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 playing, or in fast forward or rewind, or 
when stopped. You can turn off the output during 
the “fast” modes and while stopped, to avoid over-
loading a MIDI data stream.
1) Go to menu group 7, move the cursor to MTC 
Out and press 
ENTER:
2) Use the 
LEFT and RIGHT cursor keys to select 
the field for which you want to turn MTC on 
and off, and the 
UP and DOWN keys to turn 
MTC on or off.
Note that if the Output field is turned off, 
turning the other fields 
on will have no effect.
10.5 Recording timecode
10.5.1 Selecting the timecode source
The DA-98 allows you to select one of three 
sources for recording timecode: the DA-98’s inter-
nal generator, an external source or timecode 
based on tape.
To select the source for recording timecode:1) Go to menu group 8, move the cursor to 
TcRec Src (source for timecode recording), 
and press 
ENTER:
2) Use the 
UP and DOWN keys to select a source 
for the timecode recording from the following 
options: 
Generator TC, Tape and 
External TC.
If you select Tape, the source of the tape time-
code will also be shown, as determined in the tape 
timecode selection menu (see 10.2, “Tape time-
code mode”).
If you are recording timecode only, we suggest 
that you do not use external sources for recording 
timecode.
Set 
Tape as the source as described immediately 
above, and use 
ABS or ABS-Ofs (see 10.2.2, 
“ABS setting” and 10.2.3, “ABS-Ofs setting”) as 
tape timecode sources. This will ensure an accu-
rate relationship between the timecode and the 
ABS timing reference (the fact that the generator 
must be started manually means that there will not 
be a tight relation between timecode and the ABS 
timing).
This will also allow you to synchronize multiple 
DTRS units accurately to external timecode, even 
though the slave units are not timecode-based.
10.5.2 Recording timecode using the 
generator
1) Insert a formatted tape into the DA-98.
It is possible to format and stripe a new tape simul-
taneously, by setting up the formatting procedure 
as described in 6.1, “Formatting a tape” and then 
following the instructions below.
Output TC Timing

MTC Output

NOTE
Generally speaking, timecode should be recorded from 
an external source only when audio tracks and timecode 
must be transferred together from external units. In all 
other cases, we suggest that you use the internal genera-
tor or the tape as sources for recording timecode. 
						

							Section 10 – Operations related to timecode
06/97 – 1.00 – 10-7
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 the third option, which 
reflects the settings made in the 
Tape TC
Mode
 menu (see 10.2, “Tape timecode mode”).
6) Go to menu group 8, move the cursor to Gen
Start
 (generator start time) and press 
ENTER:
7) Use the 
LEFT and RIGHT keys to select the field 
(hours, minutes, seconds or frames) to be 
edited, and the 
UP and DOWN keys to change 
the value. 
You can also use the function keys as number keys 
to input the value directly, as described in 5.2.2, 
“Using the function keys as number keys”.
8) When you have finished setting the start time, 
press 
ENTER.9) Go to menu group 8, move the cursor to 
Gen
Mode
 (generator mode) and press ENTER:
10) Press the 
TC REC switch [31]. 
The indicator will start flashing.
11) Now press the UP or DOWN key to start the 
timecode generator.
The TC GEN indicator by the tape counter will 
light.
12) Press and hold the PLAY and press the RECORD 
key and the tape will start recording.
The TC REC indicator will light steadily.
The display will change from 
Stop to Run. 
Pressing the 
UP or DOWN key while the cursor is 
under this field will stop the generator.
You can also start recording and then start the 
timecode generator. In this case, an warning mes-
sage will appear on the display screen as you start 
recording, to tell you that there is no timecode 
source.
If the 
Mode field is set to Continue rather 
than 
Reset, stopping the generator and then re-
starting it will pick up the timecode values from 
where it left off.
Conversely, setting this field to 
Reset will 
restart from the start time set above every time the 
generator is stopped and re-started.
It is also possible to “drop into” timecode record-
ing by starting the transport in record mode and 
then pressing the 
TC REC switch. However, we do 
not recommend this method of working, as it is 
impossible to check the timecode source prior to 
recording.
If the method described above (arming the time-
code track, and then starting recording) is used, 
the tape counter is used to show the output from 
the timecode source (the generator) when the 
timecode track is armed, flashing when the tape is 
stopped, and steady when the tape is running.

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 stripe another tape, etc.
1) Go to menu group E, and move the cursor to 
Gen TC:
2) The bottom line of the display screen will show 
the timecode values currently being output by 
the generator.
10.5.3 Synthesizing timecode from ABS 
timing
When you are synthesizing timecode from ABS, 
using any of the following options: 
ABS, ABS-
Ofs
, ABS-13 or ABS-23, as described in 
10.2, “Tape timecode mode”, the tape counter dis-
play behaves differently from the way as 
described above. 
The tape counter will not flash when the timecode 
track is armed and the tape is stopped, and it will 
not display all hyphens, since the timecode source 
is always available.
In this case, you can start recording the timecode 
at any time (before or after) the tape has started 
moving.
10.5.4 Assembling timecode
You may want to use the assembly function when 
the first part of a tape contains timecode, and you 
want to stripe the rest of the tape with timecode 
that follows on seamlessly from the originally 
recorded timecode. The assembly function reads a few seconds of 
timecode from tape and then uses this to jamsync 
the internal generator, which then stripes the rest 
of the tape.
1) Select 
TC Track from the Tape TC Mode 
menu (see 10.2.1, “TcTrack setting”).
2) Go to menu group 8, move the cursor to 
TcRec Src (timecode record source) and 
press 
ENTER:
3) Make sure the tape is rewound to a point which 
already contains timecode which can be used as 
the source for the rest of the tape.
4) Arm the timecode track (press 
TC REC so that 
the indicator is flashing).
The tape counter will show the last timecode read 
from tape as a flashing display.
5) Start playing the tape.
As timecode is read from the tape, the tape counter 
will show the values read from tape. If the tape 
does not contain timecode, the tape counter will 
show all hyphens.
6) Start recording when the tape counter is 
showing timecode (press the 
RECORD key).
The TC REC indicator will light steadily
Timecode will now be laid down in a continuous 
stream, starting at the current timecode value. The 
tape counter will display continuous timecode 
values.
It is also possible to press the 
TC REC key after 
starting audio recording.
10.5.5 External timecode sources
The following notes should help you when you 
must record timecode on the DA-98 from an 
external source (analog or digital). As mentioned 
earlier, though, you should only need to record 
timecode from an external source when the audio 
and timecode tracks have to be transferred

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 DA-98 and the gener-
ator (set the 
CLOCK of the DA-98 to VIDEO).
When recording timecode from another DTRS 
unit, synchronize the two units using ABS chase 
(setting the timecode/audio source unit to be a 
slave unit as described in 9.2.3, “Master/slave set-
tings (CHASE mode)”). After the two units have 
been synchronized in this way, timecode and 
audio can be transferred together.
When recording timecode from a digital source 
(audio or video), make sure that the DA-98 and 
the other unit are locked to a common word (audio 
recorder) or video (video recorder) clock refer-
ence. After the two machines have been synchro-
nized in this way, timecode and audio can be 
transferred together.
When recording timecode from an analog 
recorder, feed the analog recorder or its external 
synchronizer and the DA-98 with a common video 
source, and use the video resolve function of the 
analog recorder or synchronizer, if this is 
provided. 
If the analog recorder has no video resolve func-
tion, it may have a timecode chase function, which 
can be driven by any timecode source from the 
following list: • timecode already recorded on an audio track of 
the DA-98 
• timecode recorded on other DTRS units, using 
ABS chase with the DA-98
• timecode recorded on any other recorders syn-
chronized with the DA-98
• a timecode generator, video-synchronized with 
the DA-98.
If your analog recorder cannot chase to external 
timecode, you must first record the timecode from 
the analog recorder on an audio track of the DA-
98 and then transfer the timecode to the dedicated 
timecode track.
Timecode recorded on the audio track in this way 
is synchronized to the audio clock, and can subse-
quently be transferred (through patching) to the 
timecode track.
10.5.6 Recording timecode from external 
sources
1) Set the Time Mode to TC (see 10.1.3, 
“Selecting TC or ABS timing”).
2) Set the timecode record source to 
External
TC
 (see 10.5.1, “Selecting the timecode 
source”).
3) Press the 
TC REC switch to arm the timecode 
track.
4) Start the external source to check the status of 
the external timecode.
If no external timecode has been received since the 
DA-98 has been switched on, the tape counter will 
show all hyphens. 
If external timecode has been received since the 
DA-98 has been switched on, but is not currently 
being received, the tape counter will flash.
If the external timecode is currently being received 
at normal (play) speed, the tape counter will show 
the value of the timecode currently being received. 
If the external timecode is being received from a  NOTE
When recording timecode from an external digital 
source, make sure the digital clock of the DA-98 and 
that of the external source are synchronized, as 
explained in 4.2.3, “Word clock connections” and 4.2.2, 
“Video connections”. A warning message will appear if 
the timecode source and the DA-98 are not synchro-
nized, but timecode can still be recorded. However, the 
resulting timecode recording will probably cause syn-
chronization problems in the future.
NOTE
Do not use any timecode recorded on the DA-98’s dedi-
cated subcode track as the timecode master when trans-
ferring timecode from an analog recorder. 
						

							Section 10 – Operations related to timecode  
10-10 – 1.00 – 06/97source in fast wind mode, the tape counter will 
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 flash.
6) Restart the source.
The tape counter will display received timecode.
7) Press and hold down PLAY and press RECORD. 
Timecode will now be recorded from the 
external source onto the timecode track.
If the tape counter was flashing when the TC REC 
indicator was flashing (the timecode track was 
armed), the tape counter will now show all 
hyphens, and nothing will be recorded.
10.5.7 Checking external timecode
There is another way you can check external time-
code, as described below. This method is useful 
for checking the frame rate of incoming timecode, 
if you are not sure what frame rate has been 
recorded or is being generated by the timecode 
source.
1) Go to menu group E, and move the cursor to 
Ext TC:
2) Incoming timecode will be displayed on the 
bottom line, together with the frame rate of the 
timecode.
10.6 Video resolution
As explained above, if the DA-98 is to be synchro-
nized with a VTR, all units must share a common 
video reference for the digital audio clocks, gener-
ated either by the VTR or from a sync generator.As well as the sample clock, the timecode can be 
referenced to a video clock (i.e. the start of each 
timecode frame is synchronized with each frame 
boundary received at the 
VIDEO IN terminal) or 
can be independent of the received frame clock.
Additionally, in a similar way to timecode rechase 
mode (page 10-13), the DA-98 can be set to 
rechase the video frame sync (muting playback 
output as it rechases), or to run freely once sync is 
achieved, ignoring any breaks in the received 
video signal.
1) Go to menu group 5, move the cursor to 
Vid
Rslv
 (Video Resolve) and press ENTER:
2) Use the 
LEFT and RIGHT keys to select the 
frame synchronization mode (
on/off) and 
the 
UP and DOWN keys to toggle it on and off.
3) Use the 
LEFT and RIGHT keys to select the video 
rechase mode (either 
free or re-sync).
10.7 Chasing to timecode
The following sections describe the operation of 
the DA-98 when chasing to external timecode.
The operation of the 
CHASE switch is similar to 
the way the 
CHASE switch is used when synchro-
nizing DTRS units (see 9.2.3, “Master/slave set-
tings (CHASE mode)”), but in this case, the 
machine ID is not used.
10.7.1 Machine ID and timecode
Since a DA-98 with machine ID set to 1 is always 
a master unit as regards DTRS sync operation, 
there is no need to make any setting on such a 
machine if it is to be a timecode slave. As long as 
timecode is received at the 
TIME CODE IN connec-
tor [37] (the 
EXT TC indicator is lit), a unit whose 
machine ID is set to 1 will automatically enter 
timecode chase mode when the 
CHASE key is 
pressed.
However, when a DA-98 unit has its machine ID 
set to a value other than 1, there is a conflict when

							Section 10 – Operations related to timecode
06/97 – 1.00 – 10-11
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 timecode is 
received at the 
TIME CODE IN connector, the DA-
98 will start to chase the timecode. When it is 
locked to the incoming timecode, the 
CHASE indi-
cator will light steadily.
The exact ways in which it chases the timecode 
and handles transport functions, etc.are deter-
mined by a number of settings, as described 
below:
10.7.2 Setting timecode offset
You may enter a timecode offset for the audio 
from the DA-98 to match the audio (or video 
sequence) from the timecode master.
As with the machine offset (see 9.3.1, “Setting 
machine offset”), you can either set this manually, 
entering the numbers, or set it “on-the-fly” by ear. 
In either case, once the offset has been entered, it 
can then be edited.
The offset can be set to subframe accuracy (100 
subframes = 1 frame).
10.7.3 Setting timecode offset from the 
menu
1) Go to menu group 4, move the cursor to TC
Offset
 and press ENTER:
2) Use the 
LEFT and RIGHT keys to select the field 
(hours, minutes, seconds, frames or subframes) 
and use the 
UP and DOWN keys to set the value.
You can use the function keys in the number key 
mode (see 5.2.2, “Using the function keys as num-
ber keys”) to enter the offset (and the leading sign) 
directly.
If this value is set to anything other than 
00:00:00:00.00, the 
OFFSET indicator by the tape 
counter will light.
If you move the cursor to the right digit of the sub-
frame field, this will act as a “roll-over” field (i.e. 
if you are incrementing the value and it passes 99, 
the frame field will increment.
10.7.4 Cancelling timecode offset
When the timecode offset value is set to all zeros, 
timecode offset is cancelled and the 
OFFSET indi-
cator goes out.
1) From the 
Timecode Offset menu 
described above, press the 
UP and DOWN keys 
simultaneously to reset the value.
10.7.5 Setting timecode offset on-the-fly
There is a second “invisible field” to the right of 
the subframe field (similar to that for machine off-
set settings – (page 9-3)). Moving the cursor to 
this field changes the display:
This screen allows you to set the offset by press-
ing the
 UP or the DOWN key. When you do this, 
the difference between incoming timecode and the 
NOTES
• The timecode frame rate used on the DA-98 must match 
the frame rate of incoming timecode (see 10.3, “Select-
ing the frame rate”). If they do not match, a warning 
message will be shown, and the DA-98 will not chase to 
timecode. You can check the frame rate of incoming 
timecode (see 10.5.7, “Checking external timecode”) 
and of the timecode recorded on the DA-98’s tape (see 
10.2.5, “Checking tape TC”
• The timecode used internally by the DA-98 does not 
have to be an actual timecode striped tape. Instead, 
timecode can by “synthesized” from the ABS subcode 
timings, as described in 10.2, “Tape timecode mode”.

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 subframe 
accuracy using the method described above.
10.7.6 Park position
When the DA-98 is slaved to an external timecode 
source, it will take some time between the master 
unit starting to play and starting to transmit time-
code for the DA-98 to read.
These functions allow you to measure and test the 
optimum pre-roll position for the DA-98 (when it 
is a timecode slave) to park itself relative to the 
master timecode device so that it will lock up and 
start playing quickly.
1) Go to menu group 4, move the cursor to 
Park Posi (park position) and press ENTER:
2) The time value shows the current park setting, 
and this can be changed using the 
UP and 
DOWN keys, or the function keys.
10.7.7 Automatic park position setting
When the DA-98 is acting as a timecode slave, it 
can automatically determine the optimum park 
pre-roll position to sync with the master.1) Go to menu group 4, move the cursor to 
Park Posi (park position) and press ENTER:
2) Play and stop the master tape.
3) Turn the DA-98’s 
CHASE on, if it is off.
4) Use the 
UP or DOWN keys to turn the TEST 
parameter on.
The DA-98 will then rewind so that the relative 
difference is zero. When the DA-98 has stopped, 
go on to the next step below.
5) Play the timecode master. 
When the value shown on screen has stopped 
changing and is stabilized, go on to the next step 
below.
6) Turn TEST off (UP or DOWN key). The 
optimum park pre-roll time for the timecode 
master is now stored.
10.7.8 Absolute and relative difference
The offset as set above (10.7.2, “Setting timecode 
offset”) can be called the “absolute difference” 
between the two times. However, if the slave 
machine “wanders” (actually, this is unlikely), the 
offset (theoretical difference) will not be equal to 
the absolute difference. The “relative difference” 
is expressed as below:
Relative difference = Absolute difference – Offset
Thus, if the offset is set on a slave machine to 
+00:10:00:00 (10 minutes) and while chasing, the 
two machines’ counters read as follows:
Park Position
TEST
off 02s08f 25F
Park Position
TEST
off 02s08f 25F
Master 10:15:12:12
Slave 10:05:12:08 
						

							Section 10 – Operations related to timecode
06/97 – 1.00 – 10-13
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 value will be 
shown on the bottom line of the display screen.
10.7.9 Rechasing timecode
When timecode is received, the DA-98 can either 
constantly monitor the internal off-tape timecode 
(or the ABS equivalent as set in 10.2, “Tape time-
code mode”) and the external timecode, issuing 
“speed-up” and “slow-down” messages to the 
transport to keep itself in sync (rechasing), or it 
can synchronize once and run freely, ignoring the 
incoming timecode.
While the DA-98 is re-syncing (speeding up and 
slowing down), playback output will be muted, 
unless the clock is set to 
INT). Usually you should 
find that the DA-98 does not need to rechase, 
however, and you can leave it in free-running 
mode. If the timecode master tape includes a break in the timecode, though, you may want the 
DA-98 to rechase the master.
As well as selecting rechase, you can also select 
the length of the “rechase window”. This means 
that if the difference between internal and incom-
ing timecode is greater than the value of this win-
dow (1 or 2 seconds in the case of the DA-98), the 
synchronizer will start to rechase.
1) Go to menu group 4, move the cursor to 
Rechs Mod (rechase mode) and press 
ENTER:
2) Use the 
LEFT and RIGHT keys to select the 
Mode field, and the UP and DOWN keys to 
choose between 
rechase and free. 
3) If you select 
rechase, use the RIGHT key to 
move to the 
Window field, and select a window 
of either 
1 or 2 seconds.
10.7.10Bypassing timecode errors
As timecode is received from a remote master 
unit, it may be subject to errors (dropouts on the 
timecode master tape, etc.). These errors can 
cause synchronization failure (the DA-98 will no 
longer be locked to the timecode of the master 
unit).
You can set the DA-98 to bypass and ignore 
incoming timecode errors of up to 30 frames in 
length, or up to 10 frames in length.
1) Go to menu group 4, move the cursor to 
ErrBypass (Error Bypass), and press 
ENTER:
2) Use the 
UP and DOWN keys to select between 
10 and 30 Frame.

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 (timecode chase record), and 
press 
ENTER:
2) Use the 
UP and DOWN keys to select between 
enable (individual recording is possible 
while chasing to timecode) and 
disable (all 
chasing units will follow the record status of the 
first unit).

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.
11.0.1 Selecting the control source 
(protocol)
1) Go to menu group 3, move the cursor to 
Ctrl Prt (control protocol) and press 
ENTER:
2) Use the 
UP and DOWN keys to select between 
9Pin, MIDI, Bus and off.
These are all self-explanatory, except for the Bus 
setting, which refers to the sync/control bus carried 
through the 
RS-422 connector [40]. An example 
of a device which can use this protocol is the TAS-
CAM ES-61 editing controller.
11.1 Use with 9-pin external 
control
The RS-422 control allows the DA-98 to be con-
trolled by a number of different editor/controllers, 
in the same way as a VTR or DAT.
11.1.1 Video clocking
If the DA-98 is to be controlled by a video editor, 
it is essential that the DA-98 and the controller 
receive identical video signals from the same 
source (a video generator, for example). The DA-98 should also be set with video resolve 
set to 
on, either free-running or rechase (see 10.6, 
“Video resolution”).
The 
CLOCK switch of the DA-98 [30] should be 
pressed until the 
VIDEO indicator lights.
11.1.2 Emulation
The DA-98 is able to emulate a number of differ-
ent units, so that when a Device-ID request is sent, 
the appropriate reply can be sent back in response.
1) Go to menu group 6, move the cursor to 
Eml
Dev
 (Emulation Device) and press ENTER:
2) Use the UP and DOWN keys to select a device 
from the following list:
•PCM-7050
•BVH-3000
•BVU-950
•BVW-75
•PCM-800
•BVH-2000
•DVR-10
•TASCA M
3) Set your editor to control the device which is 
closest to the emulation you have just selected.
If the editor determines its controlling method 
from the reply to Device ID request, you should 
try using IDs starting from the top of the list.
If the editor recognizes “TASCAM” (and there-
fore bypasses video emulation) use the 
TASCAM 
emulation setting.
11.1.3 Record delay
Most recorders (both VTRs and audio recorders) 
drop into record a short time after they receive the 
command to start recording, and editor/controllers 
are programmed to take this into account. 
However, the DA-98 starts recording immediately 
it receives the command. You can compensate for 
this using the Record Delay settings.

NOTE
The selection of an external control protocol does not 
disable the local controls. When an external controller is 
selected, the last control pressed, whether local or 
remote, operates the DA-98.
