Introduction to the 192 I/O
The Digidesign 192 I/O™ 16-channel digital audio interface is for use in a Pro Tools|HD system
and features 24-bit analog-to-digital (A/D) and
digital-to-analog (D/A) converters. The 192 I/O
supports sample rates of up to 192 kHz for superior dynamic range and low noise floor.
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 Output channels can include:
• Eight channels of 24-bit D/A and A/D converters for superior analog input and output 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 channels, and of up to 192 kHz on four channels simultaneously. Two-channel AESEBU 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 synchronizing 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 input and output. For more information see the
Expanded Systems Guide.

Power Switch and LED Ring
This button turns the 192 I/O on and off.
The LED ring around the power button will light
green to indicate that the unit has powered up
successfully and is connected to an active
Pro Tools|HD system. If the LED ring is orange,
the unit has power, but the computer it is connected to is shut down.
Sample Rate
These LEDs display the current sample rate of
the 192 I/O internal crystal oscillator: 44.1 kHz,
48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, or
192 kHz. The sample rate can be set in Pro Tools
when you create a new session, or in the Hardware Setup or Playback Engine dialogs if no session is open.
