Park Position; Automatic Park Position Setting; Absolute And Relative Difference - Tascam DA-98 Owner's Manual

Section 10 – Operations related to timecode
internal timecode will be captured and stored as
the timecode offset (either a positive or negative
value).
Note that if the words
displayed on the screen, you cannot capture the
offset value.
Once the offset value has been captured success-
fully, the display will change to show the captured
offset value on the bottom line.
After the timecode offset has been entered in this
way, you can "fine-tune" the value to subframe
accuracy using the method described above.

10.7.6 Park position

When the DA-98 is slaved to an external timecode
source, it will take some time between the master
unit starting to play and starting to transmit time-
code for the DA-98 to read.
These functions allow you to measure and test the
optimum pre-roll position for the DA-98 (when it
is a timecode slave) to park itself relative to the
master timecode device so that it will lock up and
start playing quickly.
1) Go to menu group 4, move the cursor to
(park position) and press
2) The time value shows the current park setting,
and this can be changed using the
keys, or the function keys.

10.7.7 Automatic park position setting

When the DA-98 is acting as a timecode slave, it
can automatically determine the optimum park
pre-roll position to sync with the master.

2) Play and stop the master tape.
3) Turn the DA-98's

5) Play the timecode master.

10.7.8 Absolute and relative difference

:
ENTER
The offset as set above (10.7.2, "Setting timecode
offset") can be called the "absolute difference"
between the two times. However, if the slave
machine "wanders" (actually, this is unlikely), the
offset (theoretical difference) will not be equal to
the absolute difference. The "relative difference"
is expressed as below:
Relative difference = Absolute difference – Offset
and
UP
Thus, if the offset is set on a slave machine to
+00:10:00:00 (10 minutes) and while chasing, the
two machines' counters read as follows:

The DA-98 will then rewind so that the relative
difference is zero. When the DA-98 has stopped,

When the value shown on screen has stopped
changing and is stabilized, go on to the next step
