INTRODUCTION You are now the owner of an instrument unique in concept and design. The Harman/Kardon Model 900+ multichannel receiver encompasses the best of all forms of musk reproduction. It may be installed as a stereophonic receiver capable of delivering clean, articulate sound at moderate power levels, or as a quadriphonic receiver that can fill your listening room with spacious, three dimensional sound. When you listen to your new Harman/Kardon multichannel receiver you will instantly recognize that something truly phenomenal is taking place. The sound, which normally emerges from the speaker boxes, will lose its boundaries and will emanate from all over the room recreating the scope, depth and breadth of the concert hall. The walls of your listening room will seem to disappear and you will find yourself surrounded by a sound field that has the same ambience and spaciousness which marks a live performance. Stereophonic balance and perspective will be retained, but now there will be the addition of depth which will project you into the middle of the hall. Applause, for example, will emerge from the front, sides and rear. And during playback of a live concert don't be too startled if you hear someone coughing or rustling his program from behind you. The 4-channel medium is even more dramatic for contemporary music, especially if the music was originally written for four channel reproduction. Sounds bounce back and forth from the corners of the room involving you completely with the performance. It's a new and exhilarating kind' of sound that will make listening to music a new experience. The 900+ bears the heritage of the Harman/Kardon trademark - ultrawideband frequency response, virtually immeasurable distortion and all of the required conveniences so essential for the ultimate enjoyment of high fidelity reproduction. We urge you to read this manual carefully prior to installing and operating your receiver. The 900+ is not a complicated instrument. However, there are certain aspects of its operation which should be understood clearly before you install and operate it. Happy listening! WARRANTY and SERVICE POLICY POLICY We warrant this receiver to be free from defects in material and workmanship under normal use and service, and in accordance with the conditions set forth below. Should a defect occur within the period specified, and provided that the unit is returned to either HARMAN/KARDON or an authorized HARMAN/KARDON warranty station, transportation prepaid, and which our examination shall disclose to our satisfaction to be defective, we will, for a period of two (2) years from date of purchase, either replace or repair and install any defective parts of the receiver free of charge. EXCEPTIONS This warranty does not include any obligation as to: a) repair or replacement of the wooden enclosure due to damage incurred after initial delivery, b) transportation charges to and from the factory or an authorized warranty station. REGISTRATION To obtain service under the terms of this policy, it is necessary for you to retain your ORIGINAL BILL of SALE. The enclosed registration card will NOT be considered proof of purchase. In the event your equipment requires service during the warranty period, only presentation of your original bill of sale to either a factory-authorized repair agency or the factory itself will insure your rights under the policy as outlined in this manual.

INTRODUCTION
You
are
now
the
owner
of
an
instrument
unique
in
concept
and
design.
The
Harman/Kardon
Model
900+
multichannel
receiver
encompasses
the
best
of
all
forms
of
musk
reproduction.
It
may
be
installed
as
a
stereophonic
re-
ceiver
capable
of
delivering
clean,
articulate
sound
at
moderate
power
levels,
or
as
a
quadriphonic
receiver
that
can
fill
your
listening
room
with
spacious,
three
dimensional
sound.
When
you
listen
to
your
new
Harman/Kardon
multichannel
receiver
you
will
instantly
recognize
that
something
truly
phenomenal
is
taking
place.
The
sound,
which
normally
emerges
from
the
speaker
boxes,
will
lose
its
boundaries
and
will
emanate
from
all
over
the
room
recreating
the
scope,
depth
and
breadth
of
the
concert
hall.
The
walls
of
your
listening
room
will
seem
to
dis-
appear
and
you
will
find
yourself
surrounded
by
a
sound
field
that
has
the
same
ambience
and
spaciousness
which
marks
a
live
performance.
Stereo-
phonic
balance
and
perspective
will
be
retained,
but
now
there
will
be
the
addition
of
depth
which
will
project
you
into
the
middle
of
the
hall.
Applause,
for
example,
will
emerge
from
the
front,
sides
and
rear.
And
during
playback
of
a
live
concert
don't
be
too
startled
if
you
hear
someone
coughing
or
rustling
his
program
from
behind
you.
The
4
-channel
medium
is
even
more
dramatic
for
contemporary
music,
espe-
cially
if
the
music
was
originally
written
for
four
channel
reproduction.
Sounds
bounce
back
and
forth
from
the
corners
of
the
room
involving
you
completely
with
the
performance.
It's
a
new
and
exhilarating
kind'
of
sound
that
will
make
listening
to
music
a
new
experience.
The
900+
bears
the
heritage
of
the
Harman/Kardon
trademark
ultra-
wideband
frequency
response,
virtually
immeasurable
distortion
and
all
of
the
required
conveniences
so
essential
for
the
ultimate
enjoyment
of
high
fidelity
reproduction.
We
urge
you
to
read
this
manual
carefully
prior
to
installing
and
operat-
ing
your
receiver.
The
900+
is
not
a
complicated
instrument.
However,
there
are
certain
aspects
of
its
operation
which
should
be
understood
clearly
before
you
install
and
operate
it.
Happy
listening!
