■ Distance (Speaker distance)
Use this feature to manually adjust the distance of each
speaker and the delay applied to the respective channel.
Ideally, each speaker should be the same distance from the
main listening position. However, this is not possible in most
home situations. Thus, a certain amount of delay must be
applied to the sound from each speaker so that all sounds will
arrive at the listening position at the same time.

parameter.
Initial setting: Feet (U.S.A. and Canada models)
