Using the DN9848 Memories

8.STORING AND RECALLING SETTINGS

The DN9848 Loudspeaker Processor is provided with the following memory facilities:

32 lockable System memories, designated as S01 to S32, for storing standard set ups in battery-backed-up SRAM.

5 free access User memories, designated as U01 to U05, for storing a series of set ups for the current show.

99 Preset (flash) memory locations, designated P01 –P99, for secure storage of essential settings against overwriting or battery failure. These memories can only be programmed from an external computer. Up to 25 Factory Presets, including cross-over set ups for commonly used EV and third-party loudspeaker systems, are available at www.klarkteknik.com for downloading to the unit via the front panel PC port. These are listed with the Technical Specification in Section 11.
