Mbox 2 Mini Getting Started Guide30
Mix (Ratio) Control
Mbox 2 Mini gives you the ability to monitor 
your analog input signals while recording, with-
out the delay incurred by A/D/A converters and 
host-based processing.
This zero-latency analog monitoring is con-
trolled with the Mix knob, which you can use to 
blend and adjust the monitor ratio between 
Mbox 2 Mini analog inputs and Pro Tools play-
back.
To listen to just the source input signal, turn the 
Mix knob fully left to Input. To listen to 
Pro Tools output only, turn the knob fully right 
to Playback.
The output from the Mix control is routed di-
rectly to the Mon Out (Monitor Outputs), and is 
mirrored in the Headphone output.
This ability to blend and control the relative lev-
els of Pro Tools playback and latency-free live 
analog inputs can be particularly effective when 
overdubbing. 
USB LED
The USB LED indicates that the Mbox 2 Mini 
has received power from its USB connection. 
Once the USB light is on, audio can pass in or 
out of the system.
Input 1 Gain Control
This knob adjusts the input gain level of the In-
put 1 Mic or Line/DI input, depending on which 
input is enabled by the back panel Mic/DI 
switch.
Input 2 Gain Control
This knob adjusts the input gain level of the In-
put 2 Line/DI input.
