Mbox 2 Pro Setup Guide30
The Mbox 2 Pro front panel provides the fol-
lowing:
Power LED
The Power LED indicates that the Mbox 2 Pro is
powered on.
Ext (External) Clock LED
The External Clock LED lights to indicate that
either S/PDIF or Word clock is the current
Pro Tools clock source. When unlit, this LED in-
dicates Internal clock.
MIDI Activity LED
This LED lights to indicate Mbox 2 Pro is receiv-
ing or sending MIDI.
Headphone Outputs
Mbox 2 Pro provides two 1/4-inch, stereo head-
phone outputs, A and B, each with its own level
control. Headphones mirror the Monitor out-
puts, by default (usually your main Pro Tools
Analog 1–2 outputs). Headphone B can also be
configured for discrete monitoring of Pro Tools
outputs 3–4 (Analog 3–4) using the 3–4 switch.
Headphone Level
The headphone knobs adjust the output level of
their corresponding Headphone output (A or B).
3–4 Switch and LED
The 3–4 switch toggles Headphone B output be-
tween the main outputs (1–2), and output chan-
nels 3–4. When this switch is in its “out” posi-
tion, Headphone B mirrors Headphone A output
and the 3–4 LED is off. When this switch is in its
“in” position, Headphone B monitors Pro Tools
output channels 3–4.
Monitor Level
The Monitor knob adjusts the output level of
the Mon Out ports. In Pro Tools, this will be the
signal routed to Analog outputs 1–2.
48V Switch and LED
Phantom power is activated by the switch la-
beled 48V on the front panel of Mbox 2 Pro. The
LED, when lit, indicates that 48V phantom
power is active on both Mic/Line inputs. These
inputs provide phantom power for micro-
phones that require it to operate.
