The BD3881FV incorporates a sound controller with
built-in EQ for playing and recording of cassette tape
recorder. When the tape recorder is not used, the
equalizer can be used as an ordinary input selector.
The sound controller block is simply composed of
2-band tones and volume.
The BD3882FV incorporates rear volume for improving
SN and 3-band tones. The BD3882FV has nearly the
same pin assignment as the BD3881FV and both can be
used in a variety of applications.
