BA3880AS / BA3880AFS

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.

!Applications

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

!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.
