Output View

The output view let's you adjust gain, delay, mute and phase inversion for the corresponding output if the system preset allows modification of these values.

Furthermore, output EQs, X-Over filters and limiters can be adjusted if the preset grants access to these parameters.

 

 

The EQ Editor is explained in its own chapter. See EQ Editor
