2.   For mono channels, adjust the gain control so 

the level set LED just comes on occasionally 
during the loudest parts of your performance. 
The mono channel gain affects the mic and the 
line inputs. The hybrid channel gain affects the 
mic input only, not the stereo line inputs.

 

The stereo channel gain adjusts the stereo line 
inputs. Adjust as desired, and check the OL 
LED does not come on during the loudest pas-
sages.

3.   Repeat steps 1 to 2 for your other channels.

Instant Mixing 

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

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

2.  Sing and play. You’re a star! Bring in the other 

channels, and adjust their faders to make a 
nice mix and generally have fun. 

USB

The USB connection allows you to play 2 channels of 

audio from your computer, and to record the main mix 
to your computer. See Appendix D on page 32 for details 
of getting started with the USB.

Notes

For optimum sonic performance, the channel faders 

and main fader should be set near the “U” (unity gain) 
markings.

Turn down all faders before making connections to 

and from your ProFX mixer.

When you shut down your system, turn off your ampli-

fi ers or powered speakers fi rst. When powering up, turn 
them on last. This will prevent the possibility of turn-on 
and turn-off thumps heard in your speakers.

Save the shipping box! You may need it someday. 

Read This Page!

You probably want to try out your new  
mixer right away. Before you do, please 
read the safety instructions on page 2, 
then read this page, and the rest later. 

Zero the Mixer

1.  Turn down all knobs except the channel EQ and 

pan knobs, and set all the faders fully down.

2.  Set all channel EQ knobs, pan knobs, and the 

graphic EQ sliders at their center detent.

3.  Set all buttons to the "out" position.

4.  Whistle a popular show tune.

Connections

If you already know how you want to connect the 

mixer, go ahead and connect the inputs and outputs 
the way you want them. If you just want to get sound 
through the mixer, follow these steps:

1.  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.

• 

A guitar plugged into channel 1, with the 
line/hi-z switch pressed in.

2.  Connect cords from the main outs to your pow-

ered speakers or amplifi er.

3.  Plug in the mixer’s power cord to a live AC 

outlet and turn on the mixer.

4.  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 amplifi er level 
controls to however the manufacturer recom-
mends. (This is usually all the way up.)

Set the Gain

1.   Play something into an input. This could be an 

instrument, you singing or speaking, or a line 
level source such as a keyboard or CD player. 
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 care-
fully turn up the channel fader and headphones 
level a little.

Please write your serial number here for future 
reference (i.e., insurance claims, tech support, 
return authorization, make dad proud, etc.)
