The following steps will help you set up the ProFX4v2 

mixer quickly.

1.  Turn down all knobs except the channel EQ.

2.  Set all channel EQ knobs and the graphic EQ 

sliders at their center detent.

3.  Set all buttons to the “out” position.

4.  Plug signal sources into the mixer, such as:

• 

Microphones plugged into the mic inputs. 
Engage phantom power if your mics need 
it. Check the mic's user manual to be sure.

• 

Line-level sources such as keyboards, drum 
machines, or CD players plugged into the 
line-level inputs.

5.  Connect cords from the main outs to your  

powered speakers or amplifier.

6.   Push the 2-pin female side of the power adaptor 

securely into the connector on the rear of the 
ProFX4v2. Plug the other end into an AC outlet 
properly configured with the correct voltage as 
indicated on the AC adaptor. Turn on the mixer.

7.  If you have powered speakers, turn them on. 

Otherwise, hook up your passive speakers to 
your amp with speaker cables, and turn it on. 
Adjust your powered speaker or amplifier level 
controls to the manufacturer's recommended 
settings.

8.  Be sure that the volume of the input is the 

same as it would be during normal use, or you 
may have to readjust the gain in the middle  
of a set. You can listen with headphones  
if you carefully turn up the channel level  
knob and headphones level a little.

9.   Adjust the gain knobs as desired.

10.  To get sound out of the speakers and into a  

waiting world, turn up that channel’s level knob 
to the “U” (unity gain) position, and slowly bring 
up the main mix knob to a comfortable listening 
level.

11.  Repeat steps 8 to 10 for the other channels.
