73. MAIN MIX
This stereo fader allows you to adjust the levels of the
main mix signals sent to the XLR and 1/4" main
line-level outputs [8, 10], and the tape outputs [15].
This gives you the ultimate feeling of power and
control over the sound levels sent to your audience. If
you press the main mix switch [44], you can see the
main mix levels in the meters [49]. Adjust this control
carefully, with your good eye on the meters to check
against overloading, and your good ear to the levels to
make sure your audience (if any) is happy.
This control does not affect the aux outputs [19] or
the main mix FireWire outputs. It affects the control
room or headphones if the main mix switch [44] is
engaged.
The main mix signals are off with the knob fully down,
the “U” marking is unity gain, and fully up provides 10
dB of additional gain. This additional gain will typically
never be needed, but once again, it’s nice to know that
it’s there. The fader is stereo, as it affects both the left
and right of the main mix equally. This is the ideal
control to slowly bring down at the end of a song (or
quickly in the middle of a song if the need ever arises).
74. ASSIGN TO FW 15-16
This switch allows you to assign the left and right
main mix to FireWire outputs 15 and 16. For example,
you can record the live performance main mix onto your
computer. This does not affect the analog main mix
outputs.
The output level to your computer is not affected by
the main mix fader [73].
Congratulations! You’ve just read about all the
features of your mixer. Time for a frosty beverage.
