Bass Boost Function (BSTO, BSTN, BSTC)
Using the bass boost function, the left-channel and right-channel bass components are sampled and ampliï¬ed,
or boosted, and added to the headphone driver ampliï¬er. The connection of 0.1µF (std) capacitor to BSTC
forms a lowpass ï¬lter. The bass boost response can also be selected using bit D12.
Usually there is no component connected to BSTO and BSTN, however, the boost response characteristic can
be modiï¬ed by connecting a resistor and capacitor between BSTO and BSTN.
