2.5 DAT (with AES/EBU or S/PDIF I/O)
To record and playback using the DAT Recorder as the wordclock master and the WR-DA7 as a
slave, connect the DAT to the REC OUT and 2TR IN terminals of the WR-DA7. Press the D-I/O
switch on the WR-DA7 to display the INPUT SET screen on the D-I/O so that synchronization is
secured with the digital audio signal of the DAT. Then, set the SOURCE SELECT to  Ô2TR IN A.Õ 
To record and playback using the WR-DA7 as the wordclock master and the DAT as the slave, con-
nect the DAT to the REC OUT and 2TR IN terminals of the WR-DA7, and select a wordclock source
to another device other than the DAT connected to 2TR IN A. 
To record with the S/PDIF output of the WR-DA7 connected to the DAT, please note that some DAT
units may not operate in the normal recording mode. In this case, the connection between the
WR-DA7 and the DAT should be made using the AES/EBU digital audio terminals. 
2.6 Digital timepiece 
Note the following: when setting up a system using the Mark of the Unicorn Digital Timepiece
(DTP). 
When an ADAT is connected to the DTP using an ADAT Sync cable and the DTP is the master
machine the ADAT is synchronized using the timecode being generated by the DTP. Therefore, the
timecode of the DTP is kept unchanged even though the operation of PLAY and REC is performed
on the ADAT. For this reason, the ADAT cannot be synchronized with the timecode and normal
operation cannot be performed. 
When the DA-98, 88, or 38 is controlled by the DTP, the DTP functions as the master unit and the
others operate as the slave. Therefore, set the machine ID to another ID other than ID=1 for the
DA-98 or 38, set at something other than ID=0 for the DA-88. When the CHASE switch of the DA-
98, 88, or 38 is set to ON, each unit works as a slave unit to the DTP and all other units run in syn-
chronization with the DTP. 
When the DTP is used as the MIDI interface with MMC from the WR-DA7 for the ADAT or the DA-
98, 88, or 38 connected through the DTP and the SYNC cable, the following operation takes place: 
FF/REW operation: Stops where the timecode makes leading of less than
10 seconds. 
REC operation: REC is effected upon the cancellation of the record
standby condition. No recording is performed. 
When using the VIDEO OUT of the DTP as the wordclock source for the WR-DA7, the WR-DA7 may
be in a mode where the VIDEO frame rate of the DTP cannot be recognized correctly. Recognition
is not possible when the DTP frame rate is set to any rate other than 59.94 (frames/second).
