2.4.12 Channel delay set-up
Set-up of time delay in the surround
channel
Usually, time delay in the Dolby Digital
decoding system is preset to ensure best effect
while installing the Home Theater. However, in
case you wish to adjust your system more
precisely, please consult instructions given in
this manual. Set up of time delay for this device
is possible in both Dolby Digital and Dolby Pro
Logic modes..
To Set the desired delay you have to know the
distance from the place where you are ,to the
front speakers and Surround speakers as shown
in Fig. 1Consult Fig.2(Dolby Pro Logic mode)
and3(Dolby Digital mode) in order to determine
the distance to Surround speakers(axis Y in the
figure) and the distance to the front speakers
(axis in the figure).Crossing point of those two
lines on the chart will give the recommended
delay value.
Fig.1.Take into account the A-B distance; use both
figures for setting the desired time delay.

Set-up of time delay in the central
channel
Sometimes several people are listening to
the music, and the space is limited. In this case,
you can install three speakers(two front ones
and a central one) as shown in Fig.1 with the
distance to the listener being approximately the
same. The central channel delay is to be set at
“0”.
Should the central speaker be in close
proximity to left and right front speakers as
shown in Fig. 2, or the central speaker be
nearer to listeners when compared with front
speakers’ location, or the central speaker be
nearer to the listener by 1 foot, in all these
cases you may set the delay value for the
central channel at 1 ms.
For instance, as shown in Fig.2, if the line C
is by 1 foot shorter than the lines R and L, the
delay value is to be set at 1 ms. If your sofa is
broad enough, and there are several listeners
sitting on it , it makes sense to locate the
speakers in one line, as shown in Fig.3 with the
delay value of the central to be set at “0”.
Finally, if it will be necessary to install the
central speaker behind the left and right front
speakers, the delay value shall be set at “0”.
