OPTION SLOTS
There are six slots on the rear panel for installing option cards. The first four slots from the left hand
side are for general purpose interface cards such as the IB-805R (RS422 interface) or the IB-806B
(Biphase interface). The fifth slot is for a digital audio interface card such as the IB-D8TIF (TDIF
interface), IB-D8MA24 (AES/EBU interface) or IB-804A (ADAT interface). The final slot is for the
connector to the Tascam MU-8824 Meter Bridge (this is part of the IB-D8TIF option card).
There are two more slots available for installing the analog option cards IB-D8AD (8-channel analog
input) and IB-D8DA (8-channel analog output).
AKAINET CONNECTOR
This connector is used to connect the DD8 to the DL1500 Remote Controller
TERMINATOR SWITCHES
These switch selects 75
Ω
termination for the SYNC connector for use with video sync signals
and 50

SYNC CONNECTOR
This BNC can accept either TTL wordclock or video sync signals (such as ‘black and burst’
house sync signals) and is used to synchronise the DD8 to an external clock source.
EXPANSION CONNECTOR
This connector is used to attach the optional RC15 User Assignable Remote Controller.
SCSI-B ID SWITCHES
These DIP switches are not in use at the moment (Note that this switch has no effect on the
SCSI-A bus).

This 50-pin Amphenol connector is used to connect external SCSI drives to the DD8.
GROUND TERMINAL
This terminal is provided to allow you to earth the DD8 in the event of ground loops.

PRE-READ LEVEL
This control is used to adjust the level of the oscillator signal that will be generated at the pre-
read output connector.
