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

amplifier

cannot

provide

these

higher

currents.

For

this

reason,

the

PM665

was

designed

to

provide

60

amperes

of

instantaneous

current.

WW

Ultrawide

Bandwidth

The

bandwidth

of

this

unit

is

exceptionally

wide

and

inde-

pendent

of

negative

feedback.

This

improves

transient

accuracy

and

phase

linearity.

MiLow

Negative

Feedback

This

unit

has

been

designed

to

have

low

distortion

and

wide

bandwidth

without

high

negative

feedback.

This

further

improves

its

dynamic

accuracy.

Dual

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.

@

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.

HM

Moving

Coil

Cartridge

Amplifier

A

high

sensitivity,

low

noise

amplifier

is

provided.

This

permits

the

direct

input

of

most

moving

coil

cartridges.

Mi

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.

@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.

M@Bass

Contour

Bass

contour

is

an

exclusive

Harman

Kardon

feature

which

provides

two

major

benefits:

it

can

equalize

and

restore

the

low

frequency

response

of

small

loud-speakers.

and

it

can

be

used

in

place

of

conventional

loudness

contour.

But

untike

conventional

bass

boost

circuits,

Harman

Kardon’s

bass

contour

also

includes

a

phase

correction

circuit

that

maintains

clear,

natural

sound.

must

be

added.

Often,

this

amount

is

less

than

that

allows

you

to

add

100pF,
