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

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”).
