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.

2.Connect cords from the main outs to your powered speakers or amplifier.

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 amplifier level controls to however the manufacturer recommends. (This is usually all the way up.)

Set the Gain

1.Plug 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.

2.Engage the channel's PFL Solo switch to view the input level via the main meters.

3.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 fader and headphones level a little.

4.The mono channel gain affects the mic and the 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.

Note: there are two hybrid channels [9/10 and

11/12 on the ProFX16 and 15/16 and 17/18 on

the ProFX22] that have both mono mic and stereo line inputs. In these channels, the gain control affects only the mic gain.

5. Repeat steps 1 to 4 for the other channels.

Instant Mixing

1.To get sound out of the speakers and into a waiting world, engage a channel's L-R assign switch, turn up that 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!

3.Bring in other channels as mentioned above.

USB

The USB connection allows you to play two channels of audio from your computer, and to record the main mix to your computer. This feature is explained more thoroughly on pages 4, 9-10, 16 and 23.

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 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 your speakers.

Save the shipping box and receipt! You may need them someday.
