M48 48V Power Supply
Hookup Diagram
The M48 48V Power Supply is the perfect solution for anyone using a condenser microphone (or other
equipment) that requires phantom power. Let’s take a look at the hookup diagram.
Start by turning the down the main output level of the audio interface. In this example it’s a Mackie Big Knob
Studio+. Next, connect a condenser microphone to the M48’s input jack using a balanced XLR cable. Now,
you will want to connect a balanced XLR cable from the M48’s output jack to the audio interface’s input jack.
Finish up by slowly raising the level of the audio interface’s output knob.
Note: While an audio interface may be the most common use, you could connect a mixer in lieu of an audio
interface to the M48.
Note: If the audio interface or mixer has built-in phantom power, do not engage it while using the M48!
