Apogee Duet Output Parameters
The output parameters determine the output and muting behavior of the Duet.

Level pop-up menu: Determines the output. You can choose between Line −10 dBV and Instrument Amplifier.
Mute checkbox: Mutes the output chosen in the Mute Behavior pop-up menu.
Mute Behavior pop-up menu: Determines which output is muted when the Mute checkbox is selected. Choose the Toggle Main Output/Headphones setting to alternate between muting the main output and the headphone output—by selecting the Mute checkbox.
