Notes:
(1) Bass and Treble response see attached diagram (fig.17). 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
(2) The selected input is grounded thru the 2.2µF capacitor.
