Owner's Manual 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. 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.
