outputs, whichever set of outputs is in use at the 
time.
1) Go to menu group 5, move the cursor to 
OutTc Tmg (output timecode timing) and 
press 
ENTER:
2) Use the 
UP and DOWN keys to select between 
Analog and Digital.
10.4.5 Using MIDI Time Code (MTC)
The DA-98 can output MIDI Time Code in almost 
exactly the same way as it outputs audio timecode, 
with the following exceptions.
MIDI Time Code can be output either when the 
DA-98 is...

2) Select timecode as the timing reference (see 
10.1.3, “Selecting TC or ABS timing”).
3) Select a frame rate (see 10.3, “Selecting the 
frame rate”).
4) From menu group 8, move the cursor to 
TcRec Src(source for timecode recording) 
and press 
ENTER:
5) Use the 
UP and DOWN keys to select the source 
of the timecode as 
Generator TC. 
The options here are External TC (received 
at 
TIME CODE IN), Generator TC (the 
internal generator) or...

If there is no timecode source, the tape counter 
will show all hyphens while the timecode track is 
armed.
After starting the generator, you may want to 
make other settings, and will therefore have to 
change the display screen.
The tape counter shows the timecode from the 
generator, but you can use the following proce-
dure to check the frame rate, especially in situa-
tions where you are using the output from the DA-
98’s generator to...

together, keeping a strict relationship between the 
audio and timecode tracks.
In all other cases, we suggest using either the DA-
98’s internal generator or timecode from tape. If 
you use these as sources, there will be no jitter 
problems, and any problems of synchronization 
with the digital audio clock are eliminated.
When recording timecode from a timecode 
generator, make sure that there is a common 
video reference for both the...

flash.
If the timecode source is not clock-synchronized 
with the DA-98, a warning will be shown on the 
display screen. In this case, although you can 
record timecode, it is not recommended, as this 
will probably cause problems later on.
5) Stop the external timecode source, and rewind 
or reset it to a point prior to where you want 
recording to begin. 
The tape counter will now start to...

the CHASE key is pressed. You must determine 
whether the chase mode refers to timecode or to 
the DTRS sync, and this is done using the Time 
Mode menu (see 10.1.3, “Selecting TC or ABS 
timing”). If 
ABS is selected, when CHASE is 
pressed, the machine will enter DTRS sync mode, 
but if 
TC is selected, the machine will attempt to 
lock to external timecode.
When the DA-98 is in “chase-ready” mode (the 
CHASE indicator is flashing) and...

internal timecode will be captured and stored as 
the timecode offset (either a positive or negative 
value).
Note that if the words 
AUTO OFFSET are 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...

the slave is now 10 minutes and 4 frames behind 
the master.
Since the slave is meant to be exactly 10 minutes 
behind the master, the difference, +4 frames, is the 
“relative difference” between the master and the 
slave.
To view the absolute and relative differences 
between master and slave machines:
1) Go to group menu E:
2) Move the cursor to either 
Abs Diff 
(absolute difference) or 
Rel Diff (relative 
difference). The appropriate...

10.7.11Individual recording while chasing 
timecode
If slave DTRS units are chasing a master DTRS 
unit, the default action is for the slaves’ record sta-
tus to follow that of the master. If the slaves are 
connected with TC as well as SYNC, and have TC 
rather than ABS selected as the timing reference, 
this default behavior can be overridden using the 
function described here.
1) Go to menu group 4, move the cursor to 
TcChs Rec...

11 – External control
The DA-98 can be controlled by other units, either 
through the 
REMOTE IN/SYNC IN TASCAM con-
nector [43] as described in 9, “Synchronization 
with other DTRS units”, the 9-pin 
RS-422 serial 
control connector [40], or through the 
MIDI IN con-
nector [41] using MIDI Machine Control.

Ctrl Prt (control protocol) and press 
ENTER:
