Figure 8.2. Overview. All 5 lines start far apart at 10 hz. As frequency increases they get closer together, slowly at first and then more rapidly. When they get quite close they come together more slowly again. They merge into a single line and then diverge again. Moving apart slowly at first then more rapidly and slowly again as they approach 100 kHz.

Numerical values. I will give the Values in dB for only the two frequencies of 10, and 35 kHz. I will state only the values. It is up to the reader to keep track of the frequency for each point as it is given. The reason for using 35 instead of 100 kHz will be stated below.

I will give the values in dB for each line in sequence. Green, blue, red, light blue, and purple. Starting out at 10 Hz the values are, minus 15, minus 6.5, minus 0.5, plus 5.5, plus 13. Due to high frequency roll off in the feedback amplifier the values will be given at the peak frequency which is 35 kHz. The values are, minus 14.5, minus 6.5, minus 1, plus 5, and plus 12. The roll off effect is greatest for the max boost line, purple, about 1/2 dB for the tone flat line, red, and nonexistent for the max cut line, green. End verbal description.
