Mackie ProFX4v2 Manual Do Proprietário

Owner’

s Manual

As one might expect, this knob controls the level  

of the headphones. Make sure that this knob is fully  
off [counter-clockwise] when adding a new source.

WARNING: The headphone amp is loud  
and can cause permanent hearing damage. 
Even intermediate levels may be painfully 

loud with some headphones. BE CAREFUL! 
 Always turn the phones level control all the way  
down before connecting headphones or doing anything 
new that may affect the headphone volume. Then turn  
it up slowly as you listen carefully.

This knob provides overall control over the aux  

mon levels just before they are delivered to the aux  
mon send output.

Auxiliary is usually the control you turn up when  

the lead singer glares at you, points at his stage monitor, 
and sticks his thumb up in the air. (It would follow that 
if the singer stuck his thumb down, you’d turn the knob 
down, but that never happens.).

This knob controls the input level of signals entering 

the tape inputs.

This knob allows you to adjust the levels of  the  

main mix signals sent to the main outputs.

This gives you the ultimate feeling of power and  

control over the sound levels sent to your audience.

 

Adjust this control carefully, with your good eye on  
the meters to check against overloading, and your  
good ear to the levels to make sure your audience  
(if any) is happy.

The main mix signals are off with the knob fully  

counter-clockwise, the “U” marking is unity gain,  
and fully clockwise provides 10 dB of additional gain. 
This additional gain will typically never be needed,  
but once again, it’s nice to know that it’s there.  
The knob is stereo, as it affects both the left and  
right of the main mix equally. This is the ideal control  
to slowly bring down at the end of a song (or quickly  
in the middle of a song if the need ever arises).

This control does not affect the mon send, FX send or 

tape outputs.
