Section 9 – Synchronization with other DTRS units
9-4 – 1.00 – 06/97
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”)

NOTE
If any

are turned on, you will erase your master tape! You may
want to use the tape’s write-protect tab (see 6.3.1,
“Write-protecting cassettes”).
