ANWENDUNGS-BEISPIELE FÜR 02R
02R with Two DA-88/DA-38


This application shows how the 02R can be used with two Tascam DA-88s to create a 24-input, 16-track digital recording system. The 16 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 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.

The Tascam digital audio cables (PW-88DL) carry the eight tape sends and returns.

DA-88-A is connected to Slot [1] of the 02R. These tape inputs correspond to tracks one through eight. DA-88-B is connected to Slot [2] of the 02R. These tape inputs correspond to tracks nine through sixteen.

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, so the 02R automix start time can be adjusted.

The 75 ohm wordclock termination switch on the back of the 02R is set to ON.

[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 DA-88-B using a PW-88S 15-pin sync cable. 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.

[02R Wordclock Setup]

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

[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 0. DA-88-B is set to MACHINE ID1. Since DA-88-A works as 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. DA-88-B does not require the SY-88 Sync Board nor does its tape have to be striped with timecode. It is synchronized to DA-88-A via the PW-88S 15-pin sync cable.

The terminator bundled with the PW-88S sync cable should be connected to the SYNC OUT on DA-88-B 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 while the power is off.

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

On the Tascam (CD8-TD) card there is a DIP switch that should be set to 16-bit. This is the initial setting, but you should confirm it. This switch is for use with Tascam High-Bit recording applications.

Tascam 25-pin digital audio cables PW-88DL (5 m) and PW-88D (1 m), and the 15-pin PW-88S sync cable are available from Tascam.
