BST SW
Boost on/off switch
BST on: H level or open
BST off: L level
Refer to application note 3 (2)
This switch is the control terminal of
the bass boost function. When it is
synchronized with treble boost
function, the external connection with
the PW NF terminal is required. Refer
to application circuit.
