Question:

What is Auto Volume and how does it work?

Answer:

Subject:  Auto Volume

The Auto Volume feature is for channel to channel sound stabilization.

When the feature is turned on, it helps with volume fluctuations when changing channels.

This prevents a dramatic increase or decrease of the decible level of the audio from the TV speakers.

Note:

This feature has no effect on the in-channel differences.

For example: 

When watching a show that jumps to commercial, the commercial is 1 or 2 times louder than the normal broadcast.

The feature will have no effect on this situation
