The internal LakeProcessing includes programmable crossovers, EQ, dynamics and other functions, and can be fully con-trolled via the supplied Lake Controller software. Additionally, many functions can be controlled or accesseddirectly via the front panel.The Lake Controller Operation Manual and Lake Network Configuration Guide are supplied on the accompa-nying CD ROM and additional documentation is available from the Start Menu after software installation.6.3 Modules and Frames6.3.1 OverviewA Frame represents one physical Lake Processor (e.g. a PLM or LM 26). 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.
