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.
