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 sig- nals with a

WR-AESS: Select the switch (AES/EBU, S/PDIF) on the card, according to the devices 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 connection

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 8-Pin Serial cable (Macintosh Printer Cable), or (2) MIDI cables, (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 accord- ingly. MASTER: When used with the tandem master unit.

2.3 ADAT, BRC Connections To connect an ADAT with the WR-DA7 digitally, the WR-ADAT option card is needed to connect the 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 t

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. Timecode To generate MTC from the BRC, press the EDIT switch and then press the GEN SYNC switch until the MIDI screen appears. Select MTC, and turn the GEN SYNC switch to ON

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.’ 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 word- clock setting, press the D-I/O switch several times to display the INPUT SET

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, con-

Normally, a Macintosh computer has two serial ports: modem and printer port. RAMSA MAX soft- ware permits connection of either of these ports to the WR-DA7. To control one WR-DA7, the modem port is normally used. To control two WR-DA7s, connect the WR-DA7 (serving as the mas- ter) to the modem port and the other one (serving as the slave) to the printer port. For tandem communication between the two WR-DA7s, a MIDI cable must be connected from MIDI IN on one WR-DA7 to MIDI OUT on the other. M

Set the OMS as follows: Start the OMS setup application. If the OMS is not installed, it can be downloaded from the manufactures web-site. Select [OMS MIDI Setup] in the Edit menu. Select the port (normally, the printer port) in which there's no WR-DA7 connected. (In this case, de-select [Modem] and [Run MIDI In background].) If OMS is started for the first time, the MIDI devices connected to the computer must be rec- ognized by the OMS. Connect the MIDI devices being used to the printer port

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 dedi- cated slot of the WR-DA7 and firmly fasten them to the mixer using the supplied screws. Connect the WR-ADAT card of the

3.2 Example of systems for ADAT (3 units) and BRC This system is configured using 3 ADATs and a BRC connected using the ADAT Sync cables and the three ADAT units are being remote-controlled from the BRC. In addition, it is possible to perform automation synchronized to timecode (MTC or SMPTE) from the ADAT using the MIDI out of the BRC, and having the ADAT controlled by MMC from the WR-DA7.

During ADAT playback there will be no playback while ALL INPUT is ON. ALL INPUT must be turned OFF. BRC setting Select the Fixed Mode when the BRC is used as a word clock master and 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 make setting at -147cent ( ‘44.1’ display). For MTC setting, set MIDI in the GEN SYNC setting at ‘MTC’ and turn on the GEN SYNC switch.

For proper tandem connections, select the TANDEM setting to ‘ON’ in the TO SLOT screen of the D-I/O Input Setup Section. To operate MMC, set the MMC PORT to ‘MIDI’ in the MIDI SETUP screen of the TANDEM MASTER unit. In this case, the MIDI channel of MMC should be set at the same MIDI channel of MMC to be received on the BRC. To send/receive the MIDI messages, set the PORT of Gen.Rx and Gen.Tx to ‘MIDI’ in the MIDI SETUP screen. For the TANDEM SLAVE unit, set the SEND/RECEIVE of the various
