Loosely based on a dream sequence in which the technical writer is given keys to a 
sports car of his choice, unlimited gas, and closed roads. The dream suddenly ends and 
reality kicks in. A mixer manual to write, a mixer manual to write!
Set the levels
It’s not even necessary to hear what you’re doing to 
set optimal levels. But if you’d like to: Plug headphones 
into the phones output jack, then turn up the phones 
knob just a little.
1.  Turn on the mixer by pressing the top edge of 
the power switch.
2.  For one channel, press the solo switch in, and 
the rude solo light will turn on.
3.  Play something into that input at real-world 
levels.
4.  Adjust that channel's gain control until the 
right main meter stays around the 0 dB LED 
(marked "level set").
5.  Disengage the channel's solo switch.
6.  Repeat steps 2 to 5 for the remaining channels.
7.  Turn up the channel level to the "U" mark.
8.  Slowly turn up the main mix level until you 
hear the signals in your speakers.
9.   If needed, apply some channel EQ wisely.
10.  Adjust the channel levels to get the best mix. 
Keep the gain controls and levels fully down on 
unused channels.
11.  During the performance, if you notice a channel 
OL LED turning on during peaks, carefully turn 
down that channel's gain control until OL does 
not turn on.
FireWire
• 
See page 35 for details of getting started with 
FireWire.
• 
PC drivers are on the supplied CD-ROM. 
Mac OS X contains built-in drivers, so no  
software installation is required.
Other Notes
• 
When shutting down, turn off any power  
amplifi ers or powered speakers fi rst. When  
owering up, turn them on last. This will reduce 
the chance of turn-on or turn-off thumps.
• 
Always turn down the phones level when  
making connections, pressing solo, or doing 
anything that may cause loudness in the  
headphones. This will help protect your  
hearing.
• 
Always turn down the main mix level and  
control room level when making connections to 
the mixer. Better yet, turn off the power.
• 
Save the shipping box!
Quick Start
We realize that you must be really keen 
to try out your new mixer. Please read 
the safety instructions on page 2 and this 
page, and then have a look through some 
of the features and details in this manual.
Setup
Use the mixer in a nice clean and dry environment, 
free from dryer lint and dust bunnies.
Zero the controls
1.  Fully turn down all the knobs to minimum, 
except for the channel EQ and pan controls, 
which should be centered.
2.  Make sure all buttons are in the out position.
Connections 
1.  Make sure the AC power switch is off before 
making any connections.
2.  Push the linecord securely into the IEC  
connector on the rear panel, and plug it into a 
 3-prong AC outlet. The mixer can accept any  
AC voltage ranging from 100 VAC to 240 VAC.
3.  Plug a balanced microphone into one of the mic 
XLR (3-pin) connectors. Or connect any line-
level signal (keyboard, or guitar preamp) to a 
line input jack using a TS or a TRS 1/4" plug.
4.  If your microphone requires phantom power, 
press in the 48V phantom power button.
5.  You can connect a guitar directly to line inputs 
1 or 2 without needing a DI box, if you fi rst 
engage the hi-z switch on these channels.
6.  The insert jacks of channels 1 and 2 can be 
used to connect an external effects or dynamics 
processor into the signal chain.
7.  Connect the main outputs of the mixer (either 
XLR or TRS 1/4") to the line level inputs of your 
amplifi er (with speakers already attached) or 
to the line level inputs of powered speakers.
