Notes:
(1) Bassand Treble response see attached diagram (fig.16). The center frequency andquality of the resonance behaviour can be choosen by
the external circuitry. A standard first order bassresponse can be realized by a standard feedbacknetwork
(2) The selected input is grounded thru the 2.2µF capacitor.
