Vocal Fader Ic - Rohm

The BA3837 BA3837F and BA3838F are ICs with 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. By ROHM Co. Ltd.
