3.4 Example of systems with 3 DA-88s
This is a 24-track digital recording system that uses three DA-88Õs. The DA-88 can generate SMPTE
timecode and MTC by using the optional SY-88 SYNC card installed into the DA-88. By using the
MIDI connections between the WR-DA7 and the DA-88, it is possible to perform MMC (MIDI
Machine Control) from the WR-DA7. 
Method of connection 
With the DA7 powered OFF insert the WR-TDIF (option card) in Slot 1, 2, 3 of the WR-DA7 and
firmly fasten them to the console with the supplied screws. Using the dip switches on the WR-TDIF
card make the proper setting for the DA-88 (SW1, 2 to OFF, OFF respectively). 
Connect the WR-TDIF card of the WR-DA7 to the DIGITAL I/O (TDIF-1) of the DA-88 using cable
(PW-88 DL) and press the DIGITAL IN switch of each DA-88 to select the digital input mode. 
Connect each DA-88 with the PW-88S SYNC cables in the sequential order from SYNC OUT to
SYNC IN. Connect the terminator to the SYNC OUT terminal of the DA-88. 
To use the DA-88 as the wordclock master, connect the WORD SYNC OUT of the DA-88 to WORD
CLOCK IN of the WR-DA7 using a BNC-BNC cable (Part # DA-BNC: Available in the USA) and select
the WR-DA7 termination at 75 ohm to ON. 
For MIDI connections, connect the WR-DA7 to MIDI IN/OUT of the SY-88 using a MIDI cable. It is
possible to use the MMC and MTC functions. 
For the timecode, MTC is received from the MIDI connection. (Using the option card WR-SMPT, it
is possible to receive the SMPTE timecode. In this example, the TIME CODE OUT (RCA Pin Jack)
of the DA-88 is connected to the SMPTE IN (XLR: 1,3-GND, 2-SIGNAL) of the WR-DA7.) 
WR-DA7 setting
The DA-88 functions as the wordclock master and the WR-DA7 as a slave unit. In the INPUT SET
window of the D-I/O area on the top panel of the WR-DA7 set the SOURCE SELECT to  ÔWCK INÕ 
(In the case of DA-98, 38 connections, synchronization with the SLOT and V-SYNC is also possi-
ble.)  
In regards to the MIDI channel of MMC set the MMC PORT to ÔMIDIÕ in the MIDI SETUP screen
and make the proper MIDI channel settings. 
To receive MTC Timecode, set the MTC PORT to ÔMIDIÕ in the MIDI SETUP screen. 
To display the MTC timecode on the LCD display, set the TIME BASE to ÔMTCÕ in the EXECUTE
screen of AUTOMATION window. 
(To use the SMPTE timecode by connecting the optional WR-SMPTE card, and set the TIME BASE
to  ÔSMPTE.Õ)  
						

							25
DA-88 setting 
Since the DA-88 receives digital input data from the TDIF-1, press the DIGITAL IN switch on the
control panel. 
The machine ID number of the DA-88 is 0 for the wordclock master unit. These machine ID num-
bers are set at 0, 1, 2, and 3 using the rear rotary switch in the sequential order of the SYNC cable
connections attached from SYNC OUT to SYNC IN. 
(* For the DA-98 and 38, machine ID numbers are set at 1, 2, 3, 4 in the sequential order of the
connections.) 
Press the CHASE switch on the DA-88Õs front panel with the machine IDs 2 and 3 to select CHASE
to ÔONÕ so that synchronization can be performed with the master DA-88. 
Set the sampling rate of the wordclock master unit to INT 48k or INT 44.1k. The sampling rate of
the DA-88 is automatically changed to the sampling rate of the tape being used. 
No playback is produced when ALL INPUT is ON; For playback, ALL INPUT should be set to OFF. 
For MMC control of the DA-88 from the WR-DA7, set the MODE dip switch #2 to 0 (OFF) on the
rear panel of the SY-88 in order to make the MIDI port effective. 
To produce a timecode output from the DA-88 in synchronization with the digital audio data set
the MODE dip switch #5 to 0 (OFF) on the rear panel of the SY-88. 
To output tape-recorded timecode from the DA-88, set the MODE dip switch 6 to 1 (ON) on the
rear panel of the SY-88 Sync board.

WR-DA7 setting 
To use the WR-DA7 as a slave unit, set the SOURCE SELECT to ÔWCK INÕ in the INPUT SET window
of the D-I/O Setup Section on the MASTER unit. 
(For wordclock synchronization using the DA98Õs connection slot, set the SOURCE SELECT to
ÔSLOT1Õ on the MASTER WR-DA7. Keep ÔWCK INÕ on the SLAVE unit.) 
To establish communication between the tandem WR-DA7 units, set the PORT SELECT to ÔTO PCÕ
in the SERIAL I/O SETUP in the MIDI SETUP screen for both the MASTER and SLAVE units. Then
set the baud rates to the same value. 
To send and receive MIDI messages, set the PORT select of Gen.Rx and Gen.Tx to ÔMIDIÕ in the
MIDI SETUP screen. On the TANDEM SLAVE unit, set the SEND/RECEIVE of the various MIDI mes-
sages to ÔTHRU.Õ 
For MMC set the MMC PORT to ÔMIDIÕ in the MIDI SETUP window for the same MMC channels to
be received on the BRC. 
For MTC reception on the WR-DA7, set MTC PORT to ÔMIDIÕ in the MIDI SETUP window of the
TANDEM (MASTER) unit. 
To display the MTC timecode, set the TIME BASE to ÔMTCÕ in the EXECUTE window of AUTOMA-
TION SETUP Window. 
(To use the SMPTE timecode connect the WR-SMPTE option card, and set the TIME BASE to
ÔSMPTE.Õ in the EXECUTE window of AUTOMATION SETUP Window.) 
DA-98, 38 setting 
Since the DA-98 and 38 receive digital input data from the TDIF-1, press the DIGITAL IN switch on
the control panel. 
To set the machine ID numbers of the DA-98 and 38, ID: 1 is assigned to the DA-98. The machine
ID numbers are set to 1, 2, 3, and 4 in the order of cable connections from SYNC OUT to SYNC
IN. 
Select the sampling rate of the DA-98 to INT 48k or INT 44.1k. The sampling rate of the DA-98 is
automatically set off the tape thatÅfs being used. 
Operation of the DA-38 is synchronized with the DA-98, as a slave unit for the DA-98. Therefore,
when the ID is set for any value other than 1, the DA-38 is set to the wordclock from the PW-88S
SYNC cable. 
Press the CHASE switch of the DA-38 front panel with the machine IDs 2, 3, and 4 to select CHASE
to ÔONÕ so that synchronization can be performed with the master DA-98. 
While ALL INPUT is ON; no audio is played back. For playback ALL INPUT should be set at OFF.

Connect the IN/OUT terminal using the recommended cable(Part # DA/DB-XLR M-F: Available in
the USA) of the WR-ADDA card of the WR-DA7 to the IN/OUT terminal of the analog 16-track
recorder. 
The timecode is supplied from channel 16 of the analog recorder to the (optional) SMPTE IN
(XLR: 1,3-GND, 2-SIGNAL) of the WR-DA7. 
WR-DA7 setting 
Set the WR-DA7 to the wordclock master. 
In the INPUT SET screen of D-I/O of the WR-DA7, set SOURCE SELECT to ÔINT 48kÕ or ÔINT 44.1k.Õ

3.7 Example of systems for Digital Video Recorder (1 unit) 
This is a post-production system consisting of the WR-DA7 and the Digital Video Recorder. The
audio signals are connected using the AES/EBU digital audio option card. The WR-DA7 receives
SMPTE timecode from the Digital Video Recorder for itÕs editing and automation operations. 
Method of connection 
Insert the option card of WR-AESS (Slot 1) and the WR-SMPTE (option card) in the WR-DA7 and
fasten them to the console using the supplied screws. Select the switches on the WR-AESS card to
AES/EBU. 
Make the connections to the digital I/O terminals of the WR-DA7 and the Digital Video Recorder
(WR-AESS card: D-sub 25-pin connector, Digital Video Recorder: XLR connector; 
Use the House Video Sync signal to REF IN (BNC) of the Digital Video Recorder, and make the
connection from REF OUT to V-SYNC IN of the WR-DA7. 
The termination of the Digital Video Recorder REF should be set to 75 Ohm=OFF. 
The timecode is transferred from the SMPTE OUT (XLR) of the Digital Video Recorder to the
SMPTE IN (XLR) of the WR-DA7. 
WR-DA7 setting 
Set the SOURCE SELECT to ÔV-SYNCÕ in the INPUT SET screen of D-I/O area in order to produce
synchronization with the V-SYNC input. 
To display the SMPTE timecode received at the SMPTE IN, set the TIME BASE to ÔSMPTEÕ in the
EXECUTE window of Automation Setup Section
Digital Video Recorder settings: To receive AES/EBU digital audio, make the settings of ÔDIGITAL
INÕ on the LCD screen. 
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.
