While in setup mode, the display is used to show a series of menu choices that allow you to customize the Nº383 rather extensively, to better suit your system’s needs and personal preferences. The selector knob and the volume knob are used to select menu items and make adjustments, respectively. For more information on this customization, please see “Customizing Your Nº383.”

Pressing the mute button will reduce the main output level of the preamplifier by a user-modifiable amount, ranging from -10 to -73.2 decibels. Pressing the mute button a second time without adjusting the volume will return it to its previous setting.
