192 I/O Front Panel
The 192 I/O has the following front panel fea-
tures:
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 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, that can
be 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz,
176.4 kHz, or 192 kHz. The sample rate can be
set when you create a new session, or in the
Hardware Setup or Playback Engine dialogs if no
session is open.
Loop Master LED
The LOOP MASTER LED indicates which HD au-
dio 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.
