12.4. Loudspeaker Processor Overview
The Lake Processing system within D Series Lake devices may be congured with up to four processing Modules
containing a total of up to twelve processing Module outputs that can be routed to any of the four power output
channels. Each set of processing elements is referred to as a Module and can be congured as crossovers, full
bandwidth auxiliary outputs, or a combination of the two. The relationship between inputs and outputs is dened
via the Lake Controller.
The Lake Processing system provides two distinct categories of crossovers:
• Innite Impulse Response lters (IIR) such as the classic Bessel, Butterworth or Linkwitz–Riley types; these are
available with slopes ranging from 6 dB/octave to 48 dB/octave.
• Finite Impulse Response lters (FIR) providing zero phase shift with steep transition slopes at the crossover
frequencies. These are also referred to as Linear Phase Crossovers.

12.6. Frame and System Presets
The entire processor conguration can be stored as a Frame Preset on this hardware device. Presets can be
recalled) via the Lake Controller software or Preset Manager utility; presets can be stored using the Lake Controller
software or Preset Manager utility. A maximum of 100 Frame Presets can be stored on this device. The data within
a Frame Preset encompasses the congurations of all Modules in the Frame, including levels, crossover, EQ, input
mixer, routing, and all other parameters. As Frame Presets are stored in the hardware device, recall is available
without using a PC.
