What do the letters AVC represent in a basic schematic?

The letters AVC stand for Automatic Volume Control. This technology is designed to automatically adjust the volume level of audio signals to maintain a consistent output level, improving the listening experience by preventing sudden changes in volume. This is particularly useful in environments where audio levels can vary greatly, such as in broadcasts or live performances. By implementing Automatic Volume Control, the system minimizes the effort required by the user to manually adjust volume levels, thereby allowing for a smoother auditory experience. This function is commonly found in various audio equipment, from televisions to audio processing devices.
