Connecting a Sound System
The default monitor outputs on the back of the
Mbox Pro (Monitor outputs 1 and 2) support 1/4-
inch plugs. These connections can be balanced
TRS (Tip-Ring-Sleeve) connectors, or unbalanced
TS (Tip-Sleeve) connectors such as those on in-
strument cables. To listen to your to audio, connect
these outputs to any amplification system: pow-
ered speakers, a home stereo system, or an audio
mixer.
To connect to a sound system:
 For stereo monitoring, connect Monitor outputs
1 and 2 to the inputs of your main left and right
speakers. You can hook up more than one set of
stereo speakers and switch between them
(Speaker A, B, C switching). See “Output
Setup” on page 30.
To connect to a stereo system:
 When connecting to a stereo system, connect
the left channel of the stereo (often the white
plug) to Monitor output 1, and the right channel
of the stereo (often the red plug) to
Monitor output 2.
Monitor Outputs 1–6
Monitor outputs 1–6 can be connected to any de-
vice that has analog inputs. Use these six balanced
1/4-inch TRS outputs to feed analog devices such
as headphone amps or cue systems for discrete
headphone mixes, samplers, or a secondary re-
corder.
There are other use for Monitor outputs, such as:
• Stereo main monitors (Monitor outputs 1–2)
• Stereo/Alt monitors (Monitor outputs 3–4)
• Surround (Monitor outputs 1–6),
To connect additional Mbox Pro outputs:
 Using 1/4-inch TRS cables, connect any of the
Line Out (1–6) connectors on the back panel to
the inputs of your external devices.
Line Out connectors for monitors on Mbox Pro
Mbox Pro is capable of 5.1 surround moni-
toring complete with custom configuration
and routing controls. For more information,
see “Output Setup” on page 30.
Monitor outputs 1–6
Home stereo systems often use RCA connec-
tors. You can use an adaptor or a special ca-
ble to convert from the 1/4-inch TRS (Tip-
Ring-Sleeve) connectors used by Mbox Pro to
the RCA connectors on your home stereo.
See the
Pro Tools Reference Guide for infor-
mation on signal routing, sends and bussing.
