Audio ICs BBS (bass boost system) for radio cassette players BA3870 The BA3870 is a bass boost audio IC for radio cassette players. BBS adjusts the base boost to a level appropriate for the volume, achieving a rich sound without distortion. Frequency characteristics can be set externally, enabling system design to meet the needs of the application. FApplications Radio cassette players FFeatures 1) Adjustment of the base boost to a level appropriate for the volume through BBS. 2) Maximum bass boost level can be set externally. (20dB recommended) 3) Treble boost circuit (constant at 4dB) included onchip to preserve overall balance. 4) BBS on / off “pop” sound almost nonexistent.
