Delay Settings
One aspect of the surround modes is the
delay of audio signals between the front
speakers and the rear speakers. Each
surround mode is factory preset with a
specific delay time, but it is possible to
individually adjust the delay timing to
custom tailor the sound to your individ-
ual taste and the acoustic conditions in
your listening room or home theater.
The factory setting is appropriate for
most rooms, but some installations
create an uncommon distance between
the front and surround speakers that may
cause the arrival of front channel sounds
to become disconnected from surround
channel sounds.
To resynchronize the front and surround
channels, follow these steps:
1. Measure the distance from the
listening/viewing position to the
front speakers.
2. Measure the distance from the
listening/viewing position to the
surround speakers.
3. Subtract the distance to the surround
speakers from the distance to the
front speakers.
a. When setting the delay time for the
Dolby Digital surround mode, the
optimal delay time is the resulting
figure. For example, if the front
speakers are ten feet away and the
surround speakers are five feet
away, the optimal delay time is
figured as 10–5=5. Thus, in this
example, the delay should be set at
five milliseconds.
b. When setting the delay time for
the Pro Logic mode, take the result
of the subtraction and add 15 to
obtain the optimal delay time. For
example, if the front speakers are
ten feet away and the surround
speakers are five feet away, the
optimal delay time is figured
as 10–5+15=20. Thus, in this
example, the delay should be set
at twenty milliseconds.
To set the delay times, follow these steps:
1. Put the AVR5 in the Dolby Pro Logic
mode by pressing the Dolby Pro
Logic Selector * on the front
panel, or by pressing the Surround
Mode Selector on the remote,
until PRO LOGIC appears in the
Information Display ¯ and the
PRO LOGIC indicator lights.
2. Press the Delay button < Ù on
the remote or front panel. The word
DELAY 20 will appear in the
Information Display ¯ .
3. Adjust the delay time by pressing the
Delay button < Ù on the remote
or front panel until the delay time fig-
ure closest to the number calculated
using the formula entered above
appears in the display.
4. Once the desired setting appears, do
not press the button again; the unit
will return to normal operation in
five seconds.
Congratulations! You have now completed
the setup, adjustment and calibration of
the AVR5. You are now ready to enjoy the
finest in music and home-theater listening.
