Output Pairs
For each Mbox Pro Monitor output pair (Moni-
tor outputs 1–2, 3–4, 5–6, S/PDIF Left and Right,
or Headphones A and B), there is a representa-
tive tab in the output pair select view. The output
pair select view lets you choose the audio source
for each Monitor output pair, and where appli-
cable, edit the audio source.
Each output pair select tab includes a drop-
down menu where you can select the audio
source you want. The sources include:
•Stereo Mix 1
•Stereo Mix 2
• Stereo Mix 3 (Available only at sample rates
at or below 96 kHz)
• Stereo Mix 4 (Available only at sample rates
at or below 96 kHz)
• Stereo Mix 5 (Available only at sample rates
at or below 96 kHz)
• Stereo Mix 6 (Available only at sample rates
at or below 96 kHz)
• Software Returns 1–2
• Software Returns 3–4
• Software Returns 5–6
• Software Returns 7–8
• Hardware Inputs 1–2
• Hardware Inputs 3–4
• Hardware Inputs 5–6
• Hardware Inputs 7–8
The available output pair audio sources can be
divided into two categories:
Stereo Mixes
A stereo mix lets you set up a custom stereo mix,
setting the desired level for each hardware input
and software return that is fed to the hardware
output pair. See the Stereo Mix section below for
details.
Direct Routes
A direct route means that the chosen signal is
passed directly to the hardware output pair. For
example, if the source for output pair 1–2 were
“Hardware Inputs 1–2,” then the signal coming
into hardware inputs 1–2 of the Mbox Pro
would be fed directly to hardware outputs 1–2.
Similarly, if the source were “Software Returns
1–2,” the signal fed from an audio host software
returns 1–2 would be fed directly to hardware
outputs 1–2.
Notes:
• The source of the currently selected tab is
displayed below the output pair select view.
See “Output Setup” on page 31.
• For Stereo Mix sources, a traditional mixer
view is displayed.
• For direct route sources, a view with meters
is displayed, and the input source and out-
put destination are highlighted.
• You can drag and drop the tabs to reorder
them if you want.
Notes on output pairs that are designated as
control room outputs:
• If an output pair is a designated control
room output (see “Control Room Assign-
ment” on page 32), a speaker icon will ap-
pear in the upper right corner of the tab.
Click the speaker icon, or double click the
tab, to make the associated output pair the
active control room speaker pair.
