Phantom Power
Most modern professional condenser mics require  
48V phantom power, which lets the mixer send  
 
low-current DC voltage to the mic’s electronics  
through the same wires that carry audio. (Semi-pro 
condenser mics often have batteries to accomplish  
the same thing.) “Phantom” owes its name to an ability 
to be “unseen” by dynamic mics (Shure SM57/SM58,  
for instance), which don’t need  external power and 
aren’t affected by it anyway.
The ProFX mixer’s phantom power is  
globally  controlled by the phantom power 
switch (meaning that phantom power for  
all mic inputs is turned on and off together.)
Never plug   single-ended (unbalanced)  
micro phones or ribbon microphones into  
the mic input jacks if phantom power is on. 
Do not plug instrument outputs into the mic input jacks 
with phantom power on  unless you know for certain it  
is safe to do so.
6. Line / Hi-Z Switch [ProFX8v2 / ProFX12v2]
To connect a guitar directly to the mixer without  
using a DI Box, press this switch in first; then connect 
the output from the guitar to channel 1's 1⁄4" TRS  
input. The input impedance is optimized for direct  
connection and high-frequency fidelity is assured.
In the out position, channel 1's 1⁄4" TRS input  
becomes a line input just like the other mono line 
inputs.
To use guitars or other instruments on other  
channels, you will need to use an external DI box    
first. Without the DI box – or if this switch is not  
pressed in – guitars may sound dull and muddy.
7. Line Inputs  
Hi-Z Input (Channel 1 Only) [ProFX8v2 / ProFX12v2]
In addition to accepting balanced mic or line-level 
signals using an XLR connector, ProFXv2 Series mixers  
may also accept 1/4" line-level signals driven by  
balanced or unbalanced sources. These 1/4" jacks  
share circuitry (but not phantom power) with the  
mic preamps.
To connect balanced lines to these inputs, use  
a 1/4" Tip-Ring-Sleeve (TRS) plug. “TRS” stands for  
Tip-Ring-Sleeve, the three connection points available 
on a stereo 1/4" or balanced phone jack or plug.
