Section 8.2 - Advanced timecode functions
8-7
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:
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 t he
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
The 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
05 Frame, Leap and off.
8.2.7 MIDI 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.
However, 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 becaus e 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 man ual.
1) From menu group 7, move the cursor to MTC
Out, and press SELECT:
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.
8.2.8 Park position
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 D A -9 8 m anu a l fo r fu rth e r
details of this function.
