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.
