Appendix C: USB 3/4 Return Setup

Introduction

ProFXv3+ mixers allow you to send audio from the computer into either the USB 1/2 Blend Mix or the 3/4 Main Mix.
USB 1/2 is most useful for overdubbing when recording, while 3/4 is typically used for backing tracks, streaming or game audio.
When connected to a computer, the ProFXv3+ defaults to USB 1/2. To change this to USB 3/4, the computer's settings will need
to be changed. Here we cover basic Windows and Mac setup applications that use the system's audio settings.
Some DAWs and other streaming applications have their own settings that may override system settings.
If so, please review their documentation on how to make changes to the DAW / app.

Windows

1. Download the USB driver from the Mackie website.
2. Follow the installation instructions to install the driver.
3. Right-click on the speaker icon located on the task bar.
4. Select Sound Settings.
5. Under "Choose Your Output Device", select ProFXv3+ 3-4 from the dropdown menu.
6. On the mixer, be sure the USB 3/4 button is engaged (down) on the second-to-last channel.
7. On the ProFX12v3+ mixer, engage the LR routing button located next to the fader. This will send the signal to the main mix.
8. Turn up the channel fader to unity, then slowly turn up the main mix fader.
You will know this worked if the main meters illuminate and you hear PC audio through the device connected to the main outputs.

Mac

A driver download is not necessary on a Mac. However, some parameters will still need to be changed within macOS.
1. Open the Audio MIDI Setup app using the Spotlight search (Command + Spacebar).
2. Right-click on the device and select the ProFXv3+ mixer in "Use This Device For Sound Input",
as well as "Use This Device For Sound Output".
3. Select the 'Configure Speakers' button and be sure it is set to 'Stereo'.
4. Change the Left and Right options to Analog 3 and 4, then tap 'Apply'.
5. On the mixer, be sure the USB 3/4 button is engaged (down) on the second-to-last channel.
6. On the ProFX12v3+ mixer, engage the LR routing button located next to the fader. This will send the signal to the main mix.
7. Turn up the channel fader to unity, then slowly turn up the main mix fader.
You will know this worked if the main meters illuminate and you hear PC audio through the device connected to the main outputs.
