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.
