FEATURES
@ HCC (High-instantaneous Current Capability)
Recent studies have shown that while reproducing dynamic
music signals the instantaneous impedances of nearly all
loud-speakers drop to less than one third of the nominal
ratings. These low instantaneous impedances typically re-
quire 3 to 6 times more current than an 8 Ohm resistive load.
Reduced dynamic range and increased distortion will result
if the amplifier cannot provide these higher currents. For
this reason, the hk795i was designed to provide 50 amperes
of instantaneous current.
& Ultrawide Bandwidth
The bandwidth of this unit is exceptionally wide and inde-
pendent of negative feedback. This improves transient ac-
curacy and phase linearity.
= Low Negative Feedback
This unit has been designed to have low distortion and wide
bandwidth without high negative feedback. This further
improves its dynamic accuracy.
@ Discrete Component Circuitry
In order to achieve the above goals, all discrete electronic
circuitry has been employed. All available integrated circuits
could not provide this high level of performance.
@ Active/Passive Phono Section
Unique circuitry provides precise passive RIAA equalization
(without negative feedback). Then the same low level of
negative feedback is applied at all frequencies from
20Hz—20kHz, resulting in improved transient accuracy.
a Sophisticated Electronic Protection
Harman Kardon engineers developed a unique protection
system that permits high instantaneous current to be driven
into speaker systems but protects the amplifier from short-
circuited or damaged speakers and wires. This protection
system in no way limits amplifier output voltage or current
during music reproduction, and therefore has no negative
effect on sound quality.
m@ Digital Synthesized Quartz-locked Tuning
Quartz-locked tuning accuracy eliminates drifting and mis-
tuning, thereby guarantying optimum sound quality. Eight
AM and eight FM stations can be simultaneously stored in
the memory. They will remain for one week even if there
is a loss of power.
B Constructed for Audio Purity
The internal wiring, layout and materials have been chosen
to minimize noise, hum and interaction of the various cir-
cuits.
@ Bass and Treble Turnover Selectors
This feature alters the range of adjustment provided by the
bass and treble controls. The user can more precisely contour
the tone controls to match the speaker systems and room
acoustics.
Always Use at 120V AC
This unit is designed for operation with 120V AC. Connect
only to domestic AC outlets. Never connect the unit to an
outlet supplying a higher voltage. This may create a fire
hazard. ,
Handle the Power Cord Gently
@ Do not disconnect the plug from the AC outlet by pulling
the cord; always pull the plug itself. Pulling the cord may
break the wire.
@ If you do not intend to use your unit for any considerable
length of time, disconnect the plug from the AC outlet.
@ Do not place furniture or other heavy objects on the cord,
and avoid dropping heavy objects.on it. Also do not make
a knot in the power cord. Not only may the cord be damaged,
it can also cause a short circuit and a consequent fire hazard.
Place of Installation
Place your unit on a firm and level surface. Avoid installing
-your unit under the following conditions:
> Moist or humid places.
> Places exposed to direct sunlight or close to heating
equipment. :
> Extremely cold locations such as ‘those in the direct draft
from an air conditioner.
> Places subject to excessive vibration or dust.
> Poorly ventilated places.
Do not cover the ventilation slots:on the top of the unit.
This will cause the temperature inside the unit to rise, which
can eventually effect the reliability of your unit.
Moving the Unit
Before moving the unit, be sure to unplug the power cord
from the AC outlet and disconnect the interconnection cords
to other units.
Do Not Open the Cabinet
To prevent fire or shock hazard, do not tamper with internal
components for inspection or maintenance. Harman Kardon
does not guarantee against performance degradation re-
sulting from any modification. --
If water, a hairpin or wire accidentally enters the unit, im-
mediately unplug the power cord from the AC outlet to
prevent shock and consult an authorized Harman Kardon
service station. If you use the unit under this condition, it
may cause a fire or shock hazard.
Cleaning
When the unit gets dirty, wipe. it with a soft dry cloth. If
necessary, wipe it with a soft cloth dampened with mild soapy
water and then wipe with a dry cloth.
Never use benzine, thinner, alcohol or other volatile agent,
and avoid spraying an insecticide near the unit.

FM Antenna
If
experiencing
poor
FM
reception
while
using
the
accessory
antenna,
the
use
of
an
outdoor
antenna
exclusively
for
FM
reception
is likely
to
improve
FM
reception.
The
connecting
wire
between
the
antenna
and
the
antenna
input
terminal
is
called
a
feeder.
Most
feeders
are
300
Ohm
parallel
or
75
Ohm
coaxial
cables.
We
recommend
type
3C-2V
or
5C-2V
75
Ohm
coaxial
cable
to
be
used
with
this
unit
to
enable
it
to
perform
to
its
fullest
capacity.
The
coaxial
cable
has
a
stronger
resistance
against
loss
and
interference
compared
to
a
parallel
feeder.
If there is a lot of noise while receiving an FM broadcast,
we recommend that you make a ground connection. Connect
one end of a thick wire to the antenna “GND” terminal and
wind the other end around an earth bar or earth plate and
drive it into the ground.

CAUTION:
Never
make
a
connection
to
a
gas
pipe
because
it.can
cause
fire
hazard.
AM Antenna
The
AM
loop
antenna
attached
to
this
unit
allows
sufficient
reception,
except
in
an
area
where
AM
signals
are
weak.
In
a
fringe
area
or
inside
a
concrete
building
where
the
re-
ception
is
weak
and
the
sound
quality
is
poor,
an
outdoor
AM
antenna
is
likely
to
improve
reception.
Place the AM loop antenna as far away from
this unit as possible, e.g. hang it on wall,
without touching a metal object. You may
also install the AM loop antenna by fitting
it onto the antenna holder on the rear panel.
To remove the AM loop antenna from the
unit, simply pull it out of the holder.
AM Outdoor

Connecting Other Components
Carefully connect the plugs to the left and right channel
jacks. Push the plugs in all the way. Poor setting of the plugs
tends
to
cause
hum
or
intermittent
sound
and
may
damage
the speakers.
NOTE: While you are connecting this unit to the rest of
your high fidelity system, please unplug the power cord,
disconnecting not only this unit but all the components, from
the AC outlet.
Do not interwind the connection wires with the power cord.
If interwound, the sound quality may be degraded.
AC Convenience Receptacles
This unit is provided with three AC convenience receptacles
on the rear panel for supplying power to a turntable, tape
deck or other low power component. The “SWITCHED”
receptacles have a combined power capacity of 180 watts.
The “UNSWITCHED” receptacle has a power capacity of
180 watts. Check the component’s owner’s manual to find
its power requirement.
SWITCHED: The power to this receptacle is turned on and
off by this unit’s power switch.
UNSWITCHED: The power to this receptacle is independent
of this unit’s power switch.
Connecting Speakers
Connect the speaker wires carefully to the speaker terminals
on the rear panel so as not to mistake the left and the right
channels or reverse the speaker polarities (+ and —).
Use sufficiently thick wire (18 gauge for short lengths,
16-12 gauge for longer lengths). It is recommended to
use color-coded wire for easy polarity identification. Speaker
wires should be as short as possible, and the left and the
right channel wires should be the same length.
1. Remove about 3/4 inch
(20mm) of insulation from
the end of each wire and
twist the strands of each
end.
2. After making sure of the
correct channel and
polarity, loosen the
“SPEAKER SYSTEM”
terminal knob and insert
the conductor directly into
the recess at the upper-
right of the terminal. Then
tighten the terminal knob,
and the end of speaker Me Ge 3
wire is automatically wound around the terminal.
CAUTION: Two speaker systems can be connected to this
unit. The minimum speaker impedance should be 8 Ohm
when only one speaker system is connected. When two
speaker systems are connected, care should be taken that
net impedance does not become less than 8 Ohm.
