Loosely based on a dream involving strong personalities and even stronger 
drinks...wait, that wasn't a dream?

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 fader to the "U" mark.
8.  Slowly turn up the main mix fader until you 

hear the signals in your headphones.

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.

•  When shutting down, turn off any power

amplifiers or powered speakers first. When  
powering 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

monitor level when making connections to the 
mixer. Better yet, turn off the power.

•  Save the shipping box!

We realize that you must be really keen 
to try out your new mixer. Please read the 
safety instructions on page 2, then have 
a look through some of the features and 

details in this manual.

Use the mixer in a nice clean and dry environment, 

free from dryer lint and dust bunnies.

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.

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, 

turn on the 48V phantom power button.

5.  All mono channels have insert jacks that can be 

used to connect an external effects or dynamics 
processor into the signal chain.

6.  Connect the main outputs of the mixer (either 

XLR or TRS 1/4") to the line level inputs of your 
amplifier (with speakers already attached) or 
to the line level inputs of powered speakers.
