34. FW LOOP OUT
In addition to a mix of channels 1 to 4, the FireWire
output to the computer can contain the FireWire input
signal, if this switch is down. The mains and phones are
not affected by the switch, and always provide a full mix
of channels 1 to 4 and the 2-channel FireWire inputs.
• If disengaged (out), the FireWire output to
your computer will just be the main mix from
channels 1 to 4. This is a good position for
overdubbing, as any playback from your com-
puter can be played in your main speakers and
headphones, while you play along with a guitar
and record only the guitar via FireWire.
• If pressed in, the FireWire output to your
computer will be the mix of channels 1 to 4,
including any FireWire audio coming in from
your computer. This is a good position to record
live, where your complete main performance
(including any input from the computer) can
be recorded via FireWire.

35. PHONES LEVEL
This controls the volume of the headphones output
from off to maximum gain.
Warning: The headphone amplifier is de-
signed to drive any standard headphones to
a loud level. It can cause permanent hearing
damage. Even intermediate levels may be painfully loud
with some headphones. Be careful!
Always start with the phones level control turned all the
way down before connecting headphones or making any
connections. Keep it down until you’ve put on the head-
phones, and turn it down first whenever you press cue.
36. MAIN LEVEL
This conveniently-large knob adjusts the main mix
output level at the main outputs [6]. The meters will
also be affected by this control.
It does not adjust the levels to your headphones,
FireWire outputs, or the aux outputs.
