Harman Kardon HK620 - Connections; Connecting Other Components; Wired Remote Control; Connecting Speakers

Connecting Other
Components
1. Make sure your amplifier and other
components are turned off.
2. Connect each component's Output
jacks to the corresponding Input jacks
on the back of your amplifier. Use the
white, black or gray plugs to connect
Left channel jacks; use the red plugs
for Right jacks.
3. To use a 3-head tape deck that allows
monitoring of the actual recording
while it is in process, connect it to
TAPE 2 jacks.
For Customers with a Turntable:
To connect a turntable, an optional
Phono board must be installed. This
board can be set to MM or MC. With the
Phono board installed, however, you
cannot use the AUX input. If you want to
have the Phono board installed, consult
your authorized Harman Kardon service
center.
CONNECTIONS
Wired Remote Control
To contro! 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 components may not be compatible,
but it will not hurt to experiment.
A second wire may be used to connect
your amplifiers 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 Length Gauge
Up to2.5 meter 18 AWG
Upto4meter 16AWG
Upto6meter 14AWG
Over 6 meter 10-12 AWG custom
speaker cable
2. Avoid coiling excess wire with or near
line level hook-up cords.
IMPORTANT: When connecting two
pairs of speakers, determine the
impedance of each pair by looking on
the back of the speakers, or in your
owner's manual, or by contacting your
dealer or manufacturer. Then refer to the
following chart to see if both sets may be
played simultaneously.
Ifimpedance Can both pairs
of the two be played
pairs is: simultaneously?
80/8Q YES
8Q/EQ NO
8Q/40. NO
6Q/6Q NO
6Q/4Q NO
4Q/4Q NO
WARNING: Do not play both sets of
speakers simultaneously except as
recommended above. Amplifier may
overheat.
AC Power
Plug the cord into a polarized wall
socket.
NOTE: The power does not shut off
completely by just turning the power off.
So power cord should be removed from
AC outlet when not in use for a
prolonged time.
AC Convenience Receptacles
(120 Volt units only)
Other stereo components may be
plugged into the back of your amplifier.
1. If a component is plugged into the
SWITCHED receptacle, power will be
supplied to that component only when
your amplifier is turned on.
2. If a component is plugged into the
UNSWITCHED receptacle, power will
be supplied whether your amplifier is
on or off.
NOTE: Do not connect any component
that requires more than 180 watts of
power. Check the owner’s manual or the
back of the component to find its power
requirement.
