4.4.4 EQ Overlays
The concept of EQ overlays is another innovative Lake feature. Tap the PEQ1 tab at the top of the page.
GEQ2 and PEQ1 are two different EQ overlays. The white line represents the composite response of all EQ
overlays. It now shows the wide band 6 dB boost created in the GEQ2 tab. In the next section, we will see
how multiple EQ overlays interact.
4.4.5 Parametric EQ
To add a parametric filter to the PEQ1 overlay:
1. Tap the parametric filter at top of the EQ display.
2. Tap the screen near 125 Hz to insert the filter there.
