Module File Types & Lake LoadLibrary™
9. Module File Types & Lake LoadLibrary ™
Lake devices provide two categories of Modules; Contour Modules and Mesa Modules. Contour Modules
are suitable for devices that can perform loudspeaker crossover functionality, and Mesa Modules are
suitable for devices that provide equalization only.
This chapter provides a detailed reference for all Lake Module file types. Default Module files are located in
the Default Modules folder and can be accessed and recalled utilizing the MODULE STORE/RECALL menu.
9.1 Module Types Overview
Within the Contour Module category, there are four distinct types of Module:
1. Classic Crossover Modules (featuring Bessel, Butterworth, and Linkwitz-Riley crossovers, available with
roll-off ranging from 6 dB/octave to 48 dB/octave).
2. Auxiliary Output Modules (provides EQ only functionality with a single input mix to multiple outputs
when in Contour Mode).
3. Linear Phase Crossover Modules (providing zero phase distortion with steep transition slopes using FIR
filters).
4. FIR Modules (combination of FIR filters, Classic crossovers, and output-specific driver EQ) - only
available on Lake-enabled amplifiers by recalling an FIR Module, or via the import of EAW ® Greybox™
files (.gyx), providing support for EAW Focusing.
The MESA EQ Module category provides a signal Module type of MESA EQ, that it defaulted for use as a
single input to single output, full bandwidth EQ Module and also provides HPF/LPF functionality.
9.2 Supplementary Module Data
Any Module file may contain additional parameters relating to the power output stage, including Amplifier
Gain and ISVPL™ limiter. These parameters are used when the file is loaded into a Lake-enabled amplifier
and ignored when loaded into another Lake device; these parameters are retained and passed through to
new Module files via the Module/System Store commands.
Additionally, loudspeaker electrical characteristic parameters (termed Fingerprint and used for LoadSmart™
verification) are stored and recalled via a supplementary “.mdl” file with the same filename. This Fingerprint
file must be present in the same directory as the Module file; it is stored and recalled for Lake-enabled
amplifiers, and ignored for other Lake devices. Fingerprint data may be reconnected with a Module file
simply by renaming or moving the mdl file to ensure it has the same filename and directory location as its
associated Module file.
