Bass Boost Function (BSTO, BSTN, BSTC)

Using the bass boost function, the left-channel and right-channel bass components are sampled and amplified,

or boosted, and added to the headphone driver amplifier. The connection of 0.1µF (std) capacitor to BSTC

forms a lowpass filter. 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 modified by connecting a resistor and capacitor between BSTO and BSTN.
