Preset izard
The Preset Wizard simplifies the preset creation process, and allows you to create a preset from the ground up. The Preset Wizard provides a
mechanism for you to select the desired power and load. Based on these selections, the best amplifier configuration is selected and you are then
allowed to select and assign loudspeakers to each output.
NOTE!: The power levels shown in this procedure are taken from the DPA4.3 unless indicated otherwise. DPA4.2 will show less power
and DPA4.5 will show greater power. For complete details refer to the
