Power Connector [Profx12V3+]; Power Switch; Usb-C Computer Jack - Mackie ProFXv3+ Series Owner's Manual

PROFXV3+ MULTI-CHANNEL ANALOG MIXERS WITH ENHANCED FX, USB RECORDING MODES, AND BLUETOOTH®

Power Connector [ProFX12v3+]

This is a standard 3-prong IEC power connector. Connect the detachable power cord (included in the packaging
with the ProFX12v3+) to the power receptacle, and plug the other end of the power cord into an AC outlet.
Make sure that the AC power is matched to the AC power indicated on the rear panel (near the IEC receptacle).
Warning: Disconnecting the plug's ground pin is dangerous. Don't do it!

Power Switch

Located next to the power connector is the power switch. Press the top of this rocker switch in to turn the ProFXv3+ mixer
on and press the bottom of this switch in to turn it off.
As a general guide, the ProFXv3+ should be turned on first, followed by external power amplifiers or powered
speakers. As such, the ProFXv3+ should also be turned off last. This will reduce the possibility of any turn-on
or turn-off thumps in the PA.

USB-C Computer Jack

This is a 2x4 interface that allows audio to stream to and from the ProFXv3+ mixer via computer.
Connect the USB-C side of a USB cable to the ProFXv3+ mixer and the USB-A side to the computer's USB port.
Don't forget to change the input and output to 'ProFXv3+' via Settings on your computer.
ProFXv3+'s USB connection is audio only. It is not a source of power.
