Signal Flow and Lake Processing15Lake LM Series Operation Manual Rev 1.3.55.7 Switching between Contour and Mesa ModeWhen switching between Contour and Mesa Modes, all current Frame configuration data is lost (Presetsare retained) and the device is completely reconfigured into the selected Mode. Ensure you have stored anyexisting frame configuration data before configuring into a different mode.The device configuration may be changed either via the Front Panel MENU > FRAME > FRAME RST (referto section 6.10.4.2) or via the Lake Controller MODULES > I/O CONFIG > FRAME CONFIG menu (refer tothe Lake Controller Operation Manual).5.8 Files and PresetsThe Lake system provides various methods for storing and recalling Module, Frame, or system-wide data.An overview is provided below; for further information please refer to the Lake Controller Operation Manual.5.8.1 Module, System and Sub-System Configuration FilesModule, System and Sub-System Configuration files are stored on the Lake Controller PC, and data ispassed across the network when recalling or storing these type of files.▸ A Module file is the smallest set of data that can be stored and recalled; it contains crossover, gain,delay, and limiter information for an individual loudspeaker (i.e. the data shown in red in the signal flowdiagrams in section 5.1). A Module file may be recalled into other Lake devices. It is not possible tostore a Module File directly on the hardware device.▸ A System or Sub-System Configuration File contains a set of Module file information in addition toFrame related information such Group data and I/O configuration (i.e. the data shown in blue in thesignal flow diagrams in section 5.1).5.8.2 Frame and System PresetsThe entire processor configuration can be stored as a Frame Preset on this hardware device. Presets canbe recalled via the front panel (refer to section 6.10.6) or via the Lake Controller software or Preset Managerutility; 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 includes theconfigurations of all Modules in the Frame, including levels, crossover, EQ, input mixer, routing, and all otherparameters. As Frame Presets are stored in the hardware device, recall is available without using a PC.Using the System Presets function in the Lake Controller, entire system configurations can be stored andrecalled across a network of LM & PLM Series devices. This enables fast retrieval and switching of entiresystem configurations as minimal data is being sent between the Controller and Processors.
