• Speaker Distance (Speaker distance)
Use this feature to manually input the distance of each
speaker and adjust 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 sound will arrive at the listening position at the
same time.
