Section 10 – Operations related to timecode06/97 – 1.00 – 10-11the CHASE key is pressed. You must determinewhether the chase mode refers to timecode or tothe DTRS sync, and this is done using the TimeMode menu (see 10.1.3, “Selecting TC or ABStiming”). If ABS is selected, when CHASE ispressed, the machine will enter DTRS sync mode,but if TC is selected, the machine will attempt tolock to external timecode.When the DA-98 is in “chase-ready” mode (theCHASE indicator is flashing) and timecode isreceived at the TIME CODE IN connector, the DA-98 will start to chase the timecode. When it islocked to the incoming timecode, the CHASE indi-cator will light steadily.The exact ways in which it chases the timecodeand handles transport functions, etc.are deter-mined by a number of settings, as describedbelow:10.7.2 Setting timecode offsetYou may enter a timecode offset for the audiofrom the DA-98 to match the audio (or videosequence) from the timecode master.As with the machine offset (see 9.3.1, “Settingmachine offset”), you can either set this manually,entering the numbers, or set it “on-the-fly” by ear.In either case, once the offset has been entered, itcan then be edited.The offset can be set to subframe accuracy (100subframes = 1 frame).10.7.3 Setting timecode offset from themenu1) Go to menu group 4, move the cursor to TCOffset and press ENTER:2) Use the LEFT and RIGHT keys to select the field(hours, minutes, seconds, frames or subframes)and use the UP and DOWN keys to set the value.You can use the function keys in the number keymode (see 5.2.2, “Using the function keys as num-ber keys”) to enter the offset (and the leading sign)directly.If this value is set to anything other than00:00:00:00.00, the OFFSET indicator by the tapecounter will light.If you move the cursor to the right digit of the sub-frame field, this will act as a “roll-over” field (i.e.if you are incrementing the value and it passes 99,the frame field will increment.10.7.4 Cancelling timecode offsetWhen the timecode offset value is set to all zeros,timecode offset is cancelled and the OFFSET indi-cator goes out.1) From the Timecode Offset menudescribed above, press the UP and DOWN keyssimultaneously to reset the value.10.7.5 Setting timecode offset on-the-flyThere is a second “invisible field” to the right ofthe subframe field (similar to that for machine off-set settings – (page 9-3)). Moving the cursor tothis field changes the display:This screen allows you to set the offset by press-ing the UP or the DOWN key. When you do this,the difference between incoming timecode and theNOTES• The timecode frame rate used on the DA-98 must matchthe frame rate of incoming timecode (see 10.3, “Select-ing the frame rate”). If they do not match, a warningmessage will be shown, and the DA-98 will not chase totimecode. You can check the frame rate of incomingtimecode (see 10.5.7, “Checking external timecode”)and of the timecode recorded on the DA-98’s tape (see10.2.5, “Checking tape TC”• The timecode used internally by the DA-98 does nothave to be an actual timecode striped tape. Instead,timecode can by “synthesized” from the ABS subcodetimings, as described in 10.2, “Tape timecode mode”.T i m e c o d e O f f s e t+ 0 0 : 0 0 : 0 0 : 0 0 . 0 0 2 5 FT i m e c o d e O f f s e tA U T O O F F S E T
