Note: (1) For the Bass and Treble response please, refer to the diagram below. The

center frequency and quality of the resonance behavior can be selected by the external

circuitry. A standard first order bass response can realized by a standard feedback

network.

(2) The selected input is grounded thru the 2.2uF capacitor.
