Rear Delay Settings

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 a chance to reach the listener before the surrounds
kick in.

The REAR DELAY control in the LISTENER POS menu allows you to set
this delay at 15-30 milliseconds. The best setting will depend on the distance
between the main listening area and the front speakers, and the distance
between the main listening area and the surround speakers.

From the Setup menu. press PARAM to select "LISTENER POS", then press
PARAM ▲ to display the LISTENER POS menu. Now use PARAM to select
REAR DELAY, then use PARAM ▲ and ▼ to adjust the delay time.

Refer to the graph shown at the right for the best setting for your particular
situation. Measure the two distances and note where they intersect on the
graph. The shaded areas indicate the optimum delay settings.

Note that the delay setting you choose here will only affect those surround
modes which do not have their own rear delay parameter.
