Connect your Guitar and
Configure Source Input
If your setup includes pedals or other gear, it
helps to know whether the final output device is
providing an instrument- or line-level signal.
Choose and configure your input and source set-
tings accordingly. (Check the Setup Guide that
came with your system for more information.)
To connect your guitar to a Pro Tools host-based
system:
1 Do one of the following, depending on your
hardware configuration:
• If you are using an interface that has a DI
input (such as an Mbox Pro), plug your gui-
tar into an available DI input.
– or –
• If you are using your computer’s built-in in-
puts, plug your guitar into an available in-
put.
2 Make sure to use the correct input on your in-
terface. For example, on Mbox Pro, plug your
guitar into front-panel DI Inputs 1 or 2.
sTo connect your guitar to a Pro Tools|HD system:
1 Make sure you have a pre-amp (such as an Avid
PRE
®
) or similar unit connected to a
Pro Tools|HD audio interface. (Note that
HD OMNI provides built-in preamps.)
2 Plug your guitar into an available pre-amp in-
put and set its source, impedance, and other set-
tings as needed for your setup.
For example, if using a Avid PRE you can plug
your guitar directly into the front panel
Line/Inst 1 input, then set its source to Inst.
Set Hardware and Levels
After plugging in, do the following to set your
primary gain and configure your Pro Tools
hardware by watching its input indicators (me-
ters). This sets the first stage of your gain struc-
ture for Eleven.
If you use a direct box to convert your gui-
tar’s hi-impedance output to a low-imped-
ance signal, connect the direct box to a mic
or line input instead of the DI input.
Mbox Pro DI Inputs 1 and 2
Mbox Pro back-panel 1/4” inputs are
line-level only and should not be used
with a guitar.
If you use a direct box to convert your gui-
tar’s hi-impedance output to a low-imped-
ance signal, set the Line/Inst 1 input to Line
source or the equivalent on your particular
pre-amp.
