Mackie 402

Using a Mackie 402 (or similar 4 channel audio mixer) on a typical PESI gig

HOW TO USE A MACKIE 402 ON A SIMPLE PROGRAM

EVENT ROOM AUDIO SITUATION/BREAKDOWN

1x Wireless Lavalier
1x Wireless Handheld
1x Laptop Audio
Audio needs to route to Camera XLRs
Audio needs to route to Room Wall Patch or PA's

If you want to label up your Mackie - a label maker or console tape and a sharpie

Wireless Lavalier receiver going into MIC 1 (Channel Strip 1) - via XLR

MIC VS LINE LEVEL

MIXER SETTINGS MIC LEVEL (DEFAULT)

I typically default to Mic Level on camera XLR's as it offers a 20db gain on the audio signal.

Camera XLR's set to Mic level - typically recommend set for 40-50% on XLR dials
MAIN MIX set at Unity (U)
Channel Strip 1 & 2 | GAIN (top) set to Unity (u)
Channel Strip 1 & 2 | EQ (HI/Low) set Unity (u)
Turn down PHONES (Room Audio)
Channel Strip 1, 2 & 3 pots | LEVEL adjust levels as needed for audio levels in camera to be peaking on loud part at -6db (Self-test wearing lavalier on sternum, holding handheld w/ camera headphones on ears)
Turn up PHONES so that Room Audio is at a comfortable level without feedback (or edge of feedback)

MUTING UNUSED CHANNELS
Turn down LEVEL (channel pot) for appropriate channel/microphone in order to mute. Mixers this small unfortunately do not have a mute buttons.

MIXER SETTINGS LINE LEVEL

There is a 20db drop in volume in going from Mic Level to Line Level. I typically use Line Level only when there is some audio issue I simply can't figure out

Camera XLR's set to Mic level - typically recommend set for 90-100% on XLR dials
MAIN MIX at Maximum
Channel Strip 1 & 2 | GAIN (top) set to maximum
Channel Strip 1 & 2 | EQ (HI/Low) set Unity (U)
Turn down PHONES (Room Audio)
Channel Strip 1, 2 & 3 pots | LEVEL adjust levels as needed for audio levels in camera to be peaking on loud part at -6db (Self-test wearing lav on sternum, holding handheld w/ camera headphones on ears)
Turn up PHONES so that Room Audio is at a comfortable level without feedback (or edge of feedback)

MUTING UNUSED CHANNELS
Turn down LEVEL (channel pot) for appropriate channel/microphone in order to mute. Mixers this small unfortunately do not have a mute buttons.

SPEAKER ON MAC OS WITH VIDEO CLIPS SITUATION W/ A MACKIE 402

On the speaker's MAC OS Laptop, click on the arrow next to Unmute and select Leave Computer Audio

When this is done correctly, you should see Join Audio where Unmute was.

This improves audio in case of messing up turning down MAC OS direct box audio on the mixer fast enough so that it's not horrendous at first.

Leave Computer Audio

Done Correctly: You should see Join Audio

Main Out/Mix goes to your camera - typically set to Unity (u)
Phones goes to room audio
Turn down Main Out/Mix to your camera once any video clips plays. Turn Main Out/Mix back up to Unity (u) immediately upon video clip ending or pausing (your hands should be on the ready on the mixer!)
- This means that when video or audio clips play, the audio will only play in the room and not in your camera/headphones.
- The audio will play for remote webinar attendees as the speaker will be sharing their computer audio as ticked in the Zoom Share Screen dialog
