The Listener Position menu is used for setting the rear and center delays and
calibrating the Panorama effect.
When presented with several similar sounds (as in the case of surround
sound) we tend to localize on the first sound we hear. Because rear speakers
are often closer to the listening area than the main speakers, occasional
leakage of the front channel sound into the surround speakers can be
audible and distracting. Delaying the sound from the rear speakers gives
the sound from the front speakers a chance to reach the listener before the
surrounds kick in. The REAR DELAY control in the Listener Position menu
allows the user to set the rear delay between 15 and 30 milliseconds in one
millisecond increments. The best setting will depend on the distance
between the main listening area and the front speakers as well as the
distance between the main listening area and the surround speakers. This
global rear delay setting is used by surround effects that do not have their
own rear delay setting.
