9.5.4 Linear Phase Brick Wall 4-Way
The Linear Phase Brick Wall 4-Way (LP4way) uses the processing power of two Modules to create extra-
steep crossovers.

9.6 FIR Module [Lake-enabled Amplifiers Only]
Lake-enabled amplfiers (PLM, PLM+ and D Series) support the FIR Module type, which incorporates a
combination of FIR and IIR technology. The extensive FIR filters can be used to create both crossovers and
driver EQ. The phase can be absolutely controlled rendering linear phase, minimum phase, or arbitrary phase
filters. The IIR filters can be used to create classic crossovers and specific driver EQ.
FIR modules supports EAW Focusing through direct import of EAW greybox files into the Lake Controller.
The latest EAW greybox files can be downloaded via: http://www.eaw.com/downloads/
9.6.1 FIR 1-Way [Lake-enabled Amplifiers Only]
The FIR 1-Way (FIR1) is a FIR/IIR processing program that uses the processing power of two Modules. This
program is activated by recalling an FIR Module or by recalling an EAW Greybox (.gyx) file.
