Output Volumes and Output Volume Links
Within the Output Section you can find individual volumes for different physical outputs.
With the "Output Linked” soft buttons, you can link, or unlink, the respective volume to the MASTER VOLUME knob.
Any linked volumes will be controlled by the MASTER VOLUME knob, without having to enter the Output Section
again. You can link more than one volume to Master Volume. An obvious live application is to unlink the Main Output
connected to the main mixing desk of the venue – this means you can now change the volume of your monitor
signal, or headphones, while the all-important main signal remains unchanged.
Did not see that... Thx a lot
