Auto Volume
Screen Menu > Sound > Speaker Settings > Auto Volume Try Now
Because each station has its own set of broadcasting conditions, the volume may fluctuate as the channel changes. The Auto Volume function automatically adjusts the volume of a channel by lowering or raising the sound output. Normal applies a normal level of volume adjustment, whereas Night applies a slightly lower volume level than Normal and is ideal for nighttime TV viewing. To use the volume control of a connected source device, deactivate the Auto Volume function. When using the Auto Volume function with a source device, the device’s volume control may not function properly.
