This chapter describes the front and back panel features of the 192 I/O.
192 I/O Front Panel
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 con-
nected 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 Hard-
ware Setup or Playback Engine dialogs if no ses-
sion is open.
See the Pro Tools|HD Getting Started Guide for complete system installation and configuration instruc-
tions.
If you are adding the 192 I/O to an existing system, see the Expanded Systems Guide.
