The BA3888S is a sound processor IC that performs 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) Corrects 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 can be set in the range 0dB to 9dB (Typ.) using external components.
5) A noise gate circuit naturally cuts hiss at low volume.

Applications
    VCRs, tape recorders and video equipped television
