The frame rate displayed depends on the timecode

frame rate as recorded on the tape (if

has been selected) or on the selected
frame rate (if another option has been chosen).
10.3 Selecting the frame rate
The DA-98 can use the following standards for
timecode (including timecode synthesized by the
ABS to TC facility): 30 non-drop, 30 drop, 29.97
non-drop, 29.97 drop, 25, and 24 frames per sec-
ond (fps).

non-drop, 29.97 drop, 25, and 24 frames per sec-
ond (fps).
When using the DA-98 to chase to a timecode
master, the system frame rate on the DA-98 must
match the frame rate of the timecode master, oth-
erwise chase operations are not possible.
master, the system frame rate on the DA-98 must
match the frame rate of the timecode master, oth-
erwise chase operations are not possible.
The frame rate is automatically set when a tape
which has been striped with timecode is inserted,
or if power is switched on with a striped tape
already inserted in the unit. The frame rate
recorded on the tape will be used as the system
frame rate.

10.3.1 Pull up and pull down (Fs shift)
When working in film post-production with
NTSC telecine equipment, the frame rate of film
(24 fps) and the NTSC color frame rate (29.97) do
not form a simple mathematical ratio, and the
sampling frequencies of either 44.1kHz and
48kHz are therefore affected on transfer back to
film.

To avoid this, pull up and pull down functions are

10.4 Timecode input and
output
Only timecode (not ABS timing) can be transmit-
ted and received via the
ted and received via the
TIME CODE IN
and
OUT
jacks. ABS timings are used for multiple DTRS
unit synchronization.
unit synchronization.
10.4.1 Timecode input
There are two primary reasons for the DA-98 to
receive timecode: when the DA-98 is chasing to
timecode, and must receive the master timecode,
and when the DA-98 is to record timecode from
another unit (but see 10.5.5, “External timecode
sources” below).
