9 – Operations related to timecode–Recording timecode58 TASCAM DA-98HR1 Use the Ó and Á keys to select the “hours”field.2 Use the § and ¶ keys to set the “hours” value.Here we assume (for simplicity) that the “hours”value has been set to 00. If you set this to a differentvalue, add the appropriate offset as you read thisexplanation.Timecode is synthesized, starting at 00 57 00 00,allowing three minutes of timecode “pre-roll” beforethe nominal start of the piece at 01 00 00 00.With ABS-13 selected, once the tape is posi-tioned approximately 13 minutes from the start, thetimecode restarts at 01 57 00 00. If ABS-23has been selected, this occurs approximately 23 min-utes after the start of the tape (the piece is 20 minuteslong). This allows another track to begin at 02 0000 00.This process continues until the end of the tape isreached. Wherever the tape is located, this calcula-tion is performed, allowing you to locate each trackeasily with reference to the timecode values.The diagram below shows the relationship betweenthe “synthesized” timecode and the absolute time ontape, assuming that the “hours” value has been set to00.9.2.5 Checking tape TCThe TAPE TC indicator by the tape counter lightswhen either timecode recorded on tape or synthe-sized from ABS is being read.As well as the tape counter, the display screen canalso be used to show tape timecode values and theframe rate currently recorded on tape, as describedbelow.1 Go to menu group E, and move the cursor toTape TC:2 Start playing the tape.3 The tape timecode value is displayed on thebottom line, together with the system framerate.If TC Track has been selected, but thetimecode which has been recorded on the tapediffers from the system frame rate, the framerate at the lower right of the screen will be pre-ceded by an asterisk (*).9.3 Recording timecodeThis section refers to the process of actually stripingthe timecode track with timecode.9.3.1 Selecting the timecode sourceThe DA-98HR allows you to select one of threesources for recording timecode: the DA-98HR’sinternal generator, an external source, or timecodebased on the “Tape TC” source.To select the source for recording timecode:1 Go to menu group 8, move the cursor toTcRec Src (source for timecode record-ing), and press ENTER:2 Use the § and ¶ keys to select a source for thetimecode recording from the following options:Generator TC, Tape andExternal TC.If you select Tape, the source of the tapetimecode is also shown, as determined in thetape timecode selection menu (9.2, “Tape time-code mode”).NOTEGenerally speaking, timecode should be recorded from anexternal source only when audio tracks and timecode mustbe transferred together from external units.
