Two 02Rs with Four ADATs & BRC
This application shows how two 02Rs can be used with four Alesis ADATs and a BRC Master
Remote Control to create a 48-input, 32-track digital recording system. The 32 digital tape
returns and 48 Mic/Line inputs provide up to 80 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.
The two 02Rs are cascaded together using a 25-pin straight cable and two Cascade
(CD8-CS) cards, which are installed in Slot [3] of each 02R (could be Slot [4]). The
cascade connection carries the eight buses, any four of the eight AUX buses, Stereo bus, and
Solo bus. This allows both consoles to work together as one large 80-input mixing console.
The master section of 02R–B is used for monitoring and two-track operations. The studio
monitors and two-track recording equipment are also connected to this 02R.
Connections
• The ADAT (CD8-AT) and Cascade (CD8-CS) 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 the
Optical Cable. Press the DIGITAL IN buttons on the ADATs to use the DIGITAL IN.
• ADAT–A is connected to Slot [1] of 02R–A and the tape inputs correspond to tracks one
through eight. ADAT–B is connected to Slot [2] of 02R–A and the tape inputs
correspond to tracks nine through sixteen. ADAT–C is connected to Slot [1] of 02R–B
and the tape inputs correspond to tracks 17 through 24. ADAT–D is connected to Slot
[2] of 02R–B and the tape inputs correspond to tracks 25 through 32.
• The Alesis BRC Master Remote Control can control up to 16 ADATs (i.e. 128 tracks).
• 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 switches on both 02Rs 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 four ADATs follows 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: D, C, B, 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.
• The rear of the Cascade (CD8-CS) cards have an IN/OUT switch. On 02R–A is set to
OUT. On 02R–B it is set to IN.
• To generate timecode on the BRC, press the GEN SYNC button.
• The optional CD8-CS kit contains two CD8-CS cards and one 25-pin straight cable.
