About Presets

The DPA amplifi ers are preset driven. In order to get the most out of the amplifi ers, an understanding of how presets work is essential. A Preset, in the
context of the DPA amplifi ers, is a combination of amplifi er confi guration (inputs and outputs), DSP and loudspeaker assignments. When a preset is
recalled it can change the output routing and any of the DSP settings.
The DPA amplifi ers come with 20 unchangeable factory presets, and 50 user-defi ned presets. The factory presets are designed to be starting points
for creating the presets you need for your particular installation. Factory presets F1: thru F9: have no DSP or loudspeaker assignments, only output
confi gurations. Factory presets F10: thru F20: include basic settings along with the output confi gurations.
Creating User-defi ned Presets
A preset can be created in two ways, the fi rst is to modify an existing preset, then save this as a new preset. The second is to use the Preset Wizard to
create a Preset from scratch.
Save As a New Preset
After selecting a starting preset, navigate through the Input and Output menus to select and modify the parameters needed for your system. After
modifying the parameters for each channel, return to the Preset menu and save your work. If you started with a user-defi ned preset, you can update
the preset you started with using the SAVE function or, you can use the SAVE AS function.
Preset Wizard
The Preset Wizard simplifi es 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 amplifi er confi guration is selected and you are then
allowed to select and assign loudspeakers to each output.
NOTE: By default, all 50 of the user-defi ned presets are confi gured the same as factory preset F1. Either method described above
"overwrites" some existing preset. The main difference is the SAVE function overwrites only the preset number you started with, and the
SAVE AS function allows you to save to a different user preset number and change the name.
