FCircuit operation
(1)
The LINE and REC input circuits are configured as differ-
ential amplifiers, and the gain can be set to any desired
value using an external resistor. The input impedance is
determined by the external resistor.

A bias voltage of V
Since the output stage uses a push-pull configuration, a
stable bias source can be obtained.
(3)
This is a circuit that selects the required frequency com-
ponent from the input signal and amplifies it. With this
configuration, no external capacitor is needed. In addi-
tion, the center frequency is set based on the current, so
