Stage monitors allow the talented musicians in the 

band to hear themselves clearly on stage. This can be a 
good thing! The monitor mix may be carefully adjusted 
in level using the aux mon controls. These tap a portion 
of each channel's signal to provide a 1/4" TRS output 
here to feed external stage monitors. These could  
either be passive stage monitors powered by an  
external amplifier, or powered stage monitors with  
their own built-in amplifier.

The monitor signal is the sum (mix) of all the  

channels whose aux mon control is set to more  
than minimum. If they want “more me and less Brian,” 
you may turn up their channel's aux mon control,  
and turn down Brian's.

The overall output level may be adjusted with the  

aux master mon knob and mon 1 may have its EQ 
tweaked with the graphic EQ if the main mix/mon 1 
switch is engaged. Alternatively, you could add an  
external graphic EQ between this output and your  
powered monitors. This will allow you to adjust  
the EQ, and minimize the chance of feedback from 
nearby microphones.

The monitor output is not affected by the main  

mix fader or the channel faders. This allows you to set 
up the monitor mix and level just right, and not have  
it change when a channel fader or the main mix fader  
is adjusted. This is known as “pre-fader.”

There is one mon send jack on each ProFX8v2 
and ProFX12v2, two mon send jacks on each 
ProFX16v2 and ProFX22v2 and three mon 
send jacks on each ProFX30v2.

This 1/4" TRS line-level output may be used to feed  

an external effects processor (FX), such as a nice  
sound effect, or delay unit. The output from this jack  
is an exact copy of what goes into the internal FX  
processor, being the careful mix of all channels whose 
aux FX control is turned to more than minimum.

(The processed output of the internal FX does not 

come out of this output, but is added internally to the 
main mix or monitor mix.)

The overall output level may be adjusted with the 

aux master FX knob. (This knob also affects the level  
going into the internal FX.)

The output is “post-fader,” so any changes to the  

channel faders will also affect the level going to the 
external processor.

The processed output from the effects processor  

is usually returned to the aux/stereo returns or a  
spare channel, and you may carefully mix the original 
unprocessed channel (dry) and the processed channel 
(wet). Altering the original channel fader increases 
both the wet and dry signals and keeps them at the 
same delicate ratio. For example, the reverb remains  
at the same level relative to the original.

This 1/4" TRS connector is where to connect your 

favorite footswitch. This allows you to easily mute or 
un-mute the internal effects at will. Any one-button  
on/off footswitch will work.

If the internal FX have already been muted with the 

internal FX mute switch, then the footswitch has no 
effect.

The ProFX30v2 has an additional mon send 
jack in place of an FX footswitch jack.

The stereo (aux) returns are designed for 1/4" TRS 

balanced or 1/4" TS unbalanced signals, from -20 dB to 
+20 dB. They allow the stereo processed output from 
external effects processors or other devices to be added 
to the main mix.

Level adjustment of the incoming signals is made with 

the aux return controls.

You may also use these inputs to add any stereo  

line-level signals to your main mix, so it could be  
another line-level source, not just an effects processor.

If you are connecting a mono source, use the left 

(mono) stereo return input, and the mono signals will 
appear on both sides of the main mix.
