1) From menu group F, move the cursor to Key 
Mode
, and press SELECT
:
2) Use the UP
 or DOWN
 key to select between 
All and Individual.
If you select 
Individual, only that unit cur-
rently selected for control (see 5.1.1, “Selecting 
the unit to which operations refer”) will be con-
trolled by the three keys mentioned above. If you 
select 
All, then all DTRS units connected will 
respond to the commands of the ALL SAFE
, ALL 
INPUT
 and AUTO  M O N
 keys.
7.2.3 Chasing with an offset
It is not always required that the DTRS units are in 
perfect synchronization with each other.
For instance, it may be that three DTRS units are 
being used for video post-production purposes. 
The dialog and Foley tracks of a project have been 
recorded on one DTRS tape (up to eight tracks), 
and the backing music has been recorded on two 
more tapes (16 tracks). Obviously, the units 
replaying the two music tapes should be synchro-
nized to each other, but the music may need to be 
“slipped” relative to the dialog and Foley unit 
(which is, in turn, synchronized to the timecode 
on the video, as described in 8.1.8, “Chasing to 
external timecode”).
Once the dialog and Foley is synchronized to the 
video timecode, “slipping” the two music units is 
accomplished in the following way:
1) From menu group 3, move the cursor to 
Mcn 
Offset
 and press SELECT
:
2) Choose the first machine which will take the 
chase offset (in the illustration above, we show 
machine 2) by using the SHIFT
 and UP
 (NEXT
) 
keys.3) Use the numeric keypad to enter an offset value 
which is shown on the LOCATE TIME/VALUE
 
display. The +/-
 key of the numeric keypad is 
used to change between positive and negative 
values.
The offset value may be ±
2 hours relative to the 
master time.
You can also use the cursor keys to enter a value 
directly on the display screen.
The Auto Offset function described below can also 
be used to set the offset.
4) Transfer the value to the display screen by 
pressing and holding down the SHIFT
 key [23] 
and pressing the ENTER/LOAD
 key [20].
5) Use the SHIFT
 and UP
 (NEXT
) keys to select 
any other units which will chase with an offset.
When the master DTRS unit plays, the slave units 
should now chase at the offset value you have set 
up. 
If an offset value is set on any unit or units, and 
the Time Mode is set to ABS, the OFFSET
 indi-
cator [10] will light.
If you need to “fine-tune” these values, you can 
use the UP
 and DOWN
 keys to adjust the value of 
the offset while monitoring the playback of the 
units.
If adjustment finer than a frame is required, it is 
suggested that you use the Track Delay function 
(see 7.1.1, “Track delay”).
7.2.4 Auto Offset function
In addition to the manual offset entry, it is also 
possible to set an offset automatically by follow-
ing the procedure below:
1) From menu group 3, move the cursor to 
McnOffset and press SELECT
.

NOTE
There is an “invisible” field immediately to the right of the 
frames field. If you place the cursor there and increment 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). 
						

							Section 7.2 - Unit-related functions  
7-4 
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.
7.2.5 Checking the offset
The offset of a slave DTRS unit relative to its mas-
ter may be checked (“absolute” difference), as 
well as the difference (if any) between the 
intended offset and the actual offset (“relative” 
difference). In practice, usually there will be no 
difference between the intended and actual offset, 
resulting in a relative difference of zero.
As an example, consider the following:
A slave machine has its offset set to +00:10:00:00, 
and while chasing, the two machines’ tape 
counters read as follows:
Here, the difference between the master and the 
slave times (the “absolute difference” is now 
00:10:00:04, and this is what is shown if we exam-
ine the absolute difference.
However, the result of subtracting the intended 
offset from the absolute difference is 4 frames, 
and this is the “relative difference”, which may 
also be examined as described below:1) From menu group E, move the cursor to either 
Abs Diff (absolute) or Rel Diff 
(relative).
There is no need to press SELECT
 here.
2) The appropriate difference value will be 
displayed on the bottom line of the display 
screen.
7.2.6 Clock selection
The word clock (as opposed to the timecode clock 
source) of a DTRS unit is usually selected using 
the 
CLOCK key on the front panel. However, the 
RC-898 can be used to select the input clock. 
• In ABS time mode, the clocks of all DTRS 
units will be set together, following the setting 
of the first machine in the chain. 
• However, as explained below in 8.1.11, “Inde-
pendent clock settings”. they can also be set 
independently.
1) From menu group 9, move the cursor to 
Clock, and press SELECT
:
2) Use the UP
 and DOWN
 keys to select between 
Int and Word and (in the case of SY-88-
equipped DA-88s and DA-98 units) 
Video.
7.2.7 Output timing
On the DA-88, regardless of whether an SY-88 
synchronizer board is fitted or not, there is a facil-
ity to use either Digital or Analog output mode for 
exact synchronization when dubbing between 
DTRS units, etc.
Note that while it is possible to output both digital 
and analog signals simultaneously, there two sets 
of signals will be out of sync with each other.
1) From menu group 9, move the cursor to 
OutputTim (output timing) and press 
SELECT
:

2) Use the LEFT
 and RIGHT
 keys to select a unit, 
and the UP
 and DOWN
 keys to change the 
setting between 
Digital and Analog.
See p15 and pp25-26 of the DA-88 manual for fur-
ther information regarding this facility.
7.2.8 Varispeed (pitch control)
The DTRS design allows for ±6.0% speed control, 
in 0.1% increments.
1) From menu group 0, move the cursor to 
Vari 
Spd
, and press SELECT
:
2) Use the UP
 key to change 
Fix to Vari, or 
the DOWN
 key to change 
Vari to Fix.
The VA R I
 indicator [10] will light if Vari is 
selected, even if the setting is 
0.0%, and will go 
out if 
Fix is selected, even if the setting is not 
zero.
3) Move the cursor to the right (numeric) field, 
and use the UP
 and DOWN
 keys to set the 
value.
7.2.9 Input selection
DTRS units can accept either digital or analog 
inputs. The choice of which inputs are to be used 
for each machine is made in the following way:
1) From menu group 9, move the cursor to 
InputSel and press SELECT
:
2) Use the UP and DOWN keys to select between 
the digital and analog input sources for each 
unit.
In the screen above, units 1 through 4 are accept-
ing analog signals, while 5 and 6 are using TDIF -
1 digital inputs.
7.2.10 Word length
The DA-38 and DA-98 units are able to 
accept digital data at their digital I/O connectors at 
either 16-bit, 20-bit or 24-bit word lengths. These 
settings are made in the following way:
1) From menu group 2, move the cursor to 
Word 
Len
, and press SELECT
:
2) Use the UP
 and DOWN
 keys to select between 
16, 20 and 24 bit word length of incoming 
data, which will be converted to 16 bits for 
recording purposes.
If you select a value higher than 16, you may 
want to experiment with the Dither settings (see 
7.2.11, “Dither”, below), as this may help with dis-
tortion, though a little may be lost from the signal-
to-noise ratio.
7.2.11 Dither
Dithering, in digital audio, is the tech-
nique of adding a known noise signal to a low-
level input signal, especially when converting 
from a word length with a higher number of bits 
than the destination (see 7.2.10, “Word length” 
above).
Paradoxically, this technique removes quantiza-
tion noise and improves overall distortion figures, 
though at the slight expense of the signal-to-noise 
ratio. The DA-38 implements an “on/off” dither 
function, and the DA-98 allows two “shapes” of 
dither. See section 4-8 of the DA-38 manual or 
8.13 of the DA-98 manual for further details.
1) From menu group 1, move the cursor to 
Dither and press SELECT
:
2) Allowable values for DA-38 units are 
on and 
off. The DA-98 allows the following settings 
to be made: 
off, triangular and 
rectangular.
See the section 8.13 of the DA-98 manual for a 
discussion of rectangular vs. triangular dither 
modes.

7.2.12 Confidence mode
 The DA-98 allows off-tape monitoring while 
recording (confidence mode). This can be 
switched on or off on a per-machie basis.
However, since there is a slight delay between the 
input signal and its replay in confidence mode, 
you should not use confidence mode in the follow-
ing circumstances:
• When making punch recordings, as you will 
not be able to hear the exact timings for punch 
operations.
• When operating a mixed chain of DA-98s and 
other units. The delay introduced by confi-
dence mode on the DA-98 will make these 
tracks appear to be out of time with the other 
tracks.
However, confidence mode can be very useful 
when making test recordings so that you can 
instantly hear the effects of different dither set-
tings (see 7.2.11, “Dither”), or to monitor possible 
clipping at high recording levels on a test take, 
allowing you to “back off” the level a little before 
making a final recording.
1) From menu group 9, move the cursor to 
ConfdMod and press SELECT
:
2) Use the UP
 and DOWN
 keys to select between 
the three states: 
off, ready and on.
Confidence mode is selected using this three-state 
switch to prevent accidental switching of the unit 
into confidence mode, which might otherwise 
cause confusion when performing monitoring 
operations.
7.2.13 Reference levels
The reference level for analog I/O on the DA-
98 can be set to one of three standard values: 
European, TASCAM and SMPTE. These levels 
correspond to:1) From menu group 2, move the cursor to 
Ref 
Level
 and press SELECT
:
2) Use the UP and DOWN keys to select between 
-16, -18 and -20 dB.
The appropriate reference level indicator(s) next to 
the meters on the DA-98 unit will light. See sec-
tion 8-7 of the DA-98 manual for further details of 
reference levels.
7.2.14 Meter modes
On the DA-98, the peak hold time and the 
decay ballistics of the meters can be changed.
1) From menu group 2, move the cursor to 
MeterMode and press SELECT
:
2) Move the cursor to the 
Peak Hold setting, 
and choose between the following values: 
0 
through 
9 seconds (in 1-second increments) 
and 
continue.
The continue setting sets an infinite peak 
hold time. The peak levels can be reset by setting 
the time to 
0 seconds.
3) Move the cursor to the Release setting, and 
choose between the following release times: 
Fast, Medium and Slow.
The meter functions are described in section 8.8 of 
the DA-98 manual.
7.2.15 Sine oscillator
The DA-98 incorporates a sine oscillator for 
line-up purposes at either 440Hz or 1kHz. The 
level of the oscillator is a full bit +16dBu (but can-
not be compared to transient signals, on account 
of the constant nature of a sine-wave oscillator).

8 – Timecode functions
This section describes the timecode-based 
functions available through the RC-898. Note that 
while the RC-898 contains no timecode generator 
or reader of its own, it is able to control the time-
code generators and synchronization facilities of 
DA-98 and DA-88/SY-88 units. Since the DA-38 
does not have any timecode facilities, this section 
does not have any relevance if you are using a 
setup composed of only DA-38 units.
Note that in this section, we use the term “time-
code” to refer to SMPTE/EBU timecode rather 
than to ABS timecode.
When using a chain of DTRS units which are to 
be synchronized to external timecode, you will 
usually need to synchronize the first unit in the 
chain. The other units should then chase to the 
first, using the DTRSABS synchronization facil-
ity. For information related to this and to other 
non-timecode-related synchronization features, 
see 9, “External control and settings”.
8.1 Primary timecode 
functions
These functions cover the basic timecode setup 
when synchronizing DTRS units to timecode.
8.1.1 Selecting the timecode source
When using a DA-98 unit, the timecode used 
for recording can be from one of three different 
sources: external, from the internal generator, or 
off-tape (“synthesized” timecode—see 8.1.2, 
“Synthesizing timecode from ABS times”). See 
section 10.5 of the DA-98 manual for further 
details regarding this function.
1) From menu group 8, move the cursor to 
TcRec Src and press SELECT
:
2) Use the UP
 and DOWN
 keys to select between 
External TC, Generator TC and 
Tape.
If you select Tape, there will be another param-
eter shown which will correspond to the timecode 
type selected in 6.4, “ABS setting”. This shows the 
kind of timecode on the tape: striped timecode or synthesized timecode (as described in 8.1.2, “Syn-
thesizing timecode from ABS times” below).
8.1.2 Synthesizing timecode from ABS 
times 
As mentioned earlier, linear timecode 
does not necessarily have to be striped on a tape 
for the DTRS unit to be able to use the TC setting. 
The subcode can be used to synthesize timecode, 
eliminating the need to pre-stripe the tape for 
timecode-based work.
In addition, the DA-98 can add offsets to the 
ABS value, so that the timecode values can start at 
any desired position, or can create a repeating 
timecode pattern for tracks of nominal 10 or 20 
minutes’ duration. See also 10.2.3 and 10.2.4 of 
the DA-98 manual for further details.
1) From menu group 5, move the cursor to 
Tape TC, and press SELECT
:
2) Use the SHIFT
ed UP
 and DOWN
 keys (NEXT
 
and PREVIOUS
) to select the DTRS unit whose 
values you will change.
3) Use the UP
 and DOWN
 keys to choose between 
the following:
•
TC Track: The timecode is read from the 
timecode track striped on the tape. Full details 
of these operations are given in 8.1.7, “Record-
ing the timecode on a DTRS timecode track”..
•
ABS: The timecode is “synthesized” from the 
ABS time (i.e. the ABS values are read and 
used as timecode).
•
ABS-Ofs: You can add or subtract an 
offset from the ABS values to arrive at the final 
synthesized timecode value. If you select 
ABS-Ofs, use the numeric keypad [16] to 
enter an offset value on the LOCATE TIME/
VA L U E
 display [15] and enter it into the offset 
value on the display screen using the SHIFT
 
and ENTER/LOAD
 keys [23]+[20].
•
ABS-13 and ABS-23: provide a con-
venient way of dividing a tape into “sessions”. 
Timecode is synthesized with a pre-roll time of 
xx:57:00:00, the session is assumed to 
start at 
xx:00:00:00, and finishes at 
xx:10:00:00 or xx:20:00:00, depend-

ing on whether ABS-13 or ABS-23 has 
been selected. The value of 
xx varies, depend-
ing on the starting “hour” chosen.
If you select 
ABS-13 or ABS-23, use the 
UP
 and DOWN
 keys to select the starting hour. 
In the illustration above, the starting hour is 0.
8.1.3 Selecting a timecode type
The RC-898 can work with a number of different 
timecode types, as shown by the TC
 indicators 
[7].
The 29 
on the RC-898 panel is an abbreviation for 
“29.97”. The DF
 indicator will light if the time-
code is in drop-frame format.The supported types 
are therefore:
To select or change the timecode type used by a 
DTRS unit:
1) From menu group 5, move the cursor to 
TC Frame and press SELECT
:
2) Use the SHIFT
ed UP
 and DOWN
 keys (NEXT
 
and PREVIOUS
) to select the unit where you 
will make settings.
3) Use the UP
 and DOWN
 keys to change between 
the following settings:•30 DF
•30 NDF 
• 29.97 DF
• 29.97 NDF
•25F
•24F
These types will not, of course, affect the type of 
any timecode which has already been used to 
stripe a tape.
They are used for the type of timecode which will 
be produced by the internal timecode generator of 
a DTRS unit (DA-98 or SY-88) or the synthesis 
from ABS timecode of these units.
8.1.4 Setting the generator start time
The DTRS unit’s internal generator can be set in 
the following way:
1) From menu group 8, move the cursor to 
Gen 
Start
, and press SELECT
:
2) Enter the generator start time using the 
numeric keypad [16].
3) Press and hold down SHIFT
 and press ENTER/
LOAD
 to transfer the value to the display 
screen. 
You can also use the cursor keys and the display 
screen to set the value here.
We suggest that you choose a value such as 
00:57:00:00, allowing a few minutes of lead-
in on the tape before the program material starts.

8.1.3, “Selecting a timecode type”, and is accessed from 
menu group 5. 
If the timecode source is synthesized ABS timecode, the 
timecode type may be changed by changing the timecode 
type of the ABS “timecode”. It is not possible to receive one 
type and convert it for recording, however. If timecode is 
being recorded from an external source, thetype cannot be 
changed.

8.1.5 Starting and stopping the generator
1) From menu group 8, move the cursor to Gen 
Mode
 and press SELECT
:
2) Use the LEFT
 and RIGHT
 cursor keys to move 
between the 
Run/Stop and Mode fields.
3) Use the UP
 and DOWN
 keys in the 
Mode field 
to determine whether the generator will 
Continue from the last point where it was 
stopped, or whether it will be 
Reset to the 
starting value as set above when restarted.
4) When the cursor is on the 
Run/Stop field, 
use the UP
 key to start the generator, and the 
DOWN
 key to stop it again.
8.1.6 Checking the generator progress
While the generator screen above is visible, the 
generator’s output can be viewed in the display 
screen. However, there is also another way to 
check the generator:
1) From menu group E, move the cursor to 
Gen 
TC 
(there is no need to press SELECT
):
The bottom line of the display shows the current 
timecode value being output by the generator. If 
the generator is stopped, it will show the value at 
which it was stopped.
8.1.7 Recording the timecode on a DTRS 
timecode track
This procedure applies to all timecode recording, 
regardless of the timecode source used.
The dedicated timecode tracks of any DTRS units 
can be armed and safed on a per-machine basis:1) From menu group 8, move the cursor to 
TcTrkRec and press SELECT
:
2) Use the UP
 and DOWN
 keys to arm the 
timecode track on the required DTRS unit(s). 
Make sure that all other units’ timecode tracks 
are disabled.
When a unit’s timecode track is armed for record-
ing, and that machine is selected, as shown by the 
MACHINE
 indicators [8], the TC REC
 indicator 
[10] on the RC-898 (as well as the TC REC
 indi-
cator on the DTRS unit) will light.
3) Rewind the tape to the beginning.
It is possible to start recording timecode halfway 
through the tape, but it can make later synchroni-
zation difficult. For this reason, we advise record-
ing timecode all the way through the tape from the 
start (unless you use the ABS-13 or ABS-23 preset 
functions to convert ABS time into synthesized 
timecode, as described in 8.1.2, “Synthesizing 
timecode from ABS times”).
4) Start the timecode source.
If the timecode source is an external source (see 
8.1.1, “Selecting the timecode source”), start the 
source so that timecode is transmitted from it.
If the timecode source is the DTRS internal gener-
ator, start the generator as described in 8.1.5, 
“Starting and stopping the generator”.
If the timecode source is the ABS timing, used to 
synthesize timecode, no separate operation is nec-
essary to start the timecode source.
5) Press and hold down the RECORD
 key and 
press the PLAY
 key.
The TC REC
 indicator on the RC-898 (if the 
DTRS unit is selected) as well as the DTRS units, 
will light steadily.

NOTE
Remember, as mentioned earlier, that it is usually necessary 
to record timecode on only one unit; the other units in the 
chain can use the DTRS chase facility. However, it may be 
necessary, if dubbing audio tracks, etc. between DTRS 
units, to transfer timecode simultaneously with the audio 
tracks. 
						

							Section 8.1 - Primary timecode functions  
8-4
6) To check the off-tape timecode as it is being 
recorded, from menu group E, move the cursor 
to 
Tape TC (there is no need to press 
SELECT
)):
The bottom line of the display shows the current 
timecode value being output from the tape. If the 
tape is stopped, the last timecode read from tape 
will be shown.
External timecode, if it is being used for recording 
or for synchronization purposes, can be read in the 
same way, except that the cursor should be moved 
to 
Ext TC in menu group E.
8.1.8 Chasing to external timecode
When chasing to an external timecode source 
(remember that you cannot chase to MTC), there 
are two cases to be considered. The first is when 
the DTRS unit which will be chasing timecode is 
the first unit in the chain. In this case, there is no 
DTRS sync signal received at the 
SYNC IN con-
nector (of course, the RC-898 provides control 
signals), and hence, pressing the CHASE
 key [32] 
will automatically synchronize the DTRS unit to 
the incoming timecode.
The reference to which the incoming timecode is 
matched, however, depends on the 
Time 
Mode
 settings of the DTRS unit with regard to 
ABS or timecode (see 6.4.2, “Selecting Time 
Mode”).
In the case of a unit which is connected to the 
master DTRS unit in the chain, the situation is a 
little more complex, as the unit must be set up to 
slave to incoming timecode rather than the DTRS 
sync signals. Here, the 
Time Mode menu is 
used once again (6.4.2, “Selecting Time Mode”), 
but here it determines the chase sync source; time-
code or ABS sync.
Note that it is unlikely that you will need to syn-
chronize a slave unit with timecode—typically, 
only the first unit in the chain will be a timecode 
slave, and this will act as a DTRS sync master for 
the other units in the chain.
8.1.9 Chasing with a timecode offset.
If the timecode on the DTRS unit matches the 
timecode coming from the master unit (e.g. the 
DTRS tapes contain a video soundtrack and have 
been striped either concurrently with, or from the 
video tape), there is no need for an offset.
If, however, the DTRS tracks are not linked in this 
way with the master source, an offset is required. 
The offset can be 
±12 hours from the received 
timecode. Timecode “wraps” in a 24-hour clock 
format, so that 12 hours in advance of 13:00:00:00 
is 01:00:00:00, and 12 hours behind 02:00:00:00 
is 14:00:00:00.
1) From menu group 4, move the cursor to 
TC 
Offset
 and press SELECT
:
Note that this setting is made to subframe accu-
racy. The timecode type will be shown in the bot-
tom right of the display screen.
2) Use the numeric keypad to set the offset (use 
the +/-
 key to change values between positive 
and negative).
The value will be shown in the LOCATE TIME/
VA L U E
 display and the OFFSET
 indicator [10] 
will light.
If an offset value is set on any unit or units and the 
Time Mode is set to TC, the OFFSET
 indicator 
[10] will light.
As an alternative to using the numeric keypad, you 
may also use the cursor keys to enter values 
directly into the LCD display.

NOTE
This procedure described here should be used when chasing 
to timecode. When slave machines are chasing to DTRS 
sync from a master DTRS unit, use the procedure described 
in 7.2.3, “Chasing with an offset”.
