The JFET is used as an isolator to boost the input impedance of the op amp to 22 megohms for low frequency input signals. When the frequency is increased to approximately 20 kHz, the impedance drops to 3.9 megohms. When using an 18V supply, the total gain of the circuit is approximately 45 decibels.
