NOTES:

(1) Bass and treble response see Figure 16. The center frequency and quality of the response behavior can be

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

network.

(2) The selected input is grounded through the 2.2

µF capacitor.
