CONNECTIONS
Connections
Connecting Other Components
1. Make sure your amplifier and other compo-
nents are turned off.
2. Connect each component's Output/Play jacks
to the corresponding Input jacks on the back
of your amplifier and, if available, the compo-
nent’s Input/Record jacks to the Output jacks
of the HK 970. Use the white, black or gray
plugs to connect Left channel jacks; use the
red plugs for Right channel jacks.
3. A record player with MM cartridge must be
connected to the Phono Input jacks and a
separate ground wire to the ground terminal
screw above.
Wired Remote Control
To control your amplifier with an external
infrared remote sensor, connect the wire from
the remote sensor to the REMOTE IN jack on the
back panel. Or, if another stereo component has
a built-in infrared remote sensor and a Remote
Output jack, it may be possible to connect this
jack to the REMOTE IN jack of your amplifier. All
Harman Kardon products with »Remote In« and
»Remote Out« jacks are compatible with one
another, except for the Citation 22, 24 and 25.
Other manufacturers' remote sensors and com-
ponents may not be compatible, but it will not
hurt to experiment. A second wire may be used
to connect your amplifier's REMOTE OUT jack to
the Remote Input of another stereo component.
Continue this process to include additional
components (if compatible).
Connecting Speakers
1. For best performance, use high quality
speaker cables. However, ordinary copper wire
can be used if the gauge meets the following
requirements:
Wire Min.
Length
Diameter
Up to 2.5 meter
1 mm
Up to 4 meter
1.25 mm
Up to 6 meter
1.6 mm
Above 6 meter
2-2.5 mm
2. Avoid rolling excess wire with or near signal
interconnects.
External Power Amplifiers
For applications where higher power is desired,
connect the Pre-Out Jacks to the Main In Jacks
of an external power amplifier. The level of the
output can be adjusted between -3 and +3 dB
with an internal button. To adjust the level, gen-
tly insert a small screwdriver into the button and
turn clockwise to increase or counter-clockwise
to decrease the output level.
IMPORTANT:
When connecting two pairs of
speakers, determine the impedance of each pair
by looking on the back of the speakers, in your
owner's manual, or by contacting your dealer or
manufacturer.
You can listen to two pairs of speakers at
the same time ONLY if the impedance of
EACH speaker is NOT LESS THAN 8 Ohms.
WARNING:
Do not play sets of speakers
simultaneously except as recommended above.
Amplifier may overheat.
AC Power
Plug the cord into a 230 VAC wall socket.
Power indicator will light up to indicate power
ON. To completely disconnect the power input,
the main plug must be disconnected from the
mains.
