4.4 Equalization
From the LEVELS interface, tap the EQ tab in the top-left corner of the display to move to the EQ controls
for the Module. Parametric EQ (PEQ) is displayed by default.
Figure 4-31: PEQ tab with EQ filter tools and options
Multiple EQ overlays are identified by tabs at the top left of the display. A three-way Module initially has one
parametric (PEQ1) and one graphic (GEQ2) overlay, in addition to the XOVER tab. A Mesa EQ Module has a
tab labeled HPF/LPF instead of XOVER.
The parametric overlay (PEQ) provides low-shelf, parametric, Mesa, and high-shelf filters. The graphic
overlay (GEQ) provides third-octave EQ controls. The XOVER screen allows selection and adjustment of
crossover filters, in addition to output EQ.
4.4.1 EQ Overlay Store/Recall
EQ Overlays can be stored and recalled, either to an existing EQ Overlay which will replace the current EQ
Overlay content or by Recall as New to add an additional EQ Overlay. Both Parametric (PEQ) and Graphi
(GEQ) Overlays can be stored and recalled to and from Modules and Groups.
When an EQ Overlay is stored or recalled, the path to where it was stored or recalled from is stored by the
Module or Group. This allows preparation of option folders for Modules or Groups to customize EQ depend-
ing on, for example, overall coloration or speaker hanging attributes.
The path is relative the Modules and EQ Overlay folder, so will function correctly for migrated files (i.e. the
path information will always resolve to current Lake Controller version after a software upgrade). If an EQ
Overlay file is stored outside the Modules and EQ Overlay folder, the path will not be stored in the module
for that Overlay.
The path for different EQ Overlays in Modules and Groups are also stored in the System file however the
path is not stored in the frame. E.g. recalling settings through a FramePreset recall, Use Data In Processors
or frames taken from scrollbar to workarea will not contain path information to EQ Overlays.
4.4.2 Graphic EQ
1. Tap the GEQ2 overlay to access the default third-octave graphic overlay. The bottom section of the
graphic EQ screen contains the EQ Tool, which is used to select a frequency band for gain adjustment.
