2. For mono channels, adjust the gain control so
the level set LED just comes on occasionally
during the loudest parts of the 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 make sure
that the OL LED does not come on during the
loudest passages.
3. Repeat steps 1 and 2 for the 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 the computer, and to record the main mix to
the computer.
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 the ProFX mixer.
When shutting down the system, turn off amplifiers or
powered speakers first. When powering up, turn them
on last. This will prevent the possibility of turn-on and
turn-off thumps heard in 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 the 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 powered
speakers or an amplifier.
3. Plug in the mixer’s power cord to a live AC
outlet and turn on the mixer.
4. If using powered speakers, turn them on.
Otherwise, connect passive speakers to an amp
with speaker cables, and turn it on. Adjust the
powered speaker or amplifier level controls
to however the manufacturer recommends.
(This is usually all the way up.)
Set the Gain
1. Play something into an input. This could be an
instrument, 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 the gain may
have to be readjusted in the middle of a set. You
can listen with headphones by carefully turning
up the channel fader and headphones level a
little.
