This diagram shows an electric/acoustic guitar connected to input 1’s 1/4” input, a vocal microphone
connected to channel 2’s XLR input, a keyboard connected to input 3, and an electronic drum kit con-
nected to channel 4’s line input.
The main outputs are fed to a pair of Mackie SRM450s and subwoofers for the audience’s listening
pleasure. The mixer’s Big Knob controls their volume. Use the left aux send to connect to 4 SRM350s for
stage monitoring. (The mixer automatically sums the stereo signal to mono if you use the left channel
output only.)
A laptop is connected via FireWire. The mixer provides stereo mains to the computer for recording with
most DAW applications like Tracktion, Cubase or Sonar™. Perfect for recording your set. Any playback
software applications like iTunes™, or Tracktor™ can be used for break music by utilizing the FireWire
stereo return with its own mix level control into the mains.
