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.

Method of connection

With the mixer powered OFF insert the option card WR-ADAT in Slot 1, 2, 3 of the WR-DA7 and fas- ten them to the securely using the 4 screws.

Connect the WR-ADAT card in the WR-DA7 to the DIGITAL IN/OUT terminals of the ADAT using an optical cable and press the DIGITAL IN switch on the front panel of each ADAT to set up the digital input mode.

The BRC functions as the wordclock master. Connect the WORD OUT of the BRC to WORD CLOCK IN of the WR-DA7 using a BNC cable and set the WR-DA7 wordclock termination to 75 Ohm=ON.

For MIDI connection, connect the WR-DA7 to the MIDI IN/OUT of the BRC using a MIDI cable. The MMC and MTC functions are now available.

For the timecode, MTC is received using the MIDI connection. (Using the option card WR-SMPT, it is possible to receive the SMPTE timecode. The SMPTE OUT (Phone Jack) of the BRC is connected to the SMPTE IN (XLR: 1,3-GND, 2-SIGNAL) of the WR-DA7.)

WR-DA7 setting To use the WR-DA7 as a slave unit, set the SOURCE SELECT to ‘WCK IN’ in the INPUT SET screen. (For synchronization with the ADAT card source, set SOURCE SELECT to ‘SLOT1.’)

For MMC, set MMC PORT to ‘MIDI’ in the MIDI SETUP screen. The MIDI channels should be set to the same MIDI channel of the MMC being received on the BRC.

To receive MTC on the DA7, set the MTC PORT to ‘MIDI’ in the MIDI SETUP screen of the WR- DA7.

To have the MTC read out on the LCD screen, set the TIME BASE to ‘MTC’ in the EXECUTE screen of AUTOMATION SETUP.

(For SMPTE timecode using the optional WR-SMPTE card, set the TIME BASE to ‘SMPTE.’)

ADAT setting

For ADAT wordclock setting, connect a Sync cable from the BRC and turn on the power supply. At that time, the setting is automatically set to ‘EXT’ and the ADAT works as a slave to the BRC.

The ADAT ID numbers are automatically set from 1, in the sequential order of the SYNC cable con- nections from SYNC OUT to SYNC IN.

The power supply of each ADAT should be turned on in the sequential order, starting with the last unit located at the end of SYNC cable connections to the first unit. Finally, turn of the power sup- ply of the BRC.

The audio input of the ADAT needs to be selected into the digital input mode. Press, the DIGITAL IN buttons on the front panel of each ADAT being used.
