Operation
Setting the Surround Delay
For Dolby Surround AC-3, as opposed to
the conventional Dolby Pro Logic technol-
ogy, it is unnecessary to set the time delay
between front speakers and surround
speakers. The only thing you should
consider is the difference between the front
speaker-listener distance and surround
speaker-listener distance.
1. Press the DELAY TIME button
repeatedly until the desired
delay time is displayed.
The factory-set default is 5 ms (millisec-
onds). Each time the DELAY TIME button
is pressed, the time increases by 1 ms. You
can set a delay time within the range of 0
to 15 ms.
A rule of thumb is that it takes 1 ms for
sound to travel one foot. For example, if
the front speakers and the surround
speakers are located the same distance
from the listening position, you should set
the delay time as “0”; If the front speaker-
listener distance is one foot longer, set the
delay time to “1 ms” and so on.
Note:
· If your surround receiver’s delay time
has been accurately set for Dolby Pro
Logic Surround play, make the ED-
901’s delay time 15 ms shorter than
that time.
· If you have changed the speaker
arrangement, change the speaker
output setting as appropriate both on
the ED-901 and on the surround
receiver. The settings of these two are
independent of each other.
