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 it’s 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 ‘V-SYNC’ 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 ‘SMPTE’ in the
EXECUTE window of Automation Setup Section
Digital Video Recorder settings: To receive AES/EBU digital audio, make the settings of ‘DIGITAL
IN’ on the LCD screen.
A ‘CHANNEL STATUS CRCC ERROR’ may be displayed during Digital
recording from the DA7.
This is; however, a message in regards to the sub-code signal, even
