02R with Two ADATs (Timecode on Tape Track)
This application shows how the 02R can be used with two Alesis ADATs to create a 24-input,
16-track digital recording system. As shown in Figure 7, track eight of ADAT–A has been
striped with SMPTE timecode. This is then fed to the 02R’s SMPTE TIMECODE input
using a phone jack to phono cable.
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 ADATs 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. These tape inputs correspond to tracks one
through eight.
• ADAT–B is connected to Slot [2] on the 02R. These tape inputs correspond to tracks
nine through sixteen.
• ADAT track eight is striped with SMPTE timecode. ADAT track eight analog out (phone
jack) output is connected directly to the 02R’s SMPTE TIMECODE input (phono).
02R Wordclock Setup
ADAT (CD8-AT) cards are installed in Slot [1] and Slot [2], so any one of the first 16 tape
inputs can be selected as the wordclock source on the DIGITAL I/O menu.
ADAT Wordclock Setup
ADAT–A should be set as wordclock master. To confirm this, press the SET LOCATE and
DIGITAL IN buttons together. The display should show “int”, meaning internal wordclock.
The ADAT 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
• Press the DIGITAL IN button on the ADAT to use the DIGITAL INPUT.
• ADAT–B must be powered up before ADAT–A, because when ADAT–A is powered up it
checks how many ADATs are connected, allocates them device numbers, and
automatically sets the system word clock. ADAT–A works as Control Master.
