Multimedia ICs
Analog compander with vocal fader
for KARAOKE
BA7726AS / BA7726AFS
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.
Applications
Portable CD stereos with karaoke functions, VCRs, mini component stereo systems, LD players
Features
1) Internal stereo line mixer amplifier, allowing selec-
tion of through output, left output, or right output.
2) Internal vocal elimination function, suitable for vocal
faders and left and right output.
3) Echo level and loop ratio are DC-adjustable with the
internal electronic volume control (EVR).
4) Internal microphone ON / OFF switch.
5) Vocal detection.
6) Internal microphone ALC function.
7) Internal anti-popping circuit.
