Mbox 2 Getting Started Guide40
Using a Mic that Has an XLR 
Connector
To use a microphone that has an XLR connector:
1 Plug your microphone cable into one of the 
Mic inputs on the back of Mbox 2.
2 Make sure nothing is plugged in to the 
Line (TRS) jack, otherwise Mbox 2 will use audio 
from the Line (TRS) input and not the Mic in-
put. 
3 Set the Source to Mic (microphone) by press-
ing the Mic/DI Source selector on the front of 
Mbox 2 until the Mic LED is lit. 
4 If your microphone requires phantom power, 
make sure the microphone is connected, then 
press the Phantom Power switch (labeled 48V) 
on the front of the Mbox 2. This switch sends 
48V to both mic inputs. The 48V LED on the 
front of the Mbox 2 will light when phantom 
power is being supplied. 
5 On the front of the Mbox 2, turn the Mix con-
trol fully left to Input.
6 On the front of the Mbox 2, carefully turn the 
Gain control to the right to increase the input 
level of your microphone signal.
7 If the incoming signal is too loud, press the 
Pad switch to engage the 20 dB pad.
