4 1. Intr oduction This Application Guide supplies examples for interfacing the WR-D A7 with commonly used peripheral recording equipment. This guide’s diagrams provide the necessary connections and the methods for establishing proper system operation.
5 2. Notes for connections with peripheral equipment 2.1 W ordclock The WR-D A7 as wordclock master The D A7 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.
6 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.
7 T andem connection Make all connections with the mixers turned OFF . Y ou will need the following cables and cards: (2) WR- TNDM cards, (1) T andem cable (part # D A/DB-DB: Available in the USA), (1.
8 2.3 AD A T , BR C Connections T o connect an AD A T with the WR-D A7 digitally , the WR-AD A T 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.
9 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. T o 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.
10 SYNC OUT terminal of the D A-88 to the WCK IN terminal of the WR-D A7. Then press the D -I/O switch of the WR-D A7 several times in order to display the INPUT SET screen of the D -I/O window .
11 2.5 D A T (with AES/EBU or S/PDIF I/O) T o record and playback using the D A T Recorder as the wordclock master and the WR-D A7 as a slave, connect the D A T to the REC OUT and 2TR IN terminals of the WR-D A7.
12 Normally , a Macintosh computer has two serial ports: modem and printer port. R AMSA MA X soft- ware permits connection of either of these ports to the WR-D A7.
13 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-D A7 connected.
