Connecting PRE to a Pro Tools
System
Audio Connections
PRE must be physically connected to an audio
interface (such as HD I/O or 192 I/O) in your
Pro Tools system.
To connect a PRE to a Pro Tools system:
Connect PRE outputs to analog inputs on
your audio interface. (For example, to connect
PRE to an HD I/O, use a DB-25 cable to connect
the PRE outputs to the Analog Inputs on the
HD I/O; for a 96 I/O, use a DB-25 to TRS cable.)
For installations with multiple PREs, repeat this
step.
MIDI Connections
The following are basic instructions for connect-
ing your PRE to a MIDI interface (such as an
M-Audio MIDI Sport) for remote control.
Before you connect PRE MIDI Ins and Outs, con-
nect and configure your MIDI interface accord-
ing to the manufacturer’s instructions.
To connect a PRE to a MIDI interface:
1 Connect a MIDI cable between the MIDI Out
port on your PRE and the MIDI In port on your
MIDI interface.
2 Connect a MIDI cable between the MIDI In
port on your PRE and the MIDI Out port on your
MIDI interface.
3 For additional PREs, daisy-chain them by con-
necting the MIDI Out port on the first PRE to
the MIDI In port of the second PRE, and so on.
For multiple PRE MIDI cabling considerations,
see “Installations with Multiple PREs” on
page 19.
Setting the PRE MIDI Channel
To set the global receive/transmit MIDI channel:
1 On the PRE front panel, press the MIDI Chan
switch so the LED lights.
The Gain/Param display displays the current
MIDI channel (1–16).
2 Turn the Gain/Param control clockwise to in-
crement MIDI channel numbers, or counter-
clockwise to decrement channel numbers. (The
MIDI channel will be set once you stop moving
the control; you do not need to press an Enter
switch to set the channel.)
3 To exit MIDI Channel mode, press the MIDI
Chan switch again.
4 Repeat the above steps for additional PREs.
For each PRE output, note the respective au-
dio interface input channels, as these will be
the physical inputs you map PRE outputs to
in Pro Tools. For example, PRE outputs 1–8
attached to a standard HD I/O map to ana-
log inputs 1–8; however, PRE outputs 1–8
attached to the second A/D card on a
HD I/O represent analog inputs 9–16.
