Powering Up Your System
In order for Pro Tools to communicate properly
with audio interfaces and other peripherals, it is
important that you start up and shut down your
system in the following order:
Power up your system in this order:
1 Turn on your Pro Tools hard drives.
2 Turn on synchronization or other MIDI pe-
ripherals or interfaces.
3 Turn on your 192 I/O and any other Pro Tools
audio interfaces. On power up, the status LEDs
will flash. Wait at least fifteen seconds for the
192 I/O to initialize, and the status LEDs to stop
blinking and stay lit on any and all audio inter-
faces. If properly connected, the ring around the
power switch will be orange while the computer
is powered down.
4 Turn on your computer. When the computer
boots, all power LED rings on HD I/O should
switch to green. This signifies that the HD I/Os
are properly connected to HD cards or other HD
I/Os in your system.
MIX-series audio interfaces will not be available
until they have been made active in the Hard-
ware Setup dialog. See the
Getting Started with
HD
Guide for info.
Power down your system in this order:
1 Quit Pro Tools.
2 Shut down the computer.
3 Power off your audio interfaces.
4 Turn off any synchronization, MIDI, or other
peripherals or interfaces.
5 Turn off your drives.
Making Signal Connections to
the 192 I/O
Depending on how you plan to use the 192 I/O,
the way you connect it to your studio will vary.
Setting Up Your Studio
The following diagrams provide general sugges-
tions for connecting studio gear to your system.
Figure 1 on page 14 illustrates a studio setup
with the 192 I/O connected to a mixing console,
with effects and other gear routed into the con-
sole as well.
Figure 2 on page 15 diagram shows a setup with-
out a mixer, where effects and monitoring gear
are connected directly to the 192 I/O.
