This diagram shows an acoustic guitar microphone attached to channel 1’s XLR input, a vocal condens-
er microphone connected to channel 2’s XLR input, a guitar and amp modeler (like a Line 6 Pod™) con-
nected to channel 3, and a synthesizer workstation connected to channel 4. A northbound train loaded
with pig-iron is leaving Little Rock at 3:30.
The main outputs are fed to a pair of Mackie HR studio monitors for control room listening, and the
mixer’s Big Knob controls their volume. The headphone output has its own level control, and each chan-
nel has a cue switch independent of the Big Knob.
A laptop is connected via FireWire. The mixer provides stereo mains to the computer for recording with
most DAW applications like Tracktion, Cubase™ or Logic™. This is independent of the Big Knob as well.
The laptop is loaded with awesome virtual instruments like those in applications such as Logic, and a
USB key/pads combo controller is connected for real-time performance and recording.
The FireWire loop through switch on the top of the mixer makes overdubbing a breeze. In it’s normal
“out” position, you can playback the mix from your DAW and it will not loop back through the FireWire.
Only the analog inputs 1-4 will be available for recording. Track it!
