The plot at the bottom now has the thick solid white line at the bottom indicating that the curser is over the stage area. The
frequency response graph at the top shows two traces. The dashed yellow line is the response at the reference position indicated
by the dashed black line on the index plot. The blue response is on stage where our curser position has been placed. It is easy to
see from these how the colours respond to the peaks and troughs on the graph. The on stage response for example has little or
no high frequency, it is not even registering anything above around 2.5KHz, on the index plot it is an even band of blue in this
region. The response at the reference position is reasonably flat in the low frequencies, gradually tapering off as the frequencies
increase. On the index plot we see a block of orange which gradually fades through yellow, green and indigo to blue at the highest
frequencies.
We can now look at an optimised system, this is what a perfect system would look like if it wasn’t for little inconveniences such
as the laws of physics, the impossible dream of perfect coverage at all frequencies for the entire audience with no spill
whatsoever anywhere else;-
