HK6800 and HK6900 Connections If you are using a single set of 8-ohm speakers, set the SPEAKER OPERATING MODE switch to the 8S2 position. In all other cases, use the 4f1 position. If you are in doubt about the impedance of your speakers, use the 4-ohm position, since the power amplifier runs cooler in this mode. Having this switch set to 8C2, if you are using 4-ohm or 6-ohm speakers may result in overheating of the amplifier or failure of an internal fuse. If you are using two pairs of speakers, it is important to note that the combined total impedance of both sets of speakers must not be less than 4 ohms. If the combined impedance is lower, you may overload the amplifier, resulting in overheating or failure of an internal fuse. Two sets of 8-ohm speakers presents a combined total impedance of 4 ohms, which is an acceptable load for your amplifier as long as you set the SPEAKER OPERATING MODE switch to 4 ohms. If you have questions, consult your Harman Kardon dealer before adding a second set of speakers to your system. Connecting a turntable Your HK6800 or HK6900 has two sets of PHONO input jacks for connecting turntables. One set of jacks is marked MC, for Moving Coil. If you have a moving coil cartridge that generates at least 120µV mounted on your turntable, be sure you connect the turntable to the MC jacks. These jacks are internally wired to a special step-up amplifier stage. GNP LEF-1 AC NAY' The other set of jacks is marked MM, for Moving Magnet. If you have a regular moving magnet cartridge mounted on your turntable, connect the turntable only to the MM inputs, as the sizeable volume boost of the MC jacks will cause volume problems and severe distortion. Make sure you connect the thin ground wire from your tuntable to the GND post located next to the phono input jacks. Failure to connect this ground wire can result in a distracting hum when you play your turntable. When only one turntable is used, be sure to insert the attached shorting pin plug into the PHONO MM or MC jacks that are not being used. Connecting a CD player Attach the patch cord from the CD input jacks to your compact disc player. Connecting a tuner Attach the patch cord from the TUNER input jacks to your tuner. Be sure you connect an antenna to your tuner; otherwise, the quality of your AM and FM signal may be poor. Connecting a tape deck You can have several tape decks connected to your HK6800 or HK6900. The best choice is to connect your tape deck(s) to the jacks labeled VCR/TAPE 1 or VCR/TAPE 2. The IN and OUT connectors on your tape deck correspond to the opposite connectors on the back of your amplifier. That is, you connect OUT on the tape deck to IN on the amplifier. A third tape deck can be connected to the AUX or A/V audio connectors if the deck will be used only for playback. Connect a patch cord from the audio OUT connectors on the tape deck to either the AUX or the A/V audio in connectors on your HK6800 or HK6900. Note that the VCR/TAPE input jacks can be used for connecting either a tape deck or a VCR or other video source. Video equipment connection is described in the following sections. Connecting a VCR There are two ways you can connect a VCR to your system. One way is to use the A/V connectors; the other is to use the VCR/TAPE 1 and 2 connectors. A/V: If you connect your VCR to the A/V inputs, you will be able to playback videocassettes, but not record on them. Connect a patch cord from the audio out connectors on your VCR to the A/V audio connectors. Then connect a patch cord from the video out connector on your VCR to the A/V video connector. VCR/TAPE 1 and VCR/TAPE 2: If you connect your VCR to the VCR/TAPE 1 or 2 inputs, you will be able to both playback and record videocassettes. Connect a patch cord from the audio OUT connectors on your VCR to the VCR/TAPE 1 (or 2) audio IN connectors. Connect audio IN on your VCR to the VCR/TAPE 1 (or 2) audio OUT connectors. Then connect a patch cord from the video OUT connector on your VCR to the VCR 1 (or 2) video IN connector. Connect video IN on your VCR to the VCR 1 (or 2) video OUT connector. Be sure you plug the video connector into the jacks that correspond with the audio connectors (e.g., if you've plugged the audio into VCR/ TAPE 2, plug the video into VCR 2). You can watch the picture from a VCR on your television while listening to the sound through your hi-fi system. If your source is high-quality (such as Hi-Fi VCR output), and you can position your television set between your speakers, the enhanced sound field will contribute greatly to your video enjoyment. Connecting a video laser disc player Connect a patch cord from the audio out connectors on your video disc player to the A/V audio connectors. Then connect a patch cord from the video out connector on your video laser disc player to the A/V video connector. Connecting a video monitor Connect a patch cord from the MONITOR OUT video connector to the video IN connector on your TV monitor/ receiver. The video signal that goes to your monitor will come from the A/V component you have selected using the FUNCTION selector, or from the VCR selected using the VCR/TAPE MONITOR selector. Connecting other video equipment You can also use the A/V audio connectors to connect the audio (stereo or mono) output of a television tuner or MIS adaptor into your hi-fi system. Connecting an external power amplifier If you want to use your HK6800 or HK6900 simply as a preamplifier and connect it to an external power amplifier, use the PRE-OUT connectors in the upper-left corner. Connect the patch cord from the PRE-OUT jacks on the HK6800 or HK6900 to the jacks on your external power amplifier. Then connect your speakers to your external power amplifier. 7

Connections
If
you
are
using
a
single
set
of
8
-ohm
speakers,
set
the
SPEAKER
OPERATING
MODE
switch
to
the
8S2
position.
In
all
other
cases,
use
the
4f1
position.
If
you
are
in
doubt
about
the
impedance
of
your
speakers,
use
the
4
-ohm
position,
since
the
power
amplifier
runs
cooler
in
this
mode.
Having
this
switch
set
to
8C2,
if
you
are
using
4
-ohm
or
6
-ohm
speakers
may
result
in
overheating
of
the
amplifier
or
failure
of
an
internal
fuse.
If
you
are
using
two
pairs
of
speakers,
it
is
important
to
note
that
the
combined
total
impedance
of
both
sets
of
speakers
must
not
be
less
than
4
ohms.
If
the
combined
impedance
is
lower,
you
may
overload
the
amplifier,
resulting
in
overheating
or
failure
of
an
internal
fuse.
Two
sets
of
8
-ohm
speakers
presents
a
combined
total
impedance
of
4
ohms,
which
is
an
acceptable
load
for
your
amplifier
as
long
as
you
set
the
SPEAKER
OPERATING
MODE
switch
to
4
ohms.
If
you
have
questions,
consult
your
Harman
Kardon
dealer
before
adding
a
second
set
of
speakers
to
your
system.
Connecting
a
turntable
Your
HK6800
or
HK6900
has
two
sets
of
PHONO
input
jacks
for
connecting
turntables.
One
set
of
jacks
is
marked
MC,
for
Moving
Coil.
If
you
have
a
moving
coil
cartridge
that generates
at
least
120μV
mounted
on
your
turntable,
be
sure
you
connect
the
turntable
to
the
MC
jacks.
These
jacks
are
internally
wired
to
a
special
step-up
amplifier
stage.

The
other
set
of
jacks
is
marked
MM,
for
Moving
Magnet.
If
you
have
a
regular
moving
magnet
cartridge
mounted
on
your
turntable,
connect
the
turntable
only
to
the
MM
inputs,
as
the
sizeable
volume
boost
of
the
MC
jacks
will
cause
volume
problems and
severe
distortion.
Make
sure
you
connect
the
thin
ground
wire
from
your
tuntable
to
the
GND
post
located
next
to
the
phono

jacks.
Failure
to
connect
this
ground
wire
can
result
in
a
distracting
hum
when
you
play
your
turntable.
When
only
one
turntable
is
used,
be
sure
to
insert
the
attached
shorting
pin
