Electrical characteristic data is used to enable load verification (LoadSmart) and monitoring facilities (SpeakerSafe)
to be performed on the 20000DP. This data set is termed a Fingerprint. When a 20000DP-specific loudspeaker type is
loaded, its Fingerprint load characteristics are included. These load characteristics are stored in a file with a “.mdl”
suffix and are loaded simultaneously with the module file.
LoadLibrary Modules and standard Module files are cross-compatible, although when a LoadLibrary Module is
loaded into a legacy Lake product the extra data within it is ignored.
11.7 Super Modules
Super Modules allow control of multiple Modules of the same type, distributed across multiple Frames, as a single
entity within the Lake Controller software. A change made in the Super Module is replicated across all assigned
Modules, resulting in improved efficiency in system configuration and a reduction of on-screen icons within the
Lake Controller software.
The key benefit of this feature is the ability to connect and control crossovers, levels and EQ across multiple
hardware devices simultaneously from the Lake Controller. For example, one device may be driving sub and low-
frequency speakers, while another device controls mid-range and hi-frequency drivers. Using a single adjustment
the crossover points between the two devices can be changed simultaneously.
Please refer to the Lake Controller Operation Manual for further information regarding Super Modules.
11.8 Loudspeaker Crossover Configuration Overview
The Lake Processing system may be configured with up to two inputs and up to six Module outputs, although the
number of power outputs will be either two or four depending on the PLM model being used. To make use of the
extra processing channels, multiple hardware devices may be connected together using the Super Module feature
as summarized in section 5.3.3.
Each set of processing elements is referred to as a Module and can be configured as crossovers, full bandwidth
auxiliary outputs, or a combination of the two. The relationship between inputs and outputs is defined via the Lake
Controller or via the front panel Input Config Menu.
The Lake Processing system provides two distinct categories of crossovers:
• Infinite Impulse Response filters (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 filters (FIR) providing zero phase shift with steep transition slopes at the crossover
frequencies. These are also referred to as Linear Phase Crossovers.
11.9 Files and Presets
The Lake system provides various methods for storing and recalling Module, Frame, or system-wide data. A
overview is provided below; for further information please refer to the Lake Controller Operation Manual.
11.9.1 Module, System and Sub-System Configuration Files
Module, System and Sub-System Configuration files are stored on the Lake Controller PC, and data is passed across
the network when recalling or storing these type of files.
