Distortion or noise when transferring via TDIF from Pro Tools 5.3 to Tascam DA-88
Performing a TDIF transfer from the 192 I/O to a DA-88 with Pro Tools 5.3 will result in full code displayed across all 8 channels on the DA-88 and distorted signal. It is possible to transfer via TDIF from the DA-88 into the 192 I/O. This problem does NOT exist with DA-98R transfers (even with the DA-98 set to emulate a DA-88).
Updating to Pro Tools 5.3r4 and higher resolves this problem. Pro Tools 5.3r4 also requires that the following software be updated to version 5.3r4: DHS.shlb, DSI.shlb, Digidesign Direct I/O, and DAE
IMPORTANT: It is also required that a 75-ohm shunt terminator be placed on the Word Sync Input of the DA-88. (The DA-88 will not lock to the Word Clock output of the 192 Digital I/O or 192 I/O without a terminator in place.) Terminating the Word Sync Input of the DA-88 can be accomplished by using a T-connector (one of the “t’s” has the terminator on it, the other the Word Clock cable from the 192/192 Digital I/O) or by using an in-line terminator.
