Considering an increasing frequencystarting from some arbitrarily low value, the "gain" of the circuit is initially the same as an unbypassed cathode circuit.
假定从一个相当低的频率开始逐渐上升，这个电路的增益在开始的时候会和阴极电阻没有旁路的电路一致。

Starting with your eq flat, remove ALL be bottom end by turning the lowfrequency control to full cut.
