Harman Kardon HK6900 - Operation Guide; Recording and Copying Procedures

HK6800 and HK6900 Connections _
If you are using a single set of 8-ohm speakers, set the
SPEAKER OPERATING MODE switch to the 30 position.
In all other cases, use the 40 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 80 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 120uV 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 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.
Conne<ting 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.
Conne<ting 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
MTS 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.
