Getting Started

We realize that you must be really keen to try out 

the mixer. Please read the safety instructions on page 
2, 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 and faders 

 

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.

WARNING:

 Before plugging the AC power 

cord into the mixer, make sure the VOLTAGE 
SELECTOR switch is set to the same voltage 
as the local AC mains supply (see page 13).

2.  Push the linecord securely into the IEC  

connector on the rear panel, and plug it into a 
 3-prong AC outlet. The mixer may 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.  Channels 1-8 have insert jacks that can be used 

to connect an external effects or dynamics 

processor into the signal chain.

6.  Connect the XLR or TRS 1/4" main outputs 

 

of the mixer  to the line level inputs of your 
amplifier (with speakers already attached) 

 

or to the line level inputs of powered speakers.

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 

 

CR/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.
3.  Engage the mode switch in the master 

 

section. A green level set light will turn on.

4.  Play something into that input at real-world 

levels.

5.  Adjust that channel's gain control until the 

left main meter stays around the 0 dB LED 
(marked “level set”) and never goes higher 
than “+7.”

6.  Disengage the channel's solo switch.

7.  Repeat steps 2 to 6 for the remaining channels.
8.  Turn up the channel fader to the “U” mark.
9.  Slowly turn up the main mix fader until you 

hear the signals in the headphones.

10.  If needed, apply some channel EQ wisely.
11.  Adjust the channel faders to get the best mix. 

Keep the gain controls and levels fully down 

 

on unused channels.

12.  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.

Things to Remember

•  Never listen to loud music for prolonged 

 

periods. Please see the Safety Instructions on 
page 2 for information on hearing protection.

•  Always turn down the main mix fader and 

control room/phones knob down when making 
connections to the mixer. Better yet, turn off 

the power.

•  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.

•  Save the shipping box!
