192 Digital I/O Overview
192 Digital I/O Front Panel
The 192 Digital I/O has the following front
panel features:
Power Switch and LED Ring
This button turns the 192 Digital 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 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 Digital I/O internal crystal oscillator,
which can be set to 44.1 kHz, 48 kHz, 88.2 kHz,
96 kHz, 176.4 kHz, or 192 kHz. The sample rate
is set when you create a new session, and can be
changed in the Hardware Setup or Playback En-
gine dialogs if no session is open.
Loop Master LED
The Loop Master LED indicates which HD audio
interface is the master Pro Tools peripheral.
Loop Master defaults to the first HD I/O con-
nected to the HD Core card. Loop Master will al-
ways be lit with a single interface.
