ProFX8 and ProFX12
Introduction
ThankyouforchoosingaMackieprofessionalProFX
mixer. It is equipped with our rather lovely microphone
preamps, an internal FX processor and a USB port for
playing and recording 2 channels of audio using a
computer. The ProFX8 has 8 channels and the ProFX12
has 12 channels. Apart from this difference, the mixers
are identical and this manual covers both models.
AtMackie,weknowwhatittakestoberoadworthy.
After all, our mixers have traveled all over the world,
often under the worst of conditions, and we’ve applied
what we’ve learned to the mechanical design of our
ProFX mixers.
Reliability is paramount to sound reinforcement.
That’s why our engineers have subjected our mixers
to the most rigorous and fiendish tests imaginable to
fine-tune the design, and extend its limits beyond
those of ordinary mixers.

How To Use This Manual
The first few pages after the table of contents are the
hookup diagrams. These show typical setups for fun
times with your ProFX8 or ProFX12 mixer.
Next is a detailed tour of the entire mixer. The
descriptions are divided into sections, just as the
mixer is organized into distinct zones:
• RearPanel:TheACinput,powerswitch, 
XLR line-level outputs and USB I/O
• ConnectionSection:Theuppersection,where
you connect microphones, guitars, etc.
• ChannelControls:Thechannelstripswhere
you adjust and control each channel
• MasterControls:Thesectionontheright,with
graphic EQ and main level controls
• StereoEffectProcessor
Throughout these sections are illustrations with
each feature numbered and described in the nearby
paragraphs.
This icon marks infor mation that is critically
important or unique to the mixer. For your own
good, read them and remember them.
This icon will lead to some explanations of
features and practical tips. Go ahead and skip
these if you really need to go.
