and

HK6900

Connections

Before

you

begin

to

connect

this

unit

to

your

system,

be

sure

that

all

components

are

turned

off

and

unplugged

from

the

electrical

outlet.

As

you

connect

each

component,

carefully

connect

the

plugs

to

the

input

jacks,

being

sure

to

push

the

plugs

in

all

the

way.

Loose

connection

of

a

plug

can

cause

hum

or

other

intermittent

noise.

Take

care

to

match

left

and

right

component

plugs

with

the

left

and

right

input

jacks

on

the

back

of

the

amplifier.

Common

practice

is

to

use

the

red

plug

as

right,

and

the

white,

gray,

or

black

plug

as

left.

Do

not

wind

the

component

cables

with

the

power

cord;

doing

so

may

degrade

the

sound

quality

Power

outlets

To

the

right

of

the

back

panel

on

North

American

and

Japanese

versions

are

located

three

AC

power

outlets.

The

two

outlets

labeled

SWITCHED

are

controlled

by

the

power

switch

on

the

front

of

the

amplifier.

When

the

power

is

switched

off

at

the

front

panel

button,

power

is

also

turned

off

to

the

SWITCHED

outlets.

You

can

plug

the

power

cord

of

a

tuner,

tape

deck,

turntable,

or

other

low

-power

component

into

these

outlets.

When

you

turn

off

your

amplifier,

units

plugged

into

the

SWITCHED

outlets

will

be

turned

off

simultaneously.

The

SWITCHED

outlets

have

a

combined

power

rating

of

200

watts.

Make

sure

that

the

units

that

you

plug

into

these

outlets

do

not

draw

more

than

200

watts

total.

Check

the

owner's

manuals

to

determine

how

much

power

each

unit

draws.

The

UNSWITCHED

outlet

is

not

controlled

by

the

power

switch.

This

outlet

receives

power

as

long

as

the

HK6800

or

HK6900

is

plugged

into

an

AC

outlet.

A

unit

plugged

into

the

UNSWITCHED

outlet

can

remain

turned

on

even

if

your

amplifier

is

turned

off.

This

outlet

has

a

power

rating

of

200

watts.

Make

sure

that

the

unit

you

plug

into

this

outlet

does

not

draw

more

than

200

watts.

Connecting

speakers

Speaker

wires:

For

the

best

sound

quality,

you

may

choose

to

use

the

highest

quality

speaker

cables

you

can

afford.

However,

common

"zip

cord"

from

a

hardware

store

can

be

used

with

excellent

results

if

you

use

the

correct

gauge

(thickness).

The

gauge

of

wire

you

need

depends

on

the

distance

the

wire

must

run

from

your

amplifier

to

your

speakers:

Wire

Up

to

8

Up

to

to

20

Almost

any

distance

Gauge

speaker

wire

Special

speaker

cable

Make

sure

that

the

wires

for

both

speakers

are

the

same

length,

even

if

the

distance

from

each

speaker

to

the

amplifier

is

different.

Avoid

coiling

any

excess

speaker

wire

near

the

cables

from

your

components,

since

it

may

degrade

sound

quality

or

cause

hum

or

other

noise

in

the

system.

Speaker

connection:

First,

examine

your

speaker

wire

to

determine

which

lead

to

use

for

the

positive

terminal.

One

of

the

two

leads

will

be

marked

in

some

way,

such

as

being

copper

-colored,

including

a

strand

of

yarn

with

one

conductor,

or

having

a

ridge

or

a

+

symbol

marked

on

the

insulating

material.

Use

the

marked

lead

for

the

positive

(red)

terminal

both

on

the

speaker

and

on

the

back

of

the

amplifier.

1.

Remove

about

3/4

-inch

of

insulation

from

the

end

of

each

speaker

wire.

This

bare

section

of

wire

will

make

the

electrical

connection

with

the

terminals.

2.

Twist

each

lead

so

that

no

loose

strands

stick

out.

3

/

"

3.

Insert

about

1/2

-inch

of

the

wire

that

you

have

identified

as

positive

into

the

red

(+)

connector

on

your

right

-channel

speaker.

Insert

the

other

end

of

this

positive

lead

into

the

RIGHT

(red)

Speaker

1

terminal

on

the

back

of

your

amplifier.

Tighten

the

terminal

knob,

and

the

wire

will

be

held

securely.

4.

Insert

the

other

lead

of

the

same

wire

into

the

black

(-)

connector

on

the

same

speaker.

Insert

the

other

end

of

this

lead

into

the

GND

(black)

Speaker

1

terminal

on

the

back

of

the

amplifier.

The

GND

terminal

is

located

directly

below

the

RIGHT

terminal.

5.

Repeat

the

above

procedure

for

the

left

speaker.

6.

Recheck

the

polarity

of

both

sets

of

speaker

wires,

making

sure

that

you

have

connected

"red

to

red"

and

"black

to

black."

If

you

accidentally

connect

red

to

black,

your

speakers

will

be

out

of

phase.

While

this

will

not

harm

your

system,

your

speakers

will

be

incapable

of

producing

normal

bass

response

until

the

connection

is

corrected.

Setting

the

SPEAKER

OPERATING

MODE

switch:

This

switch,

located

in

the

top

right

corner

of

the

back

panel,

optimizes

the

amplifier

for

the

best

possible

operation

with

your

speakers.

It

is

extremely

important

that

you

set

this

switch

before

playing

your

speakers.

First,

determine

the

impedance

of

your

speakers.

The

impedance

may

be

noted

on

the

back

of

the

speaker

or

in

the

owner's

manual.

If

not,

call

the

dealer

or

manufacturer

to

find

out

the

impedance.
