Getting Started

Read and understand the Important Safety Instructions on page 2.
Turn down all knobs except the channel EQ and pan knobs, and set all the faders fully down.
Set all channel EQ knobs and pan knobs at their center detent.
Disengage all switches.
Connect cords from the main outs to powered speakers (or to an amplifier connected to passive speakers).
Push the line cord securely into the mixer's connector and plug the other end into a grounded AC outlet. The mixer may accept the appropriate voltage as indicated near the connector.
Turn the mixer on.
Turn the powered speakers (or amplifiers) on.
Plug signal sources into the mixer, such as:
- Microphones plugged into the mic inputs. (Engage phantom power if needed.)
- Line-level sources such as keyboards, drum machines, or CD players plugged into the line-level inputs.
- Smartphone paired and connected via Bluetooth.
Be sure that the volume of the input is the same as it would be during normal use.
Engage the channel's L-R assign switch (PROFX12v3+) and turn up that channel's fader to the “U” (unity gain) position.
Slowly bring up the main fader to a comfortable listening level.
Repeat steps 9 to 11 for the other channels.
