About Presets
The DPA amplifiers are preset driven. An understanding of how presets work is essential to get the most out of the amplifiers. A Preset, in the context
of the DPA amplifiers, is a combination of amplifier configuration (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 amplifiers come with 20 unchangeable factory presets, and 50 user-defined 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
configurations. Factory presets F10: thru F20: include basic settings along with the output configurations.
User-defined Presets
Presets U1 through U50 are all configured from the factory the same as factory preset F1. Anytime you save a preset, it overwrites one of the
User-defined Presets. There are three ways of creating user-defined presets.
• You can recall a user-defined preset with the output configuration you want, then modify the DSP parameters and SAVE it by overwriting the one
you recalled, or you can SAVE AS (overwrite) another user-defined preset.
• You can recall a factory preset, modify the parameters, then SAVE AS one of the user-defined presets. The SAVE procedure is not available for
factory presets.
• You can use the Preset Wizard to set the output configuration, power output, and other parameters, then SAVE AS (overwrite) a user-
defined preset.
