The BA3880AS and BA3880AFS are sound processor ICs that perform phase and harmonic compensation on audio signals to accurately reproduce the "rise" section of audio signals that determines the characteristics of the sound, and thus reproduce the original recording as naturally as possible.

FEATUREs
1) Correct distortion in the rising section of audio signals
   that results from miss-matched speakers and amplifiers, and
   reproduces the original sound faithfully.
2) To allow application with all types of speakers and sources,
   the clarity can be adjusted using DC control.
3) DC control provided for selection of either processor mode or bypass mode.
4) Bass boost fixed internally to 4dB.

APPLICATIONs
   Component stereo systems, radio cassette players,
   car stereo systems, televisions, VCRs, and active speakers.
