INSTALLING DIGITAL INTERFACE BOARD
The IB-D8TIF TASCAM digital interface board needs to be installed in the DD8 to transmit or
receive digital audio in TASCAM format (8-channel). It also provides the interface to connect
with the TASCAM’s MU-8824 Meter Bridge on a separate board.
The IB-D8MA24 multi-channel AES/EBU digital interface board needs to be installed in the DD8
to transmit or receive digital audio in AES/EBU format (8 channel).
The IB-804A ADAT interface board needs to be installed in the DD8 to transmit or receive digital
audio in 8-channel ADAT format.
Remove the connector cover (5th slot from the left on the rear panel) for the digital interface
board by loosening the two screws on the rear panel. Remove the board holder by loosening the
two screws. Place the digital interface board in place and connect its connector to P209 on the
Mother P.C. Board. Fix the board with the two screws on the rear panel that have been removed
previously. Then replace the holder and tighten it with the two screws.
When the IB-D8TIF is installed, remove the 6th cover from the left on the rear panel for the Meter
Bridge interface board. Place and secure the interface board into the slot as done for the main
interface board.
Note: Only one digital interface board can be installed on the DD8 at a time.

The IB-805R RS422 interface board, when installed, allows the DD8 to be controlled using
Sony™ P2 protocol via the RS422 port.
The IB-806B Biphase interface board, when installed, allows the DD8 to be synchronised via
biphase pulses.
The IB-808G GPI/O interface board, when installed, allows the DD8 to accept controls via GPI/
O port.
Remove the two screws from the board holder. Then remove the connector cover (1st to 4th slot

on the rear panel. Place the interface board in place and connect its connector to the appropriate
connector (P205 to P208) on the Mother P.C. Board. Fix the board with the two screws on the
rear panel that have been removed previously. Replace the board holder with two screws.
