BH3874AKS2 General Description
The BH3874AKS2 is a sound control IC for mini-component stereo. 4-ch input selector, vocal fade, volume, surround, 5-band graphic equalizer, dynamic bass, and 5-band spectrum analyzer are integrated into a single chip. Soft switch can reduce the switching noise occurred when volume, vocal fade, surround, and dynamic bass are switched.
BH3874AKS2 Features
1) A single chip IC integrates all functions of volume, tone control, and spectrum analyzer.
2) Soft switching can reduce the noise occured when volume, mode selector, surround, dynamic bass, and gain of
graphic equalizer are switched.
3) 4-ch input selector, mode selector, volume, surround, graphic equalizer, dynamic bass, and spectrum analyzer.
4) Built-in matrix surround, pseudo stereo circuit, and band pass filter for spectrum analyzer.
5) Low distortion and low noise due to the BiCMOS process adopting resistance ladder volume.
6) Filters of dynamic bass and biamp can be set freely by the combination of LPF and HPF.
2) Soft switching can reduce the noise occured when volume, mode selector, surround, dynamic bass, and gain of
graphic equalizer are switched.
3) 4-ch input selector, mode selector, volume, surround, graphic equalizer, dynamic bass, and spectrum analyzer.

5) Low distortion and low noise due to the BiCMOS process adopting resistance ladder volume.
6) Filters of dynamic bass and biamp can be set freely by the combination of LPF and HPF.
BH3874AKS2 Typical Application
Mini component stereo, Micro component stereo, CD radio cassette players, and TV.
BH3878KS2 General Description
BH3878KS2 is a sound controller IC for mini component stereo. 5-channel input selector, vocal fader, volume, surround, 5-band graphic equalizer, dynamic bass, and 5-band spectrum analyzer are all integrated into this single chip. Switching noise is reduced when volume, vocal fader, surround and dynamic bass are changed by soft switch.
