Vocal fader IC
BA3836
Realizes karaoke functionality by enabling you to erase only the vocals from commercially available music software.
•^Applications
Mini-components, radio cassette players, car stereos,
karaoke sets
•^Features
1) Vocal fader functions (erase vocals from commer-
cially available music software) all on one chip.
2) Has internal secondary active LPF to enable a high-
degree of vocal cancellation (synchronous rejection
ratio) while retaining the same feeling.
3) Three control pins for switching between 4 modes:
through, vocal fader, sound multiplexing, and mute.
4) Key controller input and internal switches.
5) Internal microphone amplifier.
6) Low noise and low distortion.
7) Few external components.
