Overview
Multimedia ICs 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 commercially available music software) all on one chip.
2) Has internal secondary active LPF to enable a highdegree 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) 5) 6) 7) Key controller input and internal switches.
Internal microphone amplifier.
Low noise and low distortion.
Few external components.
