M@

HCC

(High-instantaneous

Current

Capabil-

ity)

Recent

studies

have

shown

that

while

reproducing

dynamic

music

signals

the

instantaneous

impedances

of

nearly

ail

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

HK6750

and

HK6250

were

designed

to

provide

respectively

22

and

30

amperes

of

instantaneous

current.

B

Ultrawide

Bandwidth

The

bandwidth

of

this

unit

is

exceptionally

wide

and

inde-

pendent

of

negative

feedback.

This

improves

transient

accu-

racy

and

phase

linearity.

B

Low

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.

@

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.

FEATURES

GENERAL

INSTRUCTIONS

Always

Use

Correct

AC

Voltage

Always

connect

the

power

cord

to

a

domestic

mains

outlet.

Never

connect

the

unit

to

an

outlet

supplying

a

higher

voltage.

This

may

create

a

fire

hazard.

This

unit

is

supplied

with

a

voltage

selector

enabling

selection

between

230V

and

240V

on

the

rear

panel.

If

the

selector

is

not

set

to

the

local

voltage,

set

the

selector

to

the

correct

voltage

with

a

screwdriver

before

connecting

the

power

cord

to

a

mains

outlet.

Handle

the

Power

Cord

Gently

@

Do

not

disconnect

the

plug

from

the

AC

outlet

by

pulling

the

cord;

always

pull

the

plugitself.

Pulling

the

cord

may

break

the

wire.

@

If

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:

e

Moist

or

humid

places.

e

Places

exposed

to

direct

sunlight

or

close

to

heating

equipment.

e

Extremely

cold

locations

such

as

those

in

the

direct

draft

from

an

air

conditioner.

e

Places

subject

to

excessive

vibration

or

dust.

e

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.

not

guarantee

against

result-

ing

from

any

modification.

\f

water,

a

hairpin

or

wire

accidentally

enters

the

unit,

imme-

diately

unplug

the

power

cord

from

the

outlet

to

prevent

shock

and

consult

an

authorized

Harman

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
