Notes:

(1) Bass and Treble response see attached diagram (fig.17). 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.

(3) Condition obtained programming: mute on speaker attenuators (1X111111) followed by selection of SECMUTE (1XXXX111).
