Connecting Keyboards and Mixers
To use a keyboard or mixer with Mbox 2:
1 Plug your keyboard, mixer, or other audio 
source into either the Input 1 or Input 2 Line 
(TRS) inputs on your Mbox 2. If your source is 
stereo (such as a stereo keyboard or the stereo 
output from a mixer), connect the left channel 
(often the white plug) to Input 1, and right 
channel (often the red plug) to Input 2.

Mic by pressing the Mic/DI switch until the Mic

Source selector and Gain control for Input 1
When you record a guitar (or any mono in-
strument that uses only one source input), 
you will hear the sound in only one side of 
the stereo field. Pushing the “mono” button 
on the front of the Mbox 2 brings the sound 
from one side of the stereo field to both 
sides. The Mono switch does not affect the 
audio being recorded. It only affects how 
you hear your input to the Mbox 2.
