1. Bass and Treble response see attached diagram (fig.22). 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.
