization connections as describedin 8.1, “Synchronization connections”, remem-bering to terminate the slave unit.2 Connect the DIGITAL I/O u of the master unit(source) to the TDIF-1 (DIGITAL I/O) of the slave(target).Use only approved cables (PW-88D or PW-88DL) to connect the DTRS units. Use of anyother cables can cause damage to the units andwill invalidate the warranties.3 Turn on both units. Make sure the machines’IDs are correctly set (8.2.2, “Setting machineID”).4 Insert the master tape into the source masterand a blank tape, formatted with the samesampling frequency and bit resolution as themaster tape, into the target slave.5 Select the digital inputs on the target slave (thisdiffers between models—for the DA-98HR, see6.3.3, “Selecting input sources”).6 Put the target slave machine into CHASE mode(8.2.3, “Master/slave settings (CHASEmode)”).7 Locate the master tape to a point before thematerial you want to duplicate. The targetslave also locates since it is in CHASE mode.8 Arm all tracks (REC FUNCTION) on the targetslave machine and make sure that all RECFUNCTION switches on the source master areturned OFF (press the ALL SAFE key to makesure).NOTEIf any REC FUNCTION switches on the source masterare turned on, you will erase your master tape! You maywant to use the tape’s write-protect tab to prevent any suchaccidents.9 On the master machine, hold down RECORDand press PLAY.No recording will take place on the source mas-ter, but the tracks will be recorded digitally ona one-to-one basis to the target slave.There is no need to carry out any special pre-dubbing procedure such as timing the digitaloutput, as the digital and analog outputs areseparate.You can use the Track Copy (DA-38, DA-98) orthe input patchbay functions (DA-98HR orDA-78HR) on the target slave machine totransfer tracks from the source master tape todifferent tracks on the target slave. Note, how-ever, that you cannot combine tracks by thismethod.8.5.1 Synchronized formattingWhen several DTRS units are connected together,you can format several tapes simultaneously, usingone machine as the master. This can be a very conve-nient way of saving time and effort.1 Make sure that all machines have their IDs set,that they are connected together using theSYNC connections, as described above, andthat the last unit in the chain is terminated.SOURCEMASTERTARGETSLAVEPW-88D or PW-88DL(digital I/O cable)PW-88S(sync cable)Terminatorplug
