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.
