CONDITIONS: (1) THIS DEVICE MAY NOT CAUSE HARMFUL INTERFERENCE, AND

(2)THIS DEVICE MUST ACCEPT ANY INTERFERENCE RECEIVED, INCLUDING INTERFERENCE THAT MAY CAUSE UNDESIRED OPERATION.

Connections

1. POWER CONNECTION

This is a standard 3-prong IEC power connector. Connect the detachable linecord (included in the box with your mixer) to the power receptacle, and plug the other end of the linecord into an AC outlet. ProFX Series mixers have a universal power supply that accepts any AC voltage ranging from 100 VAC to 240 VAC. No need for voltage select switches. It will work virtually anywhere in the world. That’s why we call it a “Planet- Earth” power supply! It is less susceptible to voltage sags or spikes, compared to conventional power supplies, and provides greater electromagnetic isolation and better protection against AC line noise.

Disconnecting the plug’s ground pin is dangerous. Don’t do it.

2. POWER Switch

Press the top of this rocker switch inwards to turn on the mixer. The front panel power LED [36] will glow with happiness...or at least it will if you have the mixer plugged into a suitable live AC mains supply.

Press the bottom of this switch to put the mixer into standby mode. It will not function, but some circuits are still live. To remove AC power, either turn off the AC mains supply, or unplug the power cord from the mixer and the AC mains supply.

As a general guide, you should turn on your

mixer first, before any external power amplifiers or powered speakers, and turn it off

last. This will reduce the possibility of any turn-on, or turn-off thumps in your speakers.

3. USB INPUT/OUTPUT

The built-in USB interface allows for some powerful and flexible routing. It is a 2x2 interface allowing you to record two streams from the mixer, or to input stereo playback from a computer and route it to nearly any output or pair of outputs on the mixer.

The USB routing capabilities are as follows:

USB input TO the mixer - playback:

(1)Stereo channel 15/16 (on the ProFX16) and 21/22 (on the ProFX22) features a USB button, so one may route computer output (such as iTunes®) down the last stereo channel of the board. This stereo signal may then be EQ'd, sent to auxiliaries (i.e. to feed monitors, headphones or effects) and is routable to mains and/or subgroups via the fader routing features that are available on all other channels. In short, this signal may be sent to nearly any desired output or pair of outputs. Additionally, the gain knob at the top of this channel strip adjusts the USB input level to the mixer to achieve an optimal signal level.

(2)The 2-Track Return section features a flip switch, so a “Tape” source (such as an iPod® connected via RCA cables) or the USB signal from a computer

(playing Windows Media Player® files, for example) may be routed to the main bus. This section also features an input level adjustment for fading house music up and down between bands, at a house of worship, or any other event where this may be necessary.
