As shown in the figure, there are two turning frequencies: the turning frequency that starts to decay is ≈1/27rC3 (Ri+
R2); the turning frequency that changes from attenuation to flat is, LI. l/2rTC3RP2. Combining the frequency characteristic curves
under the four extreme conditions of treble boost, treble attenuation, bass boost, and bass attenuation, the
total characteristic curve is formed as shown in Figure 1-63 .
