02R with Video Machine, ADAT, & BRC
This application shows how the 02R can be used with a video machine, ADAT, and BRC for
audio post-production and audio sweetening, with 02R automation. Using only the SMPTE
timecode from the video machine, the BRC can generate both timecode (SMPTE or MTC)
and wordclock for the ADAT and 02R. A timecode offset can be specified on the BRC.
Connections
• The ADAT (CD8-AT) card must be screwed securely in place. Do not leave the screws out
after installation as the cards will not be grounded correctly.
• The Digital In/Out connectors on the 02R and ADAT are connected together using
Optical Cables. Press the DIGITAL IN button on the ADAT to use the DIGITAL IN.
• The ADAT's eight tracks connect to 02R slot [1], tape inputs one through eight.
• The Alesis BRC Master Remote Control can control up to 16 ADATs (i.e. 128 tracks).
• A 9-pin Sync cable for connecting the ADAT and BRC is available from Alesis.
• The 75 ohm wordclock termination switch on the back of the 02R is set to ON.
02R Wordclock Setup
On the DIGITAL I/O menu, the wordclock source should be set to W.CLK.
ADAT & BRC Wordclock Setup
The BRC works as wordclock master and the ADAT locks to it automatically via the 9-pin
sync cable. The sampling rate can be set to either 48 kHz or 44.1 kHz.
Notes
• The ADAT must be powered up before the BRC, because when the BRC is powered up it
checks how many ADATs are connected, allocates them device numbers, and
automatically sets the system wordclock.
• On the BRC, set the Clock Source to Internal. Setting it to SMPTE may cause noise.
• To generate timecode on the BRC, press the GEN SYNC button.
• On the BRC, set the DIGITAL I/O button to OFF. This function is for direct ping-pong
between multiple ADATs. If this is turned ON while connected to an 02R, bus
assignments will produce unexpected results. Press the DIGITAL IN button on the
ADAT to use the DIGITAL INPUT.
