Appendix F
Installation and Connection of
Optional I/O Cards
There are several optional cards available
for the Digital 8•Bus which you can install into
the card cage in the rear panel of the console.
These cards provide additional inputs and
outputs for specific applications, or additional
digital signal processing power for effects.
AIO•8
This card provides 8 analog line-level inputs
and 8 analog line-level outputs. Connections are
made through two 25-pin D-Sub connectors. You
can install this card in any of the Tape In/Out
slots, or in the ALT I/O slot.
Connections for AIO•8
Refer to Figure F-1 for the pin-out diagram
of the 25-pin connectors.
DIO•8
This card provides 8 digital inputs and 8
digital outputs. Connections are provided in
both ADAT Multichannel Optical Interface and
Tascam T/DIF-1 formats. You can install this
card in any of the Tape In/Out slots, or in the
ALT I/O slot. You can mix any combination of
the AIO•8 and DIO•8 cards in the Tape I/O
slots to suit your particular application.
You can configure the card in software and
select which I/O connector you want to use.
Refer to the section “Configuring Digital I/O” in
Chapter 3 for more information.
Connections for ADAT
The connection for ADAT is made with a
fiber optic cable, sometimes referred to as a
“lightpipe.” This connector provides 8 channels
of bidirectional digital audio. You can purchase
this cable from your Alesis dealer.
Connections for DA-88
The connection for T/DIF-1 is made with a
25-pin D-Sub connector. This connector
provides 8 channels of bidirectional digital
audio. This connection requires a proprietary
cable made by Tascam (Part Number PW-88D).
AES/EBU Card
This card provides 8 digital inputs and 8
digital outputs in the AES/EBU standard
format. Connection is made through a single
25-pin D-Sub connector. You can install this
card in any of the Tape In/Out slots, or in the
ALT I/O slot.
Connections for AES/EBU
AES/EBU is a standard two-channel digital
protocol used for long balanced cable
applications. Thus, each conductor actually
transmits two channels of digital audio data.
Refer to Figure F-2 on the next page for the
pin-out diagram of the 25-pin connector.
