4.4.4 EQ Overlays
The concept of EQ overlays is another innovative Lake feature. Tap the PEQ1 tab at the top of the screen.
PEQ1, BLEQ2 and GEQ3 are all different EQ overlays. The white line represents the composite response
of all EQ overlays, including those from the Module and Overlays from all assigned Groups. A grey line, if
visible separate from the white line, indicates the EQ response for the selected overlay only.
With the PEQ1 screen selected in Figure 4-1 on page 27, the white line (composite curve) indicates the
wide band 6 dB boost created in the GEQ3 overlay. The next section illustrates how multiple EQ overlays
interact.
4.4.5 Parametric EQ
To add a Parametric lter to the PEQ1 overlay:
1. Tap the Parametric lter at top of the EQ display.
2. Tap the screen near 125 Hz to insert the lter there.
