1. Bass and treble response see attached diagram (Figure 19). The center frequency and quality of the resonance behavior
can be chosen by the external circuitry. A standard first order bass response can be realized by a standard feedback
network
2. The selected input is grounded through the 2.2 µF capacitor.
