MHCC
(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
require
3
to
6
times
more
current
than
an
8
Ohm
resistive
load.
Reduced
dynamic
range
and
increased
distortion
will
result
if
the
am-
plifier
cannot
provide
these
higher
currents.
For
this
reason,
the
PM655
Vxi
was
designed
to
provide
45
amperes
of
in-
stantaneous
current.
gm
Ultrawide
Bandwidth
The
bandwidth
of
this
unit
is
exceptionally
wide
and
inde-
pendent
of
negative
feedback.
This
improves
transient
accuracy
and
phase
linearity.
wLow
Negative
Feedback
This
unit
has
been
designed
to
have
low
distortion
and
wide
bandwidth
without
high
negative
feedback.
This
further
im-
proves
its
dynamic
accuracy.
mDual
RIAA
Phono
Equalization
The
phono
section
employs
Harman
Kardon’s
unique
dual
RIAA
equalization
circuitry.
RIAA
equalization
is
used
in
both
the
open-loop
and
closed-loop
signal
path
(with
and
without
negative
feedback).
This
permits
the
application
of
constant
low-level
negative
feedback
throughout
the
audio
range.
w
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.
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.
mw
Moving
Coil
Cartridge
Amplifier
A
high
sensitivity,
low
noise
amplifier
is
provided.
This
permits
the
direct
input
of
most
moving
coil
cartridges.
m@
Capacitance
Trim
Selector
This
feature
enables
precise
impedance
matching
between
moving
magnet
type
cartridges
and
the
phono
circuitry.
The
widest,
flattest
frequency
response
possible
can
be
obtained
from
any
high
quality
phono
cartridge.
m@Pre-out/Main-in
Switch
This
feature
allows
independent
use
of
the
preamplifier
and
main
(power)
amplifier
sections.
With
this
switch
in
the
“integrated”
position,
the
preamplifier
section
is
internally
connected
to
the
main
(power)
amplifier.
By
depressing
this
switch
to
the
“separate”
position,
the
preamplifier
output
and
main
(power)amplifier
input
jacks
on
the
rear
panel
become
active.
mPhase-correct
Loudness
Phase-correct
loudness
is
an
exclusive
Harman
Kardon
feature
which
provides
two
major
benefits:
it
can
equalize
and
restore
the
low
frequency
response
of
small
joud-speakers,
and
it
can
be
used
in
place
of
conventional
loudness
contour.
But
unlike
conventional
bass
boost
circuits,
Harman
Kardon’s
phase-correct
loudness
also
includes
a
phase
correction
circuit
that
maintains
clear,
natural
sound.
FEATURES
GENERAL
INSTRUCTIONS
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.
lf
your
unit
will
be
left
unused
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.
b>
Extremely
cold
locations
such
as
those
in
the
direct
draft
from
an
air
conditioner.
»
Piaces
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
affect
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
resulting
from
any
modification.
If
water,
a
hairpin
or
wire
accidentally
enters
the
unit,
imme-
diately
unplug
the
power
cord
from
the
AC
outlet
to
prevent
shock
and
consult
an
authorized
Harman
Kardon
service
sta-
tion.
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
ne-
cessary,
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
agents,
and
avoid
spraying
an
insecticide
near
the
unit.
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,
discon-
necting
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.
When
only
one
turntable
is
used,
be
sure
to
insert
the
attached
short-pin
plug
into
the
PHONO
MM
or
MC
jacks
that
are
not
being
used.
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
(20
mm)
of
insulation
from
the
end
of
each
wire
and
twist
the
strands
of
each
end.

terminal
knob
and
insert
the
con-
ductor
directly
into
the

at
the
upper-left
of
the

minal.
Then
tighten
the
terminal
knob,
and
the

is
automatically
wound
around
the
terminal.
3.
Set
the
SPEAKER
OPERATING
MODE
switch
on
the
rear
panel
to
match
the
impedance
of
your
speakers.
If
your
speakers
are
nominally
4
Ohms,
set
this
switch
to
the
“4Q"
position.
If
your
speakers
are
nominally
8
Ohms,
set
this
switch
to
the
“8Q”
position.
The
HIGH
VOLTAGE
in-
dicator
on
the
front
panel
will
then
illuminate.
CAUTION:
Two
speaker
systems
can
be
connected
to
this
unit.
When
two
speaker
systems
are
connected,
care
should
be
taken
that
net
impedance
does
not
become
fess
than
8
or
4
Ohms
depending
on
the
position
of
the

can
be
connected
to
the
PM655
Vxi
am-
plifier.
To
connect
a
source
such
as
a
VCR,
for
example,
leads
must
be
connected
for
both
AUDIO
and
VIDEO
input
and
output,
so
a
total
of
6
leads
are
necessary.
Connect
the

jacks
of
the
VCR
to
the
VCR/TAPE
1

in
the
same
way.
NOTE:
When
you
connect
the
leads,
make
sure
that
the
