Enabling Phantom Voltage
On the MixPre-3, phantom power is off, but may be turned on when using 
microphones that require phantom power. When on, phantom powering is a 
fixed DC voltage of 48 volts. 
 
i
This voltage is resistively applied to pin 2 and pin 3 of an input’s XLR-3F connec-
tor, relative to pin 1. In this configuration, there is no voltage difference between 
signal pins 2 and 3.
To turn on phantom voltage:
1.  Press in the fader for the corresponding XLR input (1-3). 
2.  Tap PHANTOM. This toggles the setting between Off and 48V.
