6.3.2 LoadLibrary
™
In addition to the standard loudspeaker presets (Module files), the Lake Controller also includes a set of
enhanced Module files specifically for use with the PLM Series.
These supplementary PLM Module files, known as the LoadLibrary incorporate both Lake DSP parameters
along with PLM specific data; LoadLibrary Module files include parameter settings for the PLM's Amplifier
Gain and ISVPL limiter. Additionally, LoadLibrary loudspeaker types may also include data relating to the
electrical characteristics of a particular loudspeaker.
Electrical characteristic data is used to enable load verification (LoadSmart) and monitoring facilities
(SpeakerSafe) to be performed on the PLM. This data set is termed a Fingerprint. When a PLM-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.

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.

Loudspeaker Crossover Configuration Overview

The Lake Processing system within PLM Series devices 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 6.3.3.
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.
