3.9 Example of systems for VTR (1 unit) and DA-98 (1 unit)
This is a post-production system consisting of the DA-98, one WR-DA7 and a video recorder. The
SMPTE timecode output is generated from the video recorder and is supplying timecode to the
DA-98. Receiving the SMPTE timecode, the DA-98 supplies the timecode and the wordclock to the
WR-DA7. In this mode, editing operation becomes possible by the use of the AUTOMATION feature
in synchronization with the timecode of the video recorder. In this system, House Video Sync is
used as the wordclock master.
Method of connection
With the DA7 powered off, insert the option card WR-TDIF in Slot 1 of the WR-DA7 and firmly fas-
ten it to the mixer with the supplied screws. Make the setting for the DA-88 with the dip switches
on the WR-TDIF card (SW1, 2 to OFF, respectively).
Connect the WR-TDIF card from the WR-DA7 to the DIGITAL I/O (TDIF-1) of the DA-98 and press
the DIGITAL IN switch of the DA-98 front panel to select the digital input mode.
Connect House Video Sync to VIDEO IN (BNC) of the video recorder and the DA-98.
Connect the WR-DA7 to the MIDI IN/OUT of the DA-98 using a MIDI cable to use the MMC and
MTC functions.
For timecode, MTC is received from the MIDI connection. (Using the option card WR-SMPT, it is
also possible to receive the SMPTE timecode. In this case, the TIME CODE OUT (XLR) of the DA-
98 is connected to the SMPTE IN (XLR) of the WR-DA7.)
When using the DA-88 in place of the DA-98, connect WORD SYNC OUT of the DA-88 to WORD
CLOCK IN of the WR-DA7 using a BNC cable and set the WR-DA7 wordclock termination to 75
Ohm=ON.
WR-DA7 setting
The DA-88 functions as the wordclock master and the WR-DA7 as a slave unit. Set the SOURCE
SELECT to ‘WCK IN’ in the INPUT SET screen of the D-I/O of the WR-DA7. (For DA-98, 38 connec-
tions, synchronization with the SLOT and V-SYNC is also possible.)
To set the MIDI channel for MMC, set MMC PORT to ‘MIDI’ in the MIDI SETUP screen and select
the MIDI channel setting.
To receive MTC timecode, set MTC PORT to ‘MIDI’ in the MIDI SETUP screen.
To display MTC on the DA7’s LCD screen, set TIME BASE to ‘MTC’ in the EXECUTE screen of
AUTOMATION.
(To use the SMPTE timecode set TIME BASE to ‘SMPTE.’)
DA-98 setting
Operation of the DA-98 is synchronized with the SMPTE timecode being generated from the video
recorder.
To enable DA-98 operation synchronized with the SMPTE timecode, press the CHASE switch on
the front panel and set CHASE to ‘ON.’
Set the machine ID number of the DA-98 to 1. (ID=0 for the DA-88)
