2. Notes for connections
with peripheral equipment
2.1 Wordclock
The WR-DA7 as wordclock master
The DA7 has an internal wordclock generator that provides a timing reference for the external
(digital) audio devices connected to it. This is neither MIDI nor SMPTE timecode. You can set the
internal generator to synchronize to either 44.1 or 48K, selectable from The [D-I/O>INPUT SET]
window.
When multiple digital audio devices are used, it becomes necessary to synchronize the audio signals with a single reference timing signal or master wordclock source. In a system where all of the
digital audio devices share a common wordclock it is essential that all of the devices be turned on
even if they are not being used.
The WR-DA7 as wordclock slave
The DA7 can be slaved to an external wordclock source, to accomplish this you must go to the [DI/O>INPUT SET] window. Here you can choose Wordclock In [WCK IN], Video Sync In [V SYNC],
2 track A input [2TR IN A] and Slot 1,2 or 3.
For example: it is possible to select the WR-AESS card as the wordclock source of the WR-DA7.
The DA7 can be synchronized with the digital audio signals being input on Channels 1/2 of the
WR-AESS card. However, when no input is present on Channels 1/2 an UNLOCK status will be displayed. The wordclock synchronization with the other channels will not be realized either.
If the word clock is set incorrectly (for example, a system where multiple equipment units are set
as the wordclock master), noise (usually in the form of clicks and pops) may become audible. It is,
therefore, necessary that all of the slave units be synchronized with the wordclock master unit.
2.2 Installing and using option cards with the WR-DA7:
Be sure to install all of the Option Cards with the power of the DA7 turned OFF. Set the
Dipswitches on the card accordingly for the type of devices being connected.
Insert the card into the WR-DA7. Install all of the supplied mounting screws (for proper grounding) securely to the DA7’s chassis.
WR-TDIF: Set the dipswitches, or switches on the card, according to the devices being
connected.
When connecting a DA-38 or DA-98 (SW1) ON, (SW2) OFF
When connecting a DA-88 (SW1) OFF, (SW2) OFF
7
WR-AESS: Select the switch on the card, according to the digital audio formats
(AES/EBU, S/PDIF) of the unit being connected. It is possible to select settings for each
pair of channels 1/2, 3/4, 5/6, and 7/8.
This switch is used for switching the electrical signal not for format
change.
WR-TNDM: The Tandem card is for use in Slot 3 (only) of both mixers.
WR-SMPT SMPTE Card, carefully follow the steps to install the WR-SMPT according to
the instructions in the owner’s manual.
Wordclock
For proper wordclock connections, it is necessary to terminate the last device in the wordclock
chain. The WR-DA7 allows ON/OFF of the 75-Ohm terminator on the wordclock input.
ON: Is selected when the WR-DA7 is used as a wordclock master or as a slave at the end of
the wordclock connections (terminated at 75 Ohm). (A clock output synchronized with DA7
is generated at the word clock’s output.)
OFF: Is selected when the WR-DA7 is used as a slave, the wordclock input entered in the WRDA7 is transmitted as a through output.
MIDI
To select the port for MIDI communication, press the MIDI switch until the [MIDI>SETUP] screen
appears. Then select the port for [Gen.Rx] and/or [Gen.Tx] from either MIDI or TO PC.
The MIDI channels assigned to Gen.Rx and Gen.Tx function serve as a device ID number of the
WR-DA7 during reception or transmission of MIDI data. (Select OMNI to receive messages on all
MIDI channels.) For selecting the MIDI channels, press the MIDI switch until the MIDI SETUP
screen appears. Then, select a channel for Gen.Rx or Gen.Tx.
To control external equipment using MIDI Machine Control commands, set the MMC port to MIDI
and assign a MIDI channel. The MIDI channel needs to be the same as the external equipment
being controlled. To make the setting, press the MIDI switch until the MIDI SETUP screen appears.
Then, set up the MMC port and CH (MIDI channel).
Timecode
The WR-DA7 can record and playback automation in synchronization with external timecode. The
WR-DA7 can be synchronized to MIDI timecode (MTC), MIDI clock, and SMPTE timecode (using
the option card WR-SMPT). To select the timecode settings, press the AUTOMATION button until
the SETUP screen appears. Select the appropriate timecode from the TIME BASE area in
Automation EXECUTE window, using the parameter dial select MTC, MIDI CLK, or SMPTE then
push the ENTER key.
When MTC is used, select a port to be used for receiving the MIDI data. The MTC receive port can
be selected by pressing the MIDI switch until the MIDI SETUP screen appears. Then, select the
MTC port from MIDI or TO PC.
8
Tandem connection
Make all connections with the mixers turned OFF. You will need the following cables and cards:
(2) WR-TNDM cards, (1) Tandem cable (part # DA/DB-DB: Available in the USA), (1) MINI DIN 8Pin Serial cable (Macintosh Printer Cable), or (2) MIDI cable, (1) 75 ohm BNC-BNC wordclock
cable (part # DA/BNC: Available in the USA). Set up the consoles as master and slave and make the
tandem connections for the mixers accordingly.
MASTER: When used with the tandem master unit.
SLAVE: When used with the tandem slave unit.
To connect two WR-DA7 mixers in Tandem, install a WR-TNDM card in Slot 3 of each mixer (with
the mixers powered OFF).
Select MASTER/SLAVE on the front panel of each WR-TNDM card.
For proper wordclock synchronization between the two mixers, connect the WORD CLOCK OUT
terminal of the master unit to the WORD CLOCK IN terminal of the slave unit (75 ohm terminate
ON). To set the wordclock of the slave unit, press the D-I/O switch until the INPUT SETUP screen
appears. Then, set the SOURCE SELECT to WCK IN.
To establish communications between the Tandem mixers connect the specified serial cable
(Macintosh cross cable printer cable) or MIDI cable between the RS-422/485 and MIDI ports on
each of the mixers (TO PC or MIDI IN/OUT) must be selected to establish communications.
Communication setting are selected by pressing the D-I/O switch to display the TO SLOT screen of
D-I/O page then select the port from either TO PC or MIDI. In the case of TO PC connection, the
setting should be set so that the baud rates of the master and slave units are set the same on each
of the mixers (a baud rate of 125k is recommended). For baud rate setting, press the MIDI switch
to display the MIDI SETUP screen then select the necessary baud rate.
To establish tandem connections, press the D -I/O to display the TO SLOT screen of D-I/O and
switch the TANDEM setting to ON in Slot 3.
Press the MIDI button in the Set Up section on the TopPanel of the DA7 to select the MIDI SET UP
screen. In the PORT SELECT Area of the SERIAL I/O SETUP section, select TO PC. Set the BAUD
RATE for both consoles to 125K by highlighting the area with cursor and using dial to select the
rate. In the MIDI SETUP area, make sure the MIDI channels are set to the SAME channels for
Gen.Rx/Gen.Tx for BOTH consoles. Set Gen.Rx/Gen.Tx PORT to TO PC.
Press the D-I/O to display the TO SLOT Window. If TANDEM is not selected in the
NORMAL/INSert/TANDEM area, select it. Below the “SLOT 3 TANDEM” area, make sure TANDEM
is set to ON. Select AUTO in the OFFSET DELAY section. Make sure the PORT SELECT is set to TO
PC. The CONNECT area will read SLOT NG or DATA NG until the SLAVE console is configured.
On the Slave console, follow the same procedures. The CONNECT area in the TO SLOT window
will read SLOT NG or DATA NG until data is sent between the consoles. Turning a channel to ON
will initiate the data flow, and the CONNECT prompt in the D-I/O TO SLOT screen will then read
OK on both DA7s (this can take up 5 seconds).
2.3 ADAT, BRC
Connections
To connect an ADAT with the WR-DA7 digitally, the WR-ADAT option card is needed to connect the
9
optical cables. Install the card (with the mixer turned OFF) and screw the option card securely
into place to ensure proper grounding. To use the ADAT’s DIGITAL INPUT press the DIGITAL IN
button on the ADAT to display DIGITAL IN. (Do not switch the DIGITAL I/O button on the BRC to
ON, this is for transferring data between ADATs and may cause unsuspected results.)
To select the ADAT’s wordclock source press the SET LOCATE and DIGITAL IN simultaneously, the
ADAT will display ‘int’ for internal word clock or ‘digi’ for external word clock.
To connect multiple ADAT units, each unit is required to make ID setting. The ID order of the
ADAT are set up automatically according to how the sync cable are connected, starting with 1, in
the order of ADAT SYNC cable connections from SYNC OUT to SYNC IN. (The same ID is used
even when the BRC is connected.)
The ADATs must be powered-up before the BRC. The BRC should be turned on last.
Wordclock
If the ADAT is being used as the wordclock master set the ADAT wordclock to INT. The WR-DA7
functions as an ADAT SLAVE. The WR-DA7 wordclock settings can be set by pressing the D-I/O
switch to display the INPUT SET window of the D-I/O setup section. Then; the SOURCE SELECT is
used to select the slot where the WR-ADAT card is inserted. Cursor to that Slot and press Enter.
LOCK should be displayed in the adjacent window.
When the ADAT and the BRC are in the wordclock master mode, the sampling rate is determined
by selecting the Fixed Mode to 48kHz.
To set the sampling rate at 44.1kHz, select the Variable Mode and press the PITCH DOWN switch
on the front panel. Make the setting -147 cent (‘44.1’ display).
For the ADAT-XT, this setting is done with the CLOCK SELECT switch on the front panel and the
ADAT is set to INT clock.
To use the WR-DA7 as the wordclock master, press the CLOCK SELECT switch on the front panel
of ADAT XT to set up the ADAT XT to DIG to slave to an external clock source. When using a BRC
as ADAT master controller it is recommended that the BRC be set to slave to the DA7. To do this
press the Edit button then the External Sync button on the BRC and select 48 kHz input using the
arrow keys. Press the Edit button to exit this mode. Make sure the EXTERNAL SYNC mode is
selected (the external sync button will light green).
MIDI
To use the ADAT’s MMC operations from the DA7 with a BRC, it is necessary that the transmitting
MIDI channel of the WR-DA7 match the MIDI channel of MMC to be received on the BRC.
For MIDI setting on the BRC, press the MIDI/UTIL to display #11:
MIDI Device screen and set up the value of (MIDI channel of the
MMC command to be output from the WR-DA7) – 1.
Set up ‘ALL’ if it is necessary for the BRC to receive the MIDI messages from other MIDI equipment.
When a MIDI message is received at the MIDI IN terminal of the BRC it is immediately transferred
as a through output from the MIDI OUT terminal. To send MIDI data through the BRC, press the
MIDI/UTIL switch several times on the front panel of the BRC to display the 1:MIDI ECHO screen,
then select ‘ON’ using the arrow keys.

To receive a digital signal on the DA-98, 88, or 38, press the DIGITAL IN switch on the front panel
to select the ‘DIGITAL IN’ indicator.
When multiple DA98, 88, or 38s are connected, set the machine ID to ‘1’ (‘0’ in the case of DA88s) on the first unit (master unit). The machine IDs of the slave units should be set sequentially,
starting with ‘2’ subsequent to the units connected using the PW-88S Sync cables.
The machine ID for the DA-88 is the number added with (ID No. of
the rear panel switch) + 1.
When multiple DA98, 88, 38s are connected using the PW-88S Sync cables, the terminator included
with the Sync cables should be connected to the Sync OUT terminal of the last device.
Wordclock
When the DA-98, 88, or 38 is used as the wordclock master, the wordclock for the DA-98, 88, or 38
is set to ‘INT.’ The Wordclock selection is made by pressing the CLOCK switch on the front panel
to select ‘INT.’
To set the clock selection to INT, WORD, or VIDEO press the CLOCK
switch on the front panel of the DA-98, 88, and 38, the machine IDs
of the DA-98, 88, and 38 are required to be set as
specified below.
DA-98, 38: ID=1
DA-88: ID=0
To use a DA-88 as the wordclock master, connect a 75 ohm BNC to BNC cable from the WORD
SYNC OUT terminal of the DA-88 to the WCK IN terminal of the WR-DA7. Then press the D-I/O
switch of the WR-DA7 several times in order to display the INPUT SET screen of the D-I/O window.
Then, select the SOURCE SELECT to ‘WCK IN.’
11
12
When the DA-98 or 38 is the wordclock master, the slot where the WR-TDIF card is inserted can be
selected as the wordclock source, in addition to the above-mentioned WCK IN. For WR-DA7 wordclock setting, press the D-I/O switch several times to display the INPUT SET screen of the D-I/O
window. Then, select the SOURCE SELECT to the SLOT where the WR-TDIF card is installed.
The sampling rate settings for the DA-98, 88, 38 is dependent on the format of the tape being
used. Therefore, the sampling rate is automatically selected according to the sample rate on the
tape.
When the WR-DA7 is the wordclock master, the BNC cable should be connected from the WORD
CLOCK OUT terminal of the WR-DA7 to the WORD SYNC IN terminal of the DA-98 or 38. Select
WORD by pressing the CLOCK switch on the front panel of the DA-98 or 38.
When Connecting a DA-88 the WR-DA7 must function as the slave unit.
MIDI
For MMC control from the WR-DA7 to the DA-98, select Menu Group 3 in the DA-98 screen and
select the Ctrl Prt (Control Protocol) to ‘MIDI.’
For the MIDI ID of MMC being received on the DA-98, select Menu Group 7 in the DA-98 screen
and set the MIDI ID to the same number of the MIDI channel of the MMC to be sent from the WRDA7.
Install the SY-88 Sync board to perform MMC operation from the
WR-DA7 to the DA88.
For SY-88 Sync board setting, set the MODE dip switch 2 on the rear panel at 0 (OFF) so that control from external equipment can be accomplished through the MIDI port.
Timecode
When playing back the timecode recorded on the tape from the DA-98, select Menu Group 5 in
the DA-98 screen and set Tape (ABS) with OutTc Src.
To generate the MTC output from the DA-98, select Menu Group 7 on the DA-98 screen and set
the output to ‘ON’ with MTC Out. To generate the MTC output while the DA-98 is in FF/REW operation, set fast to ‘ON.’ To generate the MTC output when the DA-98 is stopped, set Stop to ‘ON.’
To generate the timecode output from the DA-98 in synchronization with the digital audio data,
select Menu Group 5 in the DA-98 screen and set ‘Digital’ with OutTc Tmg.
When an SY-88 Sync board is installed in the DA-88, it is possible to generate SMPTE timecode and
MTC (MIDI timecode) from the DA-88.
For proper SY-88 Sync board setting, set the MODE dip switch 6 on the rear panel to 1 (ON) so
that the timecode recorded on the tape of the DA-88 can be converted to MTC.
If the MODE dip switch 6 is set to 0 (OFF), the timecode received in the TIME CODE IN terminal
of the DA-88 is then outputted after being converted to MTC.
To generate timecode from the DA-88 in synchronization with the digital audio data set the MODE
dip switch 5 on the SY-88’s real panel to 0 (OFF).
13
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 ‘2TR IN A.’
To record and playback using the WR-DA7 as the wordclock master and the DAT as the slave, connect 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 DA98, 88, or 38 is set to ON, each unit works as a slave unit to the DTP and all other units run in synchronization with the DTP.
When the DTP is used as the MIDI interface with MMC from the WR-DA7 for the ADAT or the DA98, 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).

3. WR-DA7 system applications
3.1 Example of systems for ADAT (1 unit) (When a timecode is recorded on a tape track)
This system is used to record the SMPTE timecode on track # 8 of an ADAT. This timecode will be
used as the timecode reference for automation.
Method of connection
With the mixer powered ‘OFF’ Insert the option card WR-ADAT (Slot 1) and WR-SMPTE in the dedicated slot of the WR-DA7 and firmly fasten them to the mixer using the supplied screws.
Connect the WR-ADAT card of the WR-DA7 to the DIGITAL IN/OUT terminal of the ADAT using an
optical cable and press the DIGITAL IN switch on the front panel of the ADAT to select the digital
input mode.
The timecode is transferred by using the 8th Channel’s OUTPUT (RCA Pin Jack) of the ADAT
analogs output to the SMPTE IN (XLR: 1,3-GND, 2-SIGNAL) of the WR-DA7 using the (optional)
WR-SMPT installed.
