Owner’s Manual
• Pressing the headphone button while headphone 2 is active will switch control
back to headphone 1.
The last selected headphone control (1 or 2) is what will be active when the
headphone button is pressed. For example, let’s say the Main button is pressed
while headphone 2 is active. If the headphone button is pressed again, control will
return to headphone 2 (the last selected control).
Note: When in Headphone Control mode, the knob will NOT time out and return to
Monitor Control.
Output Meters - These meters display the signal level before the main output level
control.
Mute / Dim Button - By default, pressing the Mute button will mute the Main
outputs. Optionally, when using Universal Control, the mute button can be
configured in Universal Control to function as a dim button. The amount of dim
applied is -10 dB by default but can also be changed in the Settings Panel of the
Universal Control mixer.
Note: Mute / Dim does not affect headphones.
