AVLS (Automatic Volume Limiter System)

Set the maximum volume level for headphones. This can help prevent sound from escaping from the headphones as well as the possible danger resulting from being unable to hear what is going on around you when wearing headphones.

Off Does not set a limit; allows for the volume to be adjusted manually
On Sets a limit on the volume

Notice

Exercise care when setting the volume. If you set the volume too high, it may harm your hearing or damage the speakers.
