s Manual

Getting Started

READ THIS PAGE!!

Even if you never read manuals, please 
read and digest the safety instructions 
on page 2, and this page before you 
begin using your mixer.

Zero the Controls

1.  Unplug the mixer’s external power supply from the 

mixer.

2.  Turn down all the gain, aux, and level controls, and 

center all the EQ controls.

3.  Set all push button switches to their “out” positions.

4.  In the center section, turn down the large level 

knob, FW in knob, and phones level knob.

Connections

If you already know how you want to connect the 

mixer, go ahead and connect the inputs and outputs 
the way you want them. If you just want to get sound 
through the mixer, follow these steps:

1.  Plug a signal source into the mixer. This could be a:

•  Turntable into the phono input.
•  Line-level source such as a CD player into a 

line-level input.

•  A guitar plugged into channel 1’s left input, 

with the instrument switch pressed in.

2.  Connect cords from the main outs to your powered 

speakers or amplifier.

3.  Plug in the mixer’s external power supply, and con-

nect it to a live AC outlet to turn on the mixer.

4.  If you have powered speakers, turn them on. Other-

wise, hook up your speakers to your amp and turn it 
on. Adjust your powered speaker or amplifier level 
controls to however the manufacturer recommends. 
(This is usually all the way up.)

Set the Levels

To set the gain controls, it’s not even necessary to 

hear what you’re doing at the outputs of the mixer. If 
you want to listen while you work, plug headphones into 
the phones jack on the front panel, then set the phones 
knob up a little.

1.  Play something into the selected input. Be sure 

that the volume of the input source is the same as 
it would be during normal use. If it isn’t, you might 
have to readjust these levels during the middle of a 
set.

2.  Adjust the channel’s rotary gain control so that the 

level set LED comes on while you are playing, and 
goes off when you stop. As a rough guide, adjust the 
gain until the LED is on for about half the time dur-
ing your performance. (The LED indicates that the 
signal level is 0 dBu.)

3.  Repeat for any other channels.

Instant Mixing

1.  To get sound out of the speakers, turn up the 

channel’s level control to the U (unity gain) position, 
and slowly rotate the large main control to a comfort-
able listening level.

2.  Sing and play. You’re a star! Bring in the other 

channels, and generally have fun.

3.  Grease the frying pan with hog fat and turn up the 

heat just enough to not fill the kitchen with fine 
blue smoke.

4.  Cook the sausages until golden brown, and serve 

with black pudding and a pint of warm beer.

FireWire

1.  See Appendix D, on page 21 for details of getting 

started with FireWire.

2.  There is a nice section about recording with 

FireWire on page 22.

3.  There is no step 3. Well, only this one, and it is not 

very informative. (Tech writers just love numbered 
lists.)

4.  There is no step 4 either.

Other Nuggets of Wisdom

•   Always turn down the main level control and phone 

level control before making any connections.

•   When you shut down your equipment, turn off the 

amplifiers first. When powering up, turn on the 
amplifiers last.
