							Section 9 – Synchronization with other DTRS units  
9-2 – 1.00 – 06/97
It therefore makes sense to set the machine IDs of 
all DA-88s in the chain first, immediately after 
connections have been made with the power off, 
and then turn on power to all units before setting 
the machine IDs of all DA-98s and DA-38s in the 
chain.
9.2.2 Setting machine ID
1) Select menu group 3, move the cursor to Mcn
ID
, and press ENTER:
2) Use the 
UP and DOWN keys to select a value 
from 
1 to 16.
9.2.3 Master/slave settings (CHASE 
mode)
Each unit with an ID greater than 1 is regarded as 
a slave unit.1) On each slave unit, go to menu group 3, move 
the cursor to 
TimeMode and press ENTER:
If the bottom line does not show ABS (if it shows 
TC), press the UP or DOWN key so that ABS is 
displayed.
2) On each slave unit, press the CHASE switch 
[16].
The CHASE indicator will start flashing.
3) Press any of the transport controls on the 
master unit (machine ID 1). The slave unit(s) 
will synchronize and follow the transport 
commands of the master.
When a slave unit is locked to the master unit, its 
CHASE indicator will light steadily.
4) To turn off chase mode on a slave unit, press 
the 
CHASE switch or the STOP key [34] so that 
the 
CHASE indicator goes off.
9.3 Machine offset
It is sometimes necessary to offset a unit in the 
chain relative to the master unit. This offset can be 
set to frame accuracy to a maximum value of 
±02:00:00:00.
9.3.1 Setting machine offset 
1) Select menu group 3, move the cursor to Mcn
Offset
, and press ENTER:

NOTE
When you set the machine IDs, you can set the ID of 
any machine first, but we recommend doing this in a 
standard sequence, working from the head of the chain 
to the end.

2) Use the LEFT and RIGHT keys to select the field 
to be edited (hours, minutes, seconds or 
frames) and the 
UP and DOWN keys to change 
the value of that field.
You can use the function keys as number keys (see 
5.2.2, “Using the function keys as number keys”) 
to enter the value directly.
You can also change the sign of the offset value 
between 
+ and - by moving the cursor to the sign.
3) Use the ENTER key to confirm the setting.
9.3.2 Cancelling machine offset
To cancel machine offset, simply set the offset 
value to 00:00:00:00.
1) Press and hold down the 
UP key and press the 
DOWN key to reset the value in the Machine
Offset
 menu (see above).
Machine offset will now be cancelled.
9.3.3 Setting machine offset “on the fly”
As well as entering an absolute number, it is also 
possible to enter a number “on the fly” as the 
tapes are playing. 
1) On the slave machine, select menu group 3, 
move the cursor to 
Mcn Offset, and press 
ENTER.
2) Make sure chase mode (see 9.2.3, “Master/slave 
settings (CHASE mode)”) is off on the slave 
unit.
3) Use the 
LEFT and RIGHT keys to move the 
cursor to a second “invisible” field to the right 
of the frames field4) Locate the two tapes (master and slave) so that 
they have the right offset.
You can play the tapes and pause them or carry out 
the next operation while one or both tapes is being 
played back.
5) Press either the UP or DOWN key at the correct 
offset time to capture and store the offset.
The current difference between the master and 
slave tapes will be be displayed on the bottom line 
of the display screen and stored as an offset.
9.3.4 An example of setting offsets
A practical example of setting offsets is given 
here.
The master DA-98 contains the tape with the dia-
log and reference tracks from the video worktape. 
Another DA-98 (the slave) has a tape with some 
tracks containing video backing music.It is neces-
sary to produce an offset between the two so that 
when the master is played, the music tracks will 
start at the correct time relative to the dialog and 
reference tracks.
NOTE
There is an “invisible” field immediately to the right of 
the frames field. If you place the cursor there and incre-
ment or decrement the value, you can change the time as 
a whole (as the frame field passes its maximum value, 
the seconds field will increment).

AUTO OFFSET
NOTES
The value entered in this way can be edited later using 
the technique described above.
You cannot determine the offset from an unformatted 
tape, or if either tape is currently displaying a negative 
ABS value.

1) Locate the slave tape with the backing music to 
the start of the music.
The shuttle mode is useful here (see 8.6, “Shuttle 
operations”).
2) Rewind the master to a little before you want 
the music to enter.
3) Make sure the slave is ready to accept an “on-
the-fly” offset entry as described above.
4) Start playing the master DA-98.
5) When the music entry point is reached, press 
the 
UP or DOWN key to capture the offset point.
6) Stop the master, and set the slave into 
CHASE 
mode (see 9.2.3, “Master/slave settings 
(CHASE mode)”).
7) Rewind the master to a little before the music 
entry and start playing.
The slave machine should now follow the transport 
movements of the master, with the appropriate off-
set, so that the music enters at the right point.
9.4 Digital dubbing
When you copy tapes between DTRS units in the 
digital domain, there is no loss of quality. A 
“worktape” or copy is therefore indistinguishable 
from the original. Additionally, the DA-98 uses 
low-cost media (Hi8 video cassettes).You may want to exploit these features of the 
DTRS system to make archive copies, and “safety 
copies” of important material (see 1.5, “Recom-
mended tapes” for our suggestions on tape use).
1) With the power to all units turned OFF, make 
the synchronization connections as described in 
9.1, “Synchronization connections”.
Remember to terminate the slave unit.
2) Connect the DIGITAL I/O [45] of the master unit 
(source) to the 
DIGITAL I/O of the slave (target).
Use only the approved cables (PW-88D or PW-
88DL) to connect the DTRS units. Use of any 
other cables can cause damage to the units and will 
invalidate the warranties.
3) Turn on both units. Make sure the machines’ 
IDs are correctly set (see 9.2.2, “Setting 
machine ID”).
4) Insert the master tape into the source master 
and a blank tape, formatted with the same 
sampling frequency as the master tape, into the 
target slave.
5) Select 
DIGITAL INPUT on the target slave (see 
8.10.1, “Changing between digital and analog 
inputs”).
6) Put the target slave machine into 
CHASE mode 
(see 9.2.3, “Master/slave settings (CHASE 
mode)”).
7) Locate the master tape to a point before the 
material you want to duplicate.
The target slave will also locate since it is in 
CHASE mode.
8) Arm all tracks (REC FUNCTION) on the target 
slave machine.
9) Make sure that all 
REC FUNCTION switches on 
the source master are turned OFF.
NOTE
When you copy tracks from DA-88 units, the word 
length should be set to 16 bits (see 8.10.2, “Selecting 
word length”)

10) On the master machine, hold down RECORD 
and press 
PLAY.
No recording will take place on the source master, 
but the tracks will be recorded digitally on a one-
to-one basis to the target slave.
There is no need to carry out any special pre-dub-
bing procedure such as timing the digital output – 
the digital and analog outputs are separate.
You can use the Track Copy functions on the target 
slave machine (see 8.11, “Routing digital inputs”) 
to transfer tracks from the source master tape to 
different tracks on the target slave. Note that you 
cannot combine tracks by this method.
9.4.1 Synchronized formatting
When several units are connected together, you 
can format several tapes simultaneously, using one 
machine as the master. This can be a very conve-
nient way of saving time and effort.
1) Make sure that all machines are connected 
together using the 
SYNC connections, as 
described above, and that the last unit in the 
chain is terminated.
2) Load a blank unformatted tape into each 
DTRS unit.
Make sure all tapes are the same length.
3) Press the CHASE switch [16] on all of the slave 
DTRS units. The indicator will flash.
4) Press 
FORMAT/Fs [6] twice within five seconds, 
on each of the DTRS units (master and all 
slaves) so that all 
FORMAT indicators are lit.
The first time you press the FORMAT/Fs switch, 
the indicator will flash. Press it again within five 
seconds to select format mode. If you wait more 
than 5 seconds, the indicator will stop flashing.
If you press the 
CLEAR key [11] while the 
FORMAT indicator is lit steadily, you will cancel 
the format operation.
5) Select the same sampling rate (48kHz or 
44.1kHz) on each DTRS unit.
Any slave DTRS unit which has a different sam-
pling frequency selected from that selected on the 
master will display an error message.
6) Press and hold PLAY and press RECORD on the 
master. All slave units’ 
CHASE indicators will 
light steadily, and the tapes will start to be 
formatted in synchronization.
9.4.2 Recording while formatting
As with a single-machine format (see 6.1.2, 
“Recording while formatting”), it is possible to 
record while formatting.
You may want to use this feature when making a 
live multi-machine recording, and there has not 
been time to format all the tapes in advance of the 
performance.
Remember that you should let the tapes run to the 
end–you should not halt the formatting/recording 
process part of the way through the tape.
9.5 Error messages
These error messages refer to DTRS 
synchronization:
Appears if the digital cable is not connected.. Re-
connect the correct cable to the 
DIGITAL I/O 
connector.
Appears when the sync cable is not connected, the 
master has been turned off, or the master’s sam-
pling frequency is different from that of the slave 
unit’s. Recheck these parameters.
If either of these messages appears, correct the 
fault, and press the 
ESCAPE key to return to nor-
mal operation.

10 – Operations related to 
timecode
The DA-98 contains synchronization facilities, 
including a timecode generator, which allow it to 
act either as a timecode master or a timecode 
slave.
If timecode is recorded, a special discrete subcode 
track is used, which leaves all eight tracks free for 
recording and playback of audio material.
However, the DA-98 is able to synchronize with 
external timecode devices, even if the DA-98 tape 
has not been striped, by converting its internal 
servo subcode (ABS) to timecode “on-the-fly”.
A full range of options is provided for full com-
patibility with the widest possible range of other 
equipment.
10.1 ABS and SMPTE/EBU 
timecode
In some menus, by the time value, you may see 
either 
ABS or TC. Here, we explain these two dif-
ferent timing reference methods and the differ-
ences between them.
10.1.1 ABS time
“ABS” stands for “Absolute”, and is the absolute 
time of the tape as recorded on the subcode of the 
tape. This timing starts at the beginning of the tape 
with a value of 00:00:00:00. This is the timing ref-
erence used when the DA-98 is not using SMPTE/
EBU timecode.
Timecode (whether SMPTE or EBU) contains a 
fixed number of frames per second. However, the 
ABS method of timing works in a slightly differ-
ent way.
In three seconds of time, there are 100 frames. 
These frames are allocated as follows:This pattern is repeated every three seconds, as 
you will notice when you set frame values using 
the menu system in ABS mode. When multiple 
DTRS units are connected together in DTRS sync 
mode, the master unit always outputs ABS tim-
ings to the slave unit(s).
10.1.2 Tape timecode
“TC” stands for timecode, and is shown whenever 
a SMPTE/EBU timecode value is used rather than 
the ABS value. The timecode may be internal or 
external and can be SMPTE/EBU, received and 
transmitted via the 
TIME CODE IN/OUT jacks [37], 
or SMPTE/EBU timecode synthesized from the 
ABS subcode (see 10.2, “Tape timecode mode”).
Whether the SMPTE/EBU timecode is generated 
or synthesized, we will refer to it as “timecode” in 
this manual, to distinguish it from ABS timing 
values.
SMPTE/EBU timecode can be re-produced inde-
pendently of ABS timings and can be of any frame 
format supported by common timecode standards.
When multiple DTRS units are connected, and the 
master unit’s 
CHASE mode is set on, the master 
will chase to any incoming timecode, regardless 
of whether timecode or ABS timings have been 
selected as the time mode (see 10.1.3, “Selecting 
TC or ABS timing” below).
Timing information received and transmitted from 
and to external controllers (e.g. RS-422, MIDI or 
Bus) will always be referenced to timecode 
values.
When the DA-98 is referenced to its absolute 
timecode, the 
ABS indicator to the left of the tape 
counter [2] will light, and when referenced to 
timecode (internal or external), the 
TC indicator 
will light.

NOTE
This procedure is fundamental to synchronization oper-
ations. If you select absolute timing mode when you 
want to synchronize with timecode, you will be unable 
to synchronize the DA-98.  
						

							Section 10 – Operations related to timecode  
10-2 – 1.00 – 06/97
To change between the two different time refer-
ence modes, perform the following procedure:
1) Select menu group 3 and press 
ENTER:
2) Select 
Time Mode and press ENTER.
3) You can use the 
UP and DOWN keys to select 
either 
ABS (absolute) or TC (timecode).
The appropriate indicator by the tape counter 
(either 
ABS or TC) will light.
10.1.4 Location point settings
10.2 Tape timecode mode
The following procedure allows you to select the 
source for tape timecode (including ABS timings 
used to synthesize SMPTE timecode. This synthe-
sized timecode is treated exactly as if a tape had 
been striped with timecode).
1) Go to menu group 5, move the cursor to 
Tape TC, and press ENTER:
2) Use the 
UP and DOWN keys to choose between 
the various options: 
TcTrack, ABS, ABS-
Ofs
, ABS-13 and ABS-23.
These options are all described individually below.
10.2.1 TcTrack setting
This is the one setting in this menu which does not 
use the ABS conversion facility. You should only 
use this setting if you have already striped the ded-
icated timecode track with timecode (either from 
an external source or from the DA-98’s own inter-
nal generator).
If you have selected 
TcTrack in the menu 
above, any timecode recorded on the tape will be 
used as the tape timecode source. 
10.2.2 ABS setting
If you have selected ABS in the menu above, the 
ABS subcode time from the tape will be used as 
the timecode, with the start of the tape having a 
timecode value of 00:00:00:00, as with the ABS 
code itself. 
The timecode frame rate used will be the frame 
rate as selected in 10.3, “Selecting the frame 
rate”).
10.2.3 ABS-Ofs setting
As with the previous setting, this converts the 
ABS subcode timing to timecode, but allows you 
to add an offset to the absolute value so that the 
timecode does not start at the zero point.
When you select this option, the display will 
change to allow you to enter an offset time:
Mcn ID Ctrl Prt
McnOffset Trk Arm
TimeMode
ABS
NOTE
If you change an offset value (timecode or ABS), any 
punch points, location memories, etc. will be invali-
dated. For example, if you change the offset to 
00:30:00:00 (30 minutes) from 00:00:00:00 (no offset), 
a punch point which was previously at 00:33:00:00 (33 
minutes into the tape) will still have the same value 
(00:33:00:00), but will now be only 3 minutes into the 
tape.

NOTE
If you are using ABS timings as timecode, the hours, 
minutes and seconds of the ABS time will correspond to 
the converted timecode, unless
 the frame rate is set to 
29.97 non-drop or 30 drop. In these cases, the difference 
between ABS values and timecode values will be about 
2 seconds per hour.

1) Use the LEFT and RIGHT keys to choose the field 
to change (hours, minutes, seconds or frames) 
and then use the 
UP and DOWN keys to change 
the value of that field.
You can also enter a time offset directly using the 
function keys (see 5.2.2, “Using the function keys 
as number keys”).
The time you enter will then be the time at which 
the timecode starts from the beginning of the tape. 
For instance, if you enter an offset of 00:59:00:00, 
and the tape is positioned exactly 1 minute after 
the start, the timecode will be 01:00:00:00.
10.2.4 ABS-13 and ABS-23 settings
These settings are useful if you are recording 
many pieces on one tape. They automate the pro-
cess of providing a timecode “pre-roll” and start-
ing each piece at an easily-memorable timecode 
position.
The ABS-13 setting should be used to record 
pieces of 10 minutes or less in length, and the 
ABS-23 for pieces of 20 minutes or less.
With both of these settings, the start of the tape is 
automatically set with an offset of hh:57:00:00, 
where hh is the number of hours.
1) Use the 
LEFT and RIGHT keys to select the 
“hours” field.
2) Use the 
UP and DOWN keys to set the “hours” 
value.
Here we assume (for simplicity) that the “hours” 
value has been set to 00. If you set this to a differ-
ent value, add the appropriate offset as you read 
this explanation.
Timecode is synthesized, starting at 00:57:00:00, 
allowing three minutes of timecode “pre-roll” 
before the nominal start of the piece at 
01:00:00:00.
With 
ABS-13 selected, once the tape is posi-
tioned approximately 13 minutes from the start, the timecode will restart at 01:57:00:00. If 
ABS-
23
 has been selected, this will occur approxi-
mately 23 minutes after the start of the tape (the 
piece is 20 minutes long). This allows another 
track to begin at 02:00:00:00.
This process continues until the end of the tape is 
reached. Wherever the tape is located, this calcu-
lation will be performed, allowing you to locate 
each track easily with reference to the timecode 
values.
The diagram below shows the relationship 
between the “synthesized” timecode and the abso-
lute time on tape, assumiong that the “hours” 
value has been set to 00.
10.2.5 Checking tape TC
The TAPE TC indicator by the tape counter will 
light when timecode recorded on tape or synthe-
sized from ABS is being read. The indicator will 
not light in areas of the tape where no timecode 
has been recorded if 
TCTrack has been 
selected, and will not light at the beginning or end 
of tape if any of the ABS modes has been select-
erd. Timecode is not read in STOP mode and the 
indicator will not light in STOP mode. 
As well as the tape counter, the display screen can 
also be used to show tape timecode values and the 
frame rate currently recorded on tape, as described 
below.
1) Go to menu group E, and move the cursor to 
Tape TC:

10-4 – 1.00 – 06/97
2) Start playing the tape.
3) The selected timecode value will be displayed 
on the bottom line, together with the frame rate 
of the timecode. 
The frame rate displayed depends on the timecode 
frame rate as recorded on the tape (if 
TC
Track
 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).
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.
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.
To change the frame rate in other cases, follow the 
procedure below:
1) Go to menu group 5, move the cursor to 
TC
Frame
, and press ENTER:
2) Use the 
UP and DOWN keys to select the frame 
rate for your project.
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 
provided to adjust sampling frequencies to drop-
frame rates, etc.
1) Go to menu group 8, move the cursor to 
Fs
Shift
, and press ENTER:
2) Use the 
UP and DOWN keys to select between 
Pull Down 30NDF, Pull UP 29.97
NDF
, Pull UP 29.97 DF, Pull Down
30DF
 and off.
The PULL UP/DN indicator by the tape counter [2] 
will light if the setting is anything other than 
off.
10.4 Timecode input and 
output
Only timecode (not ABS timing) can be transmit-
ted and received via the 
TIME CODE IN and OUT 
jacks. ABS timings are used for multiple DTRS 
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).
To view incoming timecode, follow the procedure 
below:
TC Frame Mode
29.97 NDF
Fs Shift Mode
off
NOTES
• This setting is not memorized in the backup memory–
you must reset it every time the DA-98 is turned off and 
on again.
• The clock source must be set to 
INT when using the Fs 
shift function to pull up, and to 
VIDEO when using this 
function to pull down.
• If vari speed is enabled (see 8.5, “Vari speed (pitch con-
trol)”, it is not possible to use the Fs shift function.
• When the Fs shift mode is operational, you cannot 
change the timecode frame rate (see 10.3, “Selecting the 
frame rate”). 
						

							Section 10 – Operations related to timecode
06/97 – 1.00 – 10-5
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.
The EXT TC indicator will light when timecode is 
received.
10.4.2 Timecode output
The timecode received at the TIME CODE IN jack, 
or the timecode recorded on tape, can be output 
from the 
TIME CODE OUT jack.
When the DA-98 is the timecode master, the time-
code it outputs should be off tape.
However, when the DA-98 is in the middle of a 
timecode chain, you will probably want to retrans-
mit the incoming timecode (the 
OUT functions as 
a 
THRU).
1) Go to menu group 5, move the cursor to 
OutTc Src (output timecode source), and 
press 
ENTER:
2) Using the UP and DOWN keys, select one of the 
three options: 
Tape; timecode will be replayed 
off-tape, 
External (regen); the external 
timecode will be re-generated by the DA-98’s 
generator, resulting in a clean signal, or 
External (reshape); the timecode signal will be simply filtered before being re-
transmitted.
10.4.3 Timecode output format
This Fast LTC function controls the way in 
which timecode is output when fast winding the 
tape, or if shuttling is carried out at greater than 
normal playback speed.
The 
5 Frame setting means that timecode infor-
mation is not output continuously. Here, the DA-
98 reads the timecode from the tape as it is spool-
ing, outputs 5 consecutive frames at normal speed 
starting with the value which has been read from 
tape, then reads the tape again, outputs another 5 
consecutive frames based on the new tape posi-
tion, and so on.
The 
Leap setting means that timecode is output 
continuously during fast operations, and will not 
be contiguous (it will leap between frames).
The 
off setting means that timecode is not out-
put during fast operations.
1) Go to menu group 5, move the cursor to 
Fast LTC and press ENTER:
2) Use the 
UP or DOWN keys to select the option as 
described above.
10.4.4 Timecode output timing
Because of the nature of the digital-to-analog con-
version, the timecode which is output from the 
DA-98 must be synchronized to match the audio 
timing from either the digital or the analog audio

External (regen)NOTE
When the DA-98 is in CHASE mode, and the timecode 
output has been set to 
TC Track (see 10.2.1, 
“TcTrack setting”
), the timecode output from the 
DA-98 will be the received timecode, with the offset 
value added or subtracted from it. This means that any 
other DTRS units slaved to the timecode output do not 
need to have separate offset settings, but can use the 
master DA-98’s offset.
