h an internal secondary active LPF for vocal cancellation functions and mixing amplifier functions with high degrees of vocal cancellation. Three control pins are used to switch between modes: the key controller input mode, through mode, vocal fader mode, sound multiplexing mode and mute mode. By offering these functions on a single chip, these ICs can significantly reduce the number of external components. Applications • Karaoke functions on stereo systems, portable stereos and VCRs Features • 1) Single-chip IC with vocal fader, to erase vocals from commercially available recordings. 2) Internal secondary active LPF for h
