Night Mode Settings
The Night mode is a feature of Dolby Digital that
uses special processing to preserve the dynamic
range and full intelligibility of a movie sound
track while reducing the peak level. This prevents
abruptly loud transitions from disturbing others,
without reducing the sonic impact of a digital
source. Note that the Night mode is only avail-
able when the Dolby Digital surround mode is
selected.
To adjust the Night mode setting from the
menu, make certain that the
cursor is on the
Night line of the SURROUND SETUP
menu. Next, press
buttons
/
choose between the following settings.
OFF: When OFF is in the highlighted video,
the Night mode will not function.
MID: When MID is in the highlighted video, a
mild compression will be applied.
MA X: When MAX is in the highlighted video, a
more severe compression algorithm will be
applied.
When you want to use the Night mode feature,
we recommend that you select the MID setting
as a starting point and change to the MAX set-
ting later, if desired.

Output Level Adjustment
Output level adjustment is a key part of the con-
figuration process for any surround sound prod-
uct. It is particularly important for a Dolby Digital
on
receiver such as the AVR, as correct outputs will
on the
ensure that you hear sound tracks with the
proper directionality and intensity.
.
NOTE: Listeners are often confused about the
operation of the surround channels. While some
assume that sound should always be coming
from each speaker, most of the time there will
be little or no sound in the surround channels.
This is because they are only used when a
movie director or sound mixer specifically places
sound there to create ambiance, a special effect
or to continue action from the front of the room
to the rear. When the output levels are properly
set it is normal for surround speakers to oper-
ate only occasionally. Artificially increasing the
volume to the rear speakers may destroy the
illusion of an enveloping sound field that dupli-
cates the way you hear sound in a movie the-
to
ater or concert hall.
IMPORTANT NOTE: The output level can be
adjusted for each digital and analog surround
mode separately. This allows you to compensate
for level differences between speakers, that may
also vary with the surround mode selected, or to
increase or decrease the level of certain speakers
intentionally, depending on the surround mode
selected. Note that adjustments made for any
surround mode are effective with all inputs asso-
ciated with the same surround mode.
Before beginning the output level adjustment
process, make certain that all speaker connec-
tions have been properly made. The system
volume should be turned down at first. Finally,
make certain that the Balance Control
set to the center "12 o'clock" position.
Using EzSet
Harman Kardon's exclusive EzSet remote makes
it possible to quickly and accurately set the
AVR 3550's output levels without the use of a
sound pressure meter, although manual adjust-
ment is also available. However, for the easiest
set-up, follow these steps while seated in the lis-
