3.8 Example of systems for VTR (1 unit), ADAT (1 unit), and BRC 
This is a post-production system consisting of the ADAT and the BRC, in addition to the WR-DA7
and a video recorder. The SMPTE timecode output is generated from the video recorder, this out-
put goes to the BRC. The BRC supplies the timecode and the wordclock to the ADAT and the WR-
DA7. Editing and Automation becomes possible in synchronization with the timecode from the
video recorder. 
Method of connection 
Insert the option card WR-ADAT in Slot 1 of the WR-DA7 and firmly fasten it to the Da7 with the
supplied screws. 
Connect the WR-ADAT card from the WR-DA7 to the DIGITAL IN/OUT of the ADAT using an optical
cable and press the DIGITAL IN switch on the ADATÕs front panel to select the digital input mode. 
Route the SMPTE timecode from the video recorder to the SMPTE IN (Phone Jack) of the BRC so
that the BRC is synchronized with the timecode of the video recorder. 
To use the BRC as the clockmaster, connect WORD OUT (48kHz) of the BRC to WORD CLOCK IN
of the WR-DA7 using a BNC-BNC cable and set the WR-DA7 termination at 75 Ohm=ON. 
Use MIDI cables to connect the WR-DA7 to MIDI IN/OUT of the BRC. This makes MMC and MTC
functions possible. 
For the timecode, MTC is received from the MIDI connections. It is possible to receive SMPTE
timecode using the WR-SMPT option card (XLR: 1,3-GND, 2-SIGNAL) in the WR-DA7.) 
WR-DA7 setting 
To use the WR-DA7 as a slave unit, set SOURCE SELECT to ÔWCK INÕ in the INPUT SET screen of
the D-I/O. (For synchronization with the ADAT card source, set SOURCE SELECT to ÔSLOT1.Õ) 
For MMC, set MMC PORT to ÔMIDIÕ in the MIDI SETUP screen. The MIDI channel of MMC should
be set to the same MMC channel being received on the BRC. 
To receive MTC on the DA7, set MTC PORT to ÔMIDIÕ in the MIDI SETUP screen. 
To view MTC on the DA7Õs LCD screen, set TIME BASE to ÔMTCÕ in the EXECUTE screen of
AUTOMATION. (To use the SMPTE timecode, set TIME BASE to ÔSMPTE.Õ) 
ADAT setting 
For ADAT wordclock setting, connect a Sync cable from the BRC and turn on the power supply. At
this time, setting is automatically made to ÔEXTÕ and the ADAT works as a slave machine for the
BRC. 
Regarding the power supply for the ADAT and the BRC; the power supply for the ADAT should be
turned on first, then, the power supply for the ADAT should be turned on next. 
The audio input of the ADAT is used in the digital input mode. Therefore, the DIGITAL IN switch
should be selected. 
During ADAT playback, there is no output if ALL INPUT is ON. ALL INPUT must be turned OFF.  
						

							35
BRC setting 
To synchronize the BRC with the SMPTE timecode from the video recorder set Locate Reference to
ÔSMPTE InputÕ and Clock Source to ÔInternalÕ by selecting the EXT SYNC setting for the BRC. Then,
turn on the EXT SYNC switch. 
Select the Fixed Mode when the BRC is used as a clockmaster and if the sampling rate is set at
48kHz. Select the Variable Mode when the sampling rate is set at 44.1kHz. Press the PITCH DOWN
switch to setting -147cent ( Ô44.1Õ display). 
For MTC setting, select MIDI in the GEN SYNC setting area to ÔMTCÕ and turn on the GEN SYNC
switch. 
For SMPTE select SMPTE in the GEN SYNC setting area to Ô-10dBÕ and turn on the GEN SYNC
switch. 
To obtain a timecode output from the BRC even during FF/REW operation of the ADAT, set the dis-
play to 8: Output Rew/FF SMPTE & MTC to ÔONÕ in MIDI/UTIL setting of the BRC. 
To accomplish MMC operation, there must be coincidence of the MIDI channel between MMC
output from the WR-DA7 and MMC received on the BRC. On the BRC, set the display to 11: MIDI
Device screen by MIDI/UTIL setting. Set the value of ÔMIDI channel set for the WR-DA7 - 1.Õ
Otherwise, setting should be made to ÔALL.Õ 
A ÔCHANNEL STATUS CRCC ERRORÕ may be displayed during
Digital recording from the DA7. 
This is; however, a message in regards to the sub-code signal,
even with this being displayed proper audio recording and play-
back should be performed.

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 powed off, insert the option card WR-TDIF in Slot 1 of the WR-DA7 and firmly fasten
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 ÔWCK INÕ 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 ÔMIDIÕ in the MIDI SETUP screen and select
the MIDI channel setting. 
To recieve MTC timecode, set MTC PORT to ÔMIDIÕ in the MIDI SETUP screen. 
To display MTC on the DA7Õs LCD screen, set TIME BASE to ÔMTCÕ in the EXECUTE screen of
AUTOMATION. 
(To use the SMPTE timecode set TIME BASE to ÔSMPTE.Õ) 
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 ÔON.Õ 
Set the machine ID number of the DA-98 to 1. (ID=0 for the DA-88)  
						

							38
To enable the DA-98 to receive digital input from the TDIF-1, press the DIGITAL IN button on the
front panel. 
When the timecode output of the video recorder is generated after being converted to MTC, the
MODE dip switch 6 on the SY-88 rear side is set to OFF. (If this switch is set to ON, the timecode
recorded on the tape is converted into MTC and the resultant output is generated.) 
Use the tape where the recorded timecode has the same frame rate as that of the SMPTE timecode
output generated from the video. It is impossible to perform operation synchronized with the
SMPTE timecode of the video recorder if no timecode is recorded in the tape or there is failure in
coincidence of the frame rate. 
Turn on the CHASE switch of the DA-98. 
Set the dipswitch 8 at ON the SY-88 board. 
While ALL INPUT is ON; no playback is generated. To realize playback, ALL INPUT should be set to
OFF. 
A ÔCHANNEL STATUS CRCC ERRORÕ may be displayed during
Digital recording from the DA7. 
This is; however, a message in regards to the sub-code signal, even
with this being displayed proper audio recording and playback
should be performed.
