Section 8.2 - Advanced timecode functions

When the DA-98 is chasing timecode, it can be set to lock to timecode once and run freely, or it can constantly monitor the timecode, and issue “speed-up” and “slow-down” messages to its transport to stay in sync. However, if an external or video clock is used as the clock source, the playback output will be muted while the DA-98 is adjusting the speed. If you select the rechase mode (which you may wish to do if there are gaps in the timecode), you can select a “window”. Only if the difference between the received timecode and the DA-98 position falls outside this window, the DA- 98 will rechase. However, the DA-98’s timekeep- ing is almost always good enough for you not to need to rechase. See 10.7.9 of the DA-98 manual for further details of this facility.

1) From menu group 4, move the cursor to RechsMode and press SELECT:

R e c h a s e M o d e

2)Use the UP and DOWN keys to select either rechase or free as the mode, as explained above.

3)If you have selected rechase, move the cursor to the Window field, and select either 1 or 2 seconds and the window period.

This setting has no effect if free has been selected as the mode.

8.2.6 Fast LTC

98The DA-98 allows you to select three modes in which linear timecode (LTC) will be output when the unit is in a fast transport mode (forward or rewind).

Firstly, there is a 5 frame option in which five con- secutive frames are output, the tape is then read again, and five further consecutive frames are out- put, starting at the frame which has just been read. Secondly, you can choose a “leap” option, in which timecode is continuously output, but not consecutively (the values between frames will leap as the tape is read). The last mode is “off”, in which case, no timecode will be output in fast transport modes. See section 10.4.3 of the DA-98 manual for further details of this facility.

1)From menu group 5, move the cursor to Fast LTC and press SELECT:

2) Use the UP and DOWN keys to select between

05Frame, Leap and off.

8.2.7MIDI Timecode output

Both the DA-88 and DA-98 output MIDI Time- code (MTC) from their MIDI OUT jacks, which echoes the linear timecode output from the time- code outputs.

98However, the DA-98 allows you to choose under what circumstances MTC will be output. You can choose not to output MTC at all, to output while fast winding as well as during placyback and recording, or to output MTC while the tape is stopped (this is possible because MTC is indi- rectly derived from an off-tape signal). For further details of this facility, see section 10.4.5 of the DA-98 manual.

1)From menu group 7, move the cursor to MTC Out, and press SELECT:

M T C O u t p u t

2)Use the LEFT and RIGHT cursor keys to select the field to be set, and select on or off using the UP and DOWN keys.

NOTE

If the Output field is set to off, neither of the other settings will have any effect.

8.2.8 Park position

9888 The park position allows you to set a pre- roll position automatically on a DA-98 slaved to a master timecode source. This gives the master unit time to start playing timecode after starting to play, and provides optimal lock-up when locating and chasing external timecode. See sections 10.7.6 and 10.7.7 of the DA-98 manual for further details of this function.
