The Mix 2 Outs carry the sum of all the Mix 2 inputs.  This is the output to connect to your power 
amp, or to your amp's effect return jacks.  If you need an output with the Cabinet Simulator, then 
use the Direct or the Balanced Outs instead. 
 
 

3.3  Setting Levels 

 
[

Note:

  This section assumes you have already connected your system together properly.  You 

may want to come back to this section later if you are not ready to set levels now.] 
 
The System Mix Plus inputs are set to unity gain.  The relative levels of all of your inputs are 
therefore determined by the output levels of your devices.  Setting levels is a critical part of your 
guitar system.  Proper levels allow you to minimize noise, maximize your tone, and control the 
overall effect balance. 
 

1.  Setting up  

  Set both Mix Level knobs at unity gain (12 o'clock).   

  Turn the input and output levels of your effects all the way OFF.   

  Set each effects device to 100% effects, by turning the wet/dry mix to wet or the "direct" 

signal off. 

  If you are using the System Mix Plus volume control, set the volume to its maximum. 

 

2. Amp signal 

Play the guitar and adjust the preamp output level or the amp's effect send level until the yellow 
level LED just barely lights during signal peaks.  

The red LEDs indicate clipping.  Lower the 

level if you see them light up. 

 

3. Effects Inputs 

One by one, raise the input level of each of your effects devices to the maximum level 
recommended by the manufacturer.   
 

4. Effects Outputs 

One by one, raise the output level of each of your effects devices, always checking the System 
Mix Plus LEDs.  Set the levels as high as you can without overloading.   
 

5. Wet/Dry Balance 

You may reduce the output level of the effects devices if you want less effects in your final mix.  
If you want more effects, lower the output of your preamp or effect send, and repeat steps 3 and 
4. 

 
6. Final Output Level 

The Mix 2 knob typically acts as the master volume control for the entire system.  This knob can 
control your stage volume, or direct signal volume.  The Mix 2 level control does provide up to 6 
dB of gain, so be careful to avoid overloading the inputs to your power amp.  Unity gain (straight 
up) or less is typical.
