9.6 FIR Module [Lake-enabled Ampliers Only]
Lake-enabled amplers (PLM, PLM+ and D Series) support the FIR Module type, which incorporates a
combination of FIR and IIR technology. The extensive FIR lters can be used to create both crossovers and
driver EQ. The phase can be absolutely controlled rendering linear phase, minimum phase, or arbitrary phase
lters. The IIR lters can be used to create classic crossovers and specic driver EQ.
FIR modules supports EAW Focusing through direct import of EAW greybox les into the Lake Controller.

9.6.1 FIR 1-Way [Lake-enabled Ampliers 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) le.
