BA3836

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.
