izer to boost 6 dB at 500; 630; 800; 1,000; 1,250; 1,600; and 2,000 Hz produces the frequency response
shown in Figure 4-34.
Figure 4-34: Conventional Graphic Equalization and Resulting Frequency Response
This measured frequency response is not what you would expect from the graphic EQ controls.
If we use the Lake Controller GEQ overlay to boost 6 dB at 500; 630; 800; 1,000; 1,250; 1,600; and
2,000 Hz, the frequency response is shown by the flat top trace in Figure 4-35.
