!
W
ith the
p
urchase of a Harman Kardon
®
A
VR 645, you are
about to begin many years of listening enjoyment.
The AVR 645 has the most extensive range of audio
a
nd video processing, control and connectivity options
ever offered by Harman Kardon, enabling it to provide
the best possible audio and video reproduction with
any type of source material. Teaming advanced pro-
cessing circuitry with proprietary technologies such as
EzSet/EQ, the AVR 645 seamlessly integrates every
component in your entertainment system to deliver the
best possible sound and images.
Some of the leading-edge features that are available
with the AVR 645, such as HDMI
connectivity and
XM-Ready
®
operation, are new to even the most
experienced home theater enthusiast.
Although the
power of the AVR 645 makes them easy to use, we
strongly recommend that you take a few minutes to
read this owner’s manual to familiarize yourself with
how the full suite of AVR 645 features and capabilities
are configured and used in day-to-day operation. This
small investment of time will yield significant dividends
in taking the maximum advantage of this new addition
to your home theater system.
If you have any questions about this product, its instal-
lation or its operation, you may also access a wealth

Description and Features
The AVR 645 serves as the hub of your home enter-
tainment system, providing a wide range of listening
possibilities for almost any audio or video program
source, whether it is the broadcast of a movie or
sporting event in HDTV or a vintage mono or stereo
recording. When playing digital audio sources from
either the conventional optical and coaxial inputs
,
or
through the
HDMI
1.1 compliant connections,
the
AVR 645 decodes Dolby Digital, Dolby Digital EX,
DTS and DTS-ES data streams. Two-channel stereo
and matrix surround sources benefit from all current
Dolby Pro Logic IIx modes and DTS Neo:6. The latest
version of our proprietary Logic 7
®
process is on-
board to create a wider, more enveloping sound field
and more defined surround channel positioning,
regardless of the type of source material. Additional
audio playback and processing options include a
direct connection to compatible computer-based
sources through a direct USB connection.
The AVR 645 takes the “video” part of its name seri-
ously
.
Along with two HDMI inputs and three 100MHz
a
nalog component video inputs, the AVR 645’s video
p
rocessing allows you to individually adjust the video
processing parameters for each input, and then scale
the output signal to 720p or 1080i to match the
requirements of your specific video display. Tying audio
a
nd video together, the AVR 645 provides A/V sync
delay so that the lip sync errors – commonly seen
when digital video processing is used in a source, pro-
gram or video display – are eliminated.
Thanks to a wide range of multizone options and a
standard ZR 10 remote control, the AVR 645 makes
it possible to watch and listen to a separate source in
one room while the main home theater uses a differ-
ent source. Using the assignable rear surround chan-
nel amplifiers, you may create a basic remote listening
zone without any additional equipment, or the unit’s
multiroom
outputs may be used to feed an optional,
external power amplifier and volume control. For
one-wire multiroom connectivity, the AVR 645 is
A-BUS/
R
EADY
®
, requiring only a single Category 5/5e
cable run and an optional remote module to power a
pair of remote speakers while controlling volume and
enabling full control over the program source and
connected IR-controlled devices.
Along with the latest advances in digital audio and
video technology, Harman Kardon recognizes that
some things remain constant, and in the case of the
AVR 645 that is a requirement for audio power best
served by our time-honored high-current, ultrawide
bandwidth amplifier design. The AVR 645’s seven-
channel amplifier provides the power to reproduce the
loudest crescendos or cinema sound effects while
remaining virtually free from distortion or system noise.
With a combination of state-of-the-art circuitry, digital
technology and proven performance with an elegant
design that is compatible with the latest source com
-
ponents and video displays
, the AVR 645 represents
the culmination of Harman Kardon’s fifty-plus year
history of delivering the finest sonic performance.
