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 available
when the Dolby Digital surround mode is selected.
To adjust the Night mode setting from the menu

press the OSD Button
menu appears. Then press the

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
setting later, if desired.
Note that the Night mode may be adjusted
directly any time that Dolby Digital surround

AVR 645.
Using EzSet/EQ
The AVR uses Harman Kardon's EzSet/EQ tech-
¤
nology to automatically configure your system to
deliver the best possible performance based on
Q to
your specific speaker selection, where the speak-
menu. Press
ers are placed in the room and the acoustic influ-
ences in your listening room. By using a series of
test signals and the processing power of the
Texas Instruments DA 610 digital signal proces-
line of the
sor, EzSet/EQ eliminates the need for manual
adjustment of speaker "size", crossover, delay
and output level settings while it adds the power
of a multi-band parametric equalizer to smooth
out the frequency settings for optimal sound
reproduction.
In addition to making system setup quick and
easy, EzSet/EQ is more precise than manual
settings. With EzSet/EQ you are able to calibrate
your system in a fraction of the time it would
take to enter the settings manually, and with
results that rival those achieved with expensive
test equipment and time consuming procedures.
The end result is a system calibration profile that
enables your new receiver to deliver the best
possible sound no matter what type of speakers
you have or what the dimensions of your
listening room are.
We recommend that you take advantage of the
precision of EzSet/EQ to calibrate your system,
but if desired you may also make any of the
configuration settings manually, or trim the
settings provided by EzSet/EQ by following the
instructions on pages 32-35.

and press the Set Button
Before starting the EzSet/EQ process, make cer-
tain that you have connected all speakers for
your system and that you have both the EzSet/EQ
microphone and the extender rod handy. If you
have a standard camera tripod, attach the exten-
der rod to the tripod, and then screw the micro-
phone to the top of the rod. Place the tripod at
your primary listening position, at least one
meter from the nearest speaker and adjust it so
that microphone is at least one meter above ear
level. If you do not have a tripod, simply screw
the extender rod into the bottom of the EzSet/EQ
microphone.
Next, plug the microphone into the EzSet/EQ
Microphone Jack ˘ located behind the Front
Panel Control Door. The microphone cable is
approximately 6 meters long, which should
accommodate most listening room situations. If
required, you may use an optional extension
cable, available at most electronics stores, for use
in larger rooms. However, we recommend that
you make every effort to avoid using extension
cords for the microphone cable as they may
adversely affect the test results.
Finally, before going further, make certain that
the program volume is at -35dB. If there is a
volume or "level" control on your subwoofer,
make certain that it is set to at least the mid-
point, if not a bit higher
You are now ready to start the EzSet/EQ process
by following these steps:
Step 1. Navigate to the
EZSET/EQ MODE
menu (Fig. 17a) by first pressing the OSD
Button
