Chapter 2: HD I/O Overview

HD I/O Back Panel
Although the HD I/O is a sixteen-channel audio
interface, it has up to 94 inputs and outputs
available through its various back panel connec-
tors.
HD I/O comes in three standard configurations:
• 8 x 8 x 8 analog and digital in and out
• 16 x 16 analog in and out
• 16 x 16 digital in and out
Input and Output Cards
The HD I/O features four bays for HD I/O Ex-
pansion cards. With the standard 8 x 8 x 8 con-
figuration, bays 1–3 contain Analog In, Analog
Out, and Digital I/O cards, respectively. The
fourth bay (as shown in this 8 x 8 x 8 configura-
tion) is an expansion bay, for which you can
purchase an additional Expansion I/O card of
your choice.
By installing an optional AD Expansion card,
DA Expansion card, or Digital Expansion card,
you can add even more I/O capacity (up to a
maximum possible 110 inputs and outputs). See
Chapter 5, “Adding or Removing I/O Cards.”
Analog Input
The HD I/O Analog In card contains connectors
for analog audio input with 24-bit, 192 kHz A/D
converters. Input is provided through two dis-
crete DB–25 connectors (one for +4 dBu
sources, and the other for –10 dBV sources).
You can connect sources at both operating levels
and choose between them from within
Pro Tools.
