28Signal Flow and Lake® ProcessingPLM Series Operation M anual R ev 1.3.56.4 Modules and Frames6.4.1 OverviewA Frame represents one physical Lake Processor (e.g. PLM 10000Q). A maximum of two Modules arecontained within each Frame; these are referred to as Module A and Module B. The number of Modulesshown in a given Frame is dependent upon the signal processing configuration of that Frame.Each Module can be configured as a Classic Crossover (Bessel, Butterworth, Linkwitz-Riley), as a LinearPhase Crossover, or as multiple full bandwidth Auxiliary Outputs. The default configuration for the PLM is2 x 2-Auxiliary Output Modules, providing a total of four Module outputs.Please refer to the Lake Controller Operation Manual for further information.6.4.2 LoadLibrary™ and FingerprintsIn addition to the standard loudspeaker presets (Module files), the Lake Controller also includes a set ofenhanced Module files specifically for use with the PLM Series.These supplementary PLM Module files, known as the LoadLibrary incorporate both Lake DSP parametersalong with PLM specific data; LoadLibrary Module files include parameter settings for the PLM’s AmplifierGain and ISVPL limiter. Additionally, LoadLibrary loudspeaker types may also include data relating to theelectrical 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-specificloudspeaker type is loaded, its Fingerprint load characteristics are included. These load characteristics arestored in a file with a “.mdl” suffix and are loaded simultaneously with the module file.6.4.3 Super ModulesSuper Modules allow control of multiple Modules of the same type, distributed across multiple Frames, asa single entity within the Lake Controller software. A change made in the Super Module is replicated acrossall assigned Modules, resulting in improved efficiency in system configuration and a reduction of on-screenicons within the Lake Controller software.The key benefit of this feature is the ability to connect and control crossovers, levels and EQ across multiplehardware devices simultaneously from the Lake Controller. For example, one device may be driving sub andlow-frequency speakers, while another device controls mid-range and hi-frequency drivers. Using a singleadjustment 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.
