Notes:
(1) The circuit can be supplied either at VS1 or without the use of the internal voltage regulator at VS2 . The circuit also operates at a supply
voltage VS1 lower than 10V. In this case the ripple rejection of VS2 is valid, because the voltage regulator saturates to a saturation voltage
of about 0.8V.
(2) The selected input is grounded thru the 2.2µF capacitor.
(3) Bass and Treble response see attached diagram. The center frequency and quality of the resonance behaviour can be choosen by the
external circuitry. A standard first order bass response can be realized by a standard feedback network.
