• The settings at the time you powered-off are remembered. When you turn on the power again, the unit will start up with NOTE the same settings. You can use the “Last Mem.

Rear Panel y Ground screw The AC power cord is a 3-wire type. If the AC outlet used is earthed (grounded), this device will be properly earthed as well. Also, grounding the screw sometimes reduces hum and interference noise. u [AC IN] connector Connect to the AC mains using the supplied AC power cable.
Panel operations By pressing buttons on the panel you can monitor or control various parameters of the ACD1 itself or of the con- nected ampliﬁers. The following parameters can be monitored/controlled. Category Sub category Operation performed 1. Scene Recall Recalls a scene on the speciﬁed ampliﬁer.
NO] button. Basic operation As an example, we’ll explain how to store the scene of an ampliﬁer connected to the ACD1. The basic operation is the same for all parameters. From the HOME screen, press the [NEXT] button and then use the [▲INC/YES] / [▼DEC/NO] buttons to select the [Scene] cat-...
• If the display indicates “Parameter Locked!”, Panel Operation is set to “View Only.” To temporarily defeat the panel lock, NOTE hold down both the [▲INC/YES] / [▼DEC/NO] buttons for at least three seconds. To disable the panel lock, ﬁrst defeat it temporarily, and then turn the Panel Operation setting Normal (page 14).
• Scene names that can be displayed by the ACD1 are a maximum of 12 characters. If a scene name of 13 characters or longer is speciﬁed in Amp Editor, the ACD1 will not display the thirteenth and subsequent character.
Standby/On Selects the status of the power supply. • If you select “ALL” as the [Amp ID], the power supply status may indicate “Some Standby.” This means that the power is NOTE On for some ampliﬁers, and Standby for others.
