8. DC Input
This DC input connector is used to supply power to
the mixer. Connect the supplied external power supply
here, and plug the other end of the power supply into
the AC mains. The power LED [28] will joyfully illumi-
nate, indicating that the mixer is powered on, and ready
for action.
The universal external power supply that comes with
your mixer can accept any AC voltage from 100 VAC to
240 VAC.
9. FireWire Connection
FireWire (IEEE 1394) is a high-speed serial I/O inter-
face for connecting digital devices. The mixer has one
FireWire connector for transferring digital audio to and
from your computer.
The FireWire interface provides two audio outputs to
your computer:
• Main mix output, left and right. These output
signals are independent of any adjustments
made to the main level control [36]. This al-
lows you to easily record your live performance
directly to your laptop.
• The FireWire loop out switch [34] lets you
choose if you want the FireWire input to be
connected to the FireWire output for recording.
See page 19 for more details of this switch.
The FireWire interface also lets you use your com-
puter to playback two channels into the mixer:
• Left and right signals from your computer are
added to the main mix. The FW in control [33]
allows you to adjust the level of the incoming
audio being added to the main mix.
See Appendix D on page 25 for more FireWire details,
and the block diagram on page 24.
