Introduction to the 192 I/O
®
The Digidesign 192 I/O™ 16-channel digital
audio interface is designed for use in a
®
Pro Tools|HD system.
The 192 I/O features 24-bit analog-to-digital
(A/D) and digital-to-analog (D/A) converters,
and supports sample rates of up to 192 kHz.

192 I/O Features

• 16 discrete channels of input and output,
with 4-segment LED Meters to monitor input
and output on each channel. Input and Out-
put channels can include:
• Eight channels of 24-bit D/A and A/D con-
verters for superior analog input and out-
put at sample rates of 44.1 kHz, 48 kHz,
88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz
• Ten channels of 24-bit-supported AES/EBU
I/O. Eight-channel AES/EBU I/O supports
sample rates of up to 96 kHz on all chan-
nels, and up to 192 kHz on four channels
simultaneously. Two-channel AES/EBU I/O
supports sample rates of up to 96 kHz.
• Sixteen channels of Optical I/O, through
two pairs of Lightpipe (ADAT) connectors;
one pair of optical ports can be switched to
two channels of optical S/PDIF I/O
• Two 24-bit-capable S/PDIF I/O supporting
sample rates of up to 96 kHz
• Real-time sample rate conversion on inputs of
eight channels of either AES/EBU, Optical, or
TDIF.
• External Clock input and output for synchro-
nizing 192 I/O with external 1x Word Clock
or 256x (Slave Clock) devices.
• Legacy Port for Digidesign-qualified
Pro Tools|24 MIX™ audio interfaces.
• Optional addition of cards to expand analog
or digital I/O.
• Simultaneous use of multiple Pro Tools|HD
audio interfaces to further expand system in-
put and output. For more information see the
Expanded Systems Guide.
