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 lter tools and options

Multiple EQ overlays are identied 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 lters. The graphic

overlay (GEQ) provides third-octave EQ controls. The XOVER screen allows selection and adjustment of

crossover lters, 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 les (i.e. the

path information will always resolve to current Lake Controller version after a software upgrade). If an EQ

Overlay le 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 le 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.
