Phones, Mon, Tape and Main Mix
32. Phones
As one might expect, this knob controls the level
of the headphones. Make sure that this knob is fully
off [counter-clockwise] when adding a new source.
WARNING: The headphone amp is loud
and can cause permanent hearing damage.
Even intermediate levels may be painfully
loud with some headphones. BE CAREFUL!
Always turn the phones level control all the way
down before connecting headphones or doing anything
new that may affect the headphone volume. Then turn
it up slowly as you listen carefully.
33. Aux Mon Master
This knob provides overall control over the aux
mon levels just before they are delivered to the aux
mon send output.
Auxiliary is usually the control you turn up when
the lead singer glares at you, points at his stage monitor,
and sticks his thumb up in the air. (It would follow that
if the singer stuck his thumb down, you’d turn the knob
down, but that never happens.).
34. Tape Level
This knob controls the input level of signals entering
the tape inputs.

35. Main Mix
This knob allows you to adjust the levels of the
main mix signals sent to the main outputs.
This gives you the ultimate feeling of power and
control over the sound levels sent to your audience.
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.
The main mix signals are off with the knob fully
counter-clockwise, the “U” marking is unity gain,
and fully clockwise 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 knob 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).
This control does not affect the mon send, FX send or
tape outputs.
