Overview
The LC75106V is a digital echo LSI for karaoke. It has the microcomputer control mode (I2C BUS control) and non-
control mode. Therefore, various karaoke systems can be made.
This LSI has 2ch mic amplifier (with ALC), volume of 2ch mic, echo feed back volume and echo volume.
In addition, when the stereo signal internal connected mode has the function of the vocal cancellation etc.
The karaoke system can be constructed with this LSI.
Functions
2ch mic amplifier (with built-in Auto Level Control)
Volume of 2ch mic
With built-in for digital echo memory 32kbit
Feedback volume for digital echo
Digital echo volume
Mic mixing function
Vocal cancellation
With built-in oscillation circuit
I2C bus control
Application
Mini component audio and other
