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.

4) Internal microphone ON / OFF switch.

5) Vocal detection.

6) Internal microphone ALC function.

7) Internal anti-popping circuit.

3) Echo level and loop ratio are DC-adjustable with the

internal electronic volume control (EVR).
