Kolpak DA-98 Park position, Automatic park position setting, Absolute and relative difference

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 AUTOOFFSETare not 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 ParkoptimumrPosikpre-Porollsposiitioniofornthe DA-98 (when it is timec de slave) to park itself relative to the m sterTESTtimecode device so that it will lock up and st rt playingoffquickly. 02s08f25F

1) Go to menu gr up 4, move the cursor to (park position) and press ENTER:

2)The time value shows the current park setting, and this can be changed using the UP and DOWN keys, or the function keys.

10.7.7Automatic 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.

1) ParkGo toTESmenuroffPosikTPogr upsi4,t0movei2osn0the8fcursor25Fto (park position) and press ENTER:

2)Play and stop the master tape.

3)Turn the DA-98’s CHASE on, if it is off.

4)Use the UP or DOWN keys to turn the TEST parameter on.

The DA-98 will then rewind so that the relative difference is zero. When the DA-98 has stopped, go on to the next step below.

5) Play the timecode master.

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

6)Turn TESToff (UP or DOWN key). The optimum park pre-roll time for the timecode master is now stored.

10.7.8Absolute and relative difference

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

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:

Master 10:15:12:12

Slave 10:05:12:08

10-12 – 1.00 – 06/97
