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.
