INTRODUCTION

You

are

now

the

owner

of

one

of

the

most

advanced

and

versatile

profes-

sional

stereo

cassette

tape

decks

ever

designed

for

home

use.

The

HK

1000

with

the

Dolby

Noise

Reduction

System*

has

been

engineered

expressly

for

the

recording

enthusiast

with

professional

features

and

perform-

ance

that

are

on

a

par

with,

or

exceed,

the

most

versatile

reel

to

reel

recorders.

Perhaps

no

other

electronic

concept

in

recent

years

has

caused

so

much

talk,

or

has

been

so

well

received

as

the

Dolby

noise

reduction

system.

The

Dolby

system

has

been

commercially

available

for

a

number

of

years

and

it

is

presently

being

used

by

every

major

recording

company

in

the

world.

This

system

has

permitted

recording

engineers

to

broaden

the

limits

of

signal-to-noise

range

in

tape

by

another

10

to

15

decibels.

Up

to

now

it

has

been

difficult

to

achieve

noise

-free

recordings

and

play-

back

from

a

tape

cassette

because

of

special

inherent

problems.

During

the

past

year,

several

new

low

-noise

cassettes

have

appeared

which

have

helped

achieve

better

noise

figures,

but

even

with

these

new

uniform

oxide

and

higher

saturation

tapes,

noise

still

persists

as

a

problem.

This

is

why

the

Dolby

noise

reduction

system

is

such

a

remarkable

achieve-

ment

and

a

definite

asset

to

recording

enthusiasts.

It

permits

a

greater

dynamic

range

giving

the

sound

greater

impact

and

clarity.

Dolby's

system

is

essentially

a

compression

-expansion

configuration,

which

compresses

the

signal

during

its

initial

phase

and

expands

it

to

match

the

initial

compression

during

the

second

phase,

but

it

accomplishes

all

this

without

any

apparent

effect

on

the

signal.

*The

word

"Dolby"

is

a

trademark

of

Dolby

Laboratories,

Inc.

The

Dolby

B

system

employed

in

our

Harman/Kardon

HK

1000

operates

on

both

record

and

playback.

It

boosts

low-level,

high

frequency

signals

prior

to

recording,

then

attenuates

these

same

signals

in

a

precisely

equalized

mirror

image

during

playback.

When

this

is

accomplished,

all

of

the

additional

noise

that

may

have

been

added

by

the

cassette

recorder

is

eliminated

or

reduced

to

an

inaudible

level.

The

HK

1000

enables

the

recording

enthusiast

to

make

cassette

recordings

with

a

tremendous

gain

in

signal-to-noise

ratio

. .

as

much

as

10

db!

It

also

gives

him

the

ability

to

dub

tapes

over

and

over

again

with

no

increase

in

noise.

It

takes

only

a

few

minutes

of

listening

to

a

Dolby

processed

tape

on

the

HK

1000

to

sense

the

incredible

clarity

and

naturalness

of

sound.

It

is

not

simply

the

absence

of

tape

hiss

during

the

quieter

passages,

but

the

absence

of

all

types

of

effects,

inaudible

or

unidentifiable

in

themselves,

that

contribute

to

this

cleaner

sound.

The

versatility

of

the

HK

1000

makes

it

completely

compatible

for

use

with

Dolby

or

non

-Dolby

tapes.

You

may

record

tapes

without

the

Dolby

system

for

use

with

standard

cassette

recorders

or

you

may

playback

tapes

made

on

a

standard

cassette

recorder.

We

know

you

are

eager

to

install

and

use

your

tape

recorder

but

we

sin-

cerely

urge

you

to

read

this

instruction

book.

The

few

minutes

that

it

will

take

to

familiarize

yourself

with

the

proper

techniques

for

using

this

fine

tape

recorder

will

prove

rewarding

and

will

ensure

many

years

of

uninterrupted

enjoyment

with

it.
