9 – Operations related to timecode–Recording timecodeTASCAM DA-98HR 61In all other cases, we suggest using either the DA-98HR’s internal generator or timecode from tape. Ifyou use these as sources, there will be no jitter prob-lems, and any problems of synchronization with thedigital audio clock are eliminatedNOTEWhen recording timecode from an external digital source, make sure the digital clock of the DA-98HR and that of the external source are synchronized, as explained in ?????????? and ??????????. A warning message will appear if the timecodesource and the DA-98HR are not synchronized, but timecode can still be recorded. However, the resulting timecode recording will probably cause synchronization problems in the future.When recording timecode from a timecode generator,ensure there is a common video reference for both the DA-98HR and the generator (set the CLOCK of the DA-98HRto VIDEO).When recording timecode from another DTRS unit,synchronize the two units using ABS chase (setting thetimecode/audio source unit to be a slave unit as describedin 8, “DTRS synchronization”). After the two units havebeen synchronized in this way, timecode and audio can betransferred together.When recording timecode from a digital source (audioor video), make sure that the DA-98HR and the other unitare locked to a common word (audio recorder) or video(video recorder) clock reference. After the two machineshave been synchronized in this way, timecode and audiocan be transferred together.9.3.6 Recording timecode from ananalog recorderWhen recording timecode from an analog recorder,feed the analog recorder or its external synchronizerand the DA-98HR with a common video source, anduse the video resolve function of the analog recorderor synchronizer, if this is provided.If the analog recorder has no video resolve function,it may have a timecode chase function, which can bedriven by any timecode source from the followinglist:• timecode already recorded on an audio track of theDA-98HR• timecode recorded on other DTRS units, usingABS chase with the DA-98HR• timecode recorded on any other recorders synchro-nized with the DA-98HR• a timecode generator, video-synchronized with theDA-98HR.NOTEDo not use any timecode recorded on the DA-98HR’s dedi-cated subcode track as the timecode master when transfer-ring timecode from an analog recorder.If your analog recorder cannot chase to external time-code, you must first record the timecode from theanalog recorder on an audio track of the DA-98HRand then transfer the timecode to the dedicated time-code track.Timecode recorded on the audio track in this way issynchronized to the audio clock, and can subse-quently be transferred (through patching) to the time-code track.9.3.7 Recording timecode fromexternal sources1 Set the Time Mode to TC (9.1.3, “Select-ing TC or ABS timing”).2 Select the appropriate frame rate (9.4, “Select-ing the frame rate”) which matches the incom-ing timecode.3 Set the timecode record source toExternal TC (9.3.1, “Selecting thetimecode source”).4 Press the TC REC key to arm the timecodetrack.5 Start the external source to check the status ofthe external timecode.If no external timecode has been received since theDA-98HR has been switched on, the tape counterwill show all hyphens. (-- -- -- --).If external timecode has been received since the DA-98HR has been switched on, but is not currentlybeing received, the tape counter will flash.If the external timecode is currently being received atnormal (play) speed, the tape counter will show thevalue of the timecode currently being received. If theexternal timecode is being received from a source infast wind mode, the tape counter will flash.If the timecode source is not clock-synchronizedwith the DA-98HR, a warning will be shown on thedisplay screen. In this case, although you can recordtimecode, it is not recommended, as this will proba-bly cause problems later on.6 Stop the external timecode source, and rewindor reset it to a point prior to where you wantrecording to begin. The tape counter nowstarts to flash.7 Restart the source. The tape counter displaysthe received timecode.8 Press and hold down RECORD and press PLAY.Timecode is recorded from the external sourceonto the timecode track.If the tape counter was flashing when the TCREC indicator was flashing (the timecode trackwas armed), the tape counter now shows allhyphens, and nothing will be recorded (but any
