NIPPON PRECISION CIRCUITS—15
Bass Boost
Two types of bass boost and gain modification can be
set by either parallel or microcontroller.
Bass boost detection output
With microcontroller setting (when P/M is LOW),
the 21st pin is the BBON output pin and functions as
output that detects the bass boost mode.
BBON output is LOW when the bass boost mode is
set to Flat 1 and HIGH in all other cases.
