BA7726AFS General Description
The BA7726AS and BA7726AFS are analog companders for karaoke echo systems and have internal logarithmic compression and expansion circuits, a stereo line mixer amplifier, vocal fader function, vocal detection function, microphone ALC, microphone ON / OFF switch, and output switch. When used together with the BU9252 8-bit digital delay, these ICs form a high-grade karaoke echo system with minimum components.
