3) Transfer the value from the LOCATE TIME/
VALUE display to the LCD display by holding
down the SHIFT key and pressing the ENTER/
LOAD key.
If you need to “fine-tune” this value, you can use
the
UP and DOWN keys to adjust the value of the
offset while monitoring the playback of the units.
8.1.10 Auto Timecode Offset function
In addition to the manual offset entry, it is also
possible to set a timecode offset automatically by
following the procedure below:
1) From menu group 4, move the cursor to TC
Offset and press SELECT .
2) Use the RIGHT key to move the cursor to a
second “invisible” field to the right of the
frames field. The display will appear as follows:
3) Locate the two tapes (master and slave) so that
they have the right offset.
You can play up the tapes and pause them once
they have been lined up, or carry out the next step
while either or both of the tapes is being replayed.
4) Press either the UP or DOWN key at the
correct offset time to capture and store the
offset.
8.1.11 Independent clock settings
It is sometimes useful to be able to reference
different clock timings for the different DTRS
units in the chain (if one unit is recording digital
input from another digital source and another is
referenced to video, for example).
To allow independent settings (this function is
only available if the time mode is set to timecode,
and the DA-98 is acting as a slave):
1) From menu group A, move the cursor to
ClkMode (clock mode), and press SELECT :
2) Use the UP and DOWN keys to select between
automatic ( Auto ) and individually-selectable
( Indv ) clock settings.
In the example above, the first three DTRS units
have their clocks set automatically according to the
first clock setting (i.e. units 2 and 3 cannot have
their clocks set using the function described in
7.2.6, “Clock selection”), and the fourth unit can
have its clock set independently of the other three.
8.2 Advanced timecode
functions
The following functions are designed to extend
the capabilities of the DTRS system under various
circumstances when working with timecode-based
setups. These functions are described more fully
in the DTRS manuals. Refer to the appropriate
sections of these manuals for further information,
if required.
8.2.1 Timecode output source
The DA-98 is able to output timecode from a
variety of sources.
NOTE
If you are using a DA-98 with ABS timing used to
synthesize timecode, the DA-98 allows you to set an ABS
offset, which may be used in place of this function (see
8.1.2, “Synthesizing timecode from ABS times” and also
10.2.3 of the DA-98 manual.
NOTE
There is an “invisible” field immediately to the right of the
frames field. If you place the cursor there and increment or
decremennt the value, you can change the time as a whole
(as the frames field passes its maximum value, the seconds
field will increment).

NOTE
In a system with multiple digital audio devices, the same
clock should be used by all units which are to perform digi-
tal audio transfer (e.g. dubbing, etc.). If units have different
reference clocks, you cannot transfer digital audio between
them.
