of about 0.8V.

(2) The selected input is grounded thru the 2.2

µF 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.
