ANWENDUNGS-BEISPIELE FÜR 02R
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) card must be screwed securely into the slot 1 in place. Do not leave the screws out after installation as the card will not be grounded correctly. The ADAT's eight tracks connect to 02R slot [1], tape inputs one through eight.

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 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.

[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. Use Fixed mode for 48 kHz and Variable mode for 44.1 kHz (using the PITCH DOWN button, set to -146 cents. At which point 44.1 appears on the display).
The newer ADAT-XT has dedicated switches for selecting these two sampling rates.

[02R Wordclock Setup]

On the DIGITAL I/O menu, the wordclock source should be set to W.CLK.

[Notes]

Press the DIGITAL IN button on the ADAT to use the DIGITAL INPUT.

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.

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.
