02R with Two ADATs & BRC
This application shows how the 02R can be used with two Alesis ADATs and a BRC Master
Remote Control to create a 24-input, 16-track digital recording system. The 16 digital tape
returns and 24 Mic/Line inputs provide up to 40 inputs at mixdown. In addition, the 02R's
built-in automation and scene memory systems provide both dynamic and static mix
automation referenced to timecode.
Connections
• The ADAT (CD8-AT) cards 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 buttons on the ADATs to use the DIGITAL IN.
• ADAT–A is connected to Slot [1] of the 02R and the tape inputs correspond to tracks
one through eight.
• ADAT–B is connected to Slot [2] of the 02R and the tape inputs correspond to tracks
nine through sixteen.
• 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 BRC provides ADAT timecode to SMPTE timecode conversion. In addition, a
timecode offset can be specified, so the automix start time can be adjusted.
• 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 two ADATs locks to it automatically via the
9-pin sync cables. The sampling rate can be set to either 48 kHz or 44.1 kHz. Use Fixed
mode for 48 kHz and Variable mode for 44.1 kHz (using the PITCH DOWN button, set to
–147 cents. At which point "–146, 44.1, –148" appears on the display). The newer ADAT-XT
has dedicated switches for selecting these two sampling rates.
Notes
• The ADATs must be powered up before the BRC and in the following order: B then A.
This is because when the BRC is powered up it checks how many ADATs are connected,
allocates them device numbers, and automatically sets the system clock.
• 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.
