Delay Time
In the Dolby Pro Logic Surround modes (except 3CH Logic), the receiver
slightly delays the sound going to the rear speakers. You can change
this delay time from 15 to 30 milliseconds (ms) in 5 ms steps. Adjust the
delay time for the best surround effect. As a general guide, each step
corresponds to 3-5 feet in distance. For example, if the surround speak-
ers are 6 feet closer to you than the front speakers, try selecting 20 ms
setting.
Press then hold down
