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 le types. Default Module les 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 ve 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
lters).
4. FIR Modules (combination of FIR lters, Classic crossovers, and output-specic driver EQ) - only
available on Lake-enabled ampliers by recalling an FIR Module, or via the import of EAW
®
Greybox™
les (.gyx), providing support for EAW Focusing.
5. XP Modules (can be used for both Auxiliary and Crossover use, combining FIR lters and classic Bessel,
Butterworth and Linkwitz-Riley LPF/HPF available with roll-off ranging from 6 dB/octave to 48 dB/oc-
tave and output-specic driver EQ, Multiband Limiter, Pre-Output EQ with ALL-pass lters. Also offers
Array-optimization capability and integration).
To create advanced Speaker Presets, there is also a custom control interface available for additional
conguration. Contact Lab.gruppen support for more information.
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 le may contain additional parameters relating to the power output stage, including Amplier
Gain and ISVPL™ limiter. These parameters are used when the le is loaded into a Lake-enabled amplier
and ignored when loaded into another Lake device; these parameters are retained and passed through to
new Module les via the Module/System Store commands.
