Two 02Rs with Four DA-88s

This application shows how two 02Rs can be used with four Tascam DA-88s 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.

The two 02Rs are cascaded together using a 25-pin straight cable and two CD8-CS Cascade
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 Tascam (CD8-TD) cards must be screwed securely in place. Do not leave the screws
out after installation as the cards will not be grounded correctly.

DA-88–A is connected to Slot [1] of 02R–A and the tape inputs correspond to tracks one
through eight (Tape In 1–8). DA-88–B is connected to Slot [2] of 02R–A and the tape
inputs correspond to tracks nine through sixteen (Tape In 9–16). DA-88–C is connected
to Slot [1] of 02R–B and the tape inputs correspond to tracks 17 through 24 (Tape In
1–8). DA-88–D is connected to Slot [2] of 02R–B and the tape inputs correspond to
tracks 25 through 32 (Tape In 9–16). PW-88DL cables are available from Tascam.

The optional SY-88 Sync Board is required for DA-88–A. This enables the dedicated
timecode track, which can be re-striped at anytime, and provides SMPTE timecode and
MTC outputs. A timecode offset can be specified on DA-88–A.

02R Wordclock Setup

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

DA-88 Wordclock Setup

DA-88–A works as wordclock master. Wordclock is fed to the 02R using a BNC to BNC
cable, and to the other DA-88s using PW-88S 15-pin sync cables, available from Tascam.
The sampling rate is set when the DA-88 tapes are formatted. This can be either 48 kHz or
44.1 kHz. After formatting, the sampling rate is determined by the formatted tape.

Notes

The DA-88s must be powered up even when they are not being used. Failure to do so may
cause an intermittent pumping noise on the 02R.

DA-88–A is set to MACHINE ID to 0, DA-88–B to MACHINE ID to 1, DA-88–C to
MACHINE ID 2, and DA-88–D to MACHINE ID 3. Since DA-88–A works as the
Control Master, it should be used for synchronized transport and locate operations.

The optional Tascam SY-88 Sync Board must be installed in DA-88–A to use SMPTE
timecode and MTC. This is available from Tascam. The other DA-88s do not require
SY-88 Sync Boards and their tapes do not have to be striped with timecode. They are
synchronized to DA-88–A via the PW-88S 15-pin sync cables.

The terminator bundled with a PW-88S sync cable should be connected to the SYNC
OUT on DA-88–D to ensure reliable synchronization.

The rear panel of the SY-88 Sync Board has a DIP switch labeled MODE. Set DIP
switches 2 and 5 to ON (O). Set internal switch 8 on the SY-88 board marked S2 to ON.

To use the MTC function, the SY-88 firmware must be version 3.08 or higher.
