In figure 48 below, EQs 1, 2, 3, and 4 have been adjusted. The effects of adjusting EQs 2, 3, and
4 can be seen by the deviation from the horizontal line. The effect of adjusting EQ 1 is not seen
because the bypass button for that EQ is still activated and adjustments to EQ 1 are not used to
process the audio signal. The numbers of the EQs contributing to the graph (2, 3, and 4, but not
1) are shown in white against a blue background at the top of the graph.
