HK6850

and

HK6950R

Connections

If

you

are

using

a

single

set

of

8

-ohm

speakers,

remove

the

screw

and

the

plate

covering

one

side

of

the

switches.

Set

both

of

the

SPEAKER

OPERATING

MODE

switches

to

852

position

and

replace

the

plate

so

that

it

covers

the

other

side

of

the

switches.

In

all

other

cases,

use

the

4S2

positions.

If

you

are

in

doubt

about

the

impedance

of

your

speakers,

use

the

4

-ohm

positions,

since

the

power

amplifier

runs

cooler

in

this

mode.

Having

these

switches

set

to

852

if

you

are

using

4

-ohm

or

6

-ohm

speakers

may

result

in

overheating

of

the

amplifier

or

failure

of

an

internal

fuse.

If

you

are

using

two

pairs

of

speakers,

it

is

important

to

note

that

the

combined

total

impedance

of

both

sets

of

speakers

must

not

be

less

than

4

ohms.

If

the

combined

impedance

is

lower,

you

may

overload

the

amplifier,

resulting

in

overheating

or

failure

of

an

internal

fuse.

Two

sets

of

8

-ohm

speakers

presents

a

combined

total

impedance

of

4

ohms,

which

is

an

acceptable

load

for

your

amplifier

as

long

as

you

set

the

SPEAKER

OPERATING

MODE

switches

to

4

ohms.

If

you

have

questions,

consult

your

Harman

Kardon

dealer

before

adding

a

second

set

of

speakers

to

your

system.

Connecting

a

turntable

Your

HK6850

or

HK6950R

has

two

sets

of

PHONO

input

jacks

for

connecting

turntables.

One

set

of

jacks

is

marked

MC,

for

Moving

Coil.

If

you

have

a

moving

coil

cartridge

that

generates

at

least

120μV

mounted

on

your

turntable,

be

sure

you

connect

the

turntable

to

the

MC

jacks.

These

jacks

are

internally

wired

to

a

special

step-up

amplifier

stage.

MC

MM

0.0

NO

LE(

RIGHT

.

GND

The

other

set

of

jacks

is

marked

MM,

for

Moving

Magnet.

If

you

have

a

regular

moving

magnet

car-

tridge

mounted

on

your

turntable,

connect

the

turn-

table

only

to

the

MM

inputs,

as

the

sizeable

volume

boost

of

the

MC

jacks

will

cause

volume

problems

and

severe

distortion.

Make

sure

you

connect

the

thin

ground

wire

from

your

tuntable

to

the

GND

post

located

next

to

the

phono

input

jacks.

Failure

to

connect

this

ground

wire

can

result

in

a

distracting

hum

when

you

play

your

turntable.

When

only

one

turntable

is

used,

be

sure

to

insert

the

attached

shorting

pin

plug

into

the

PHONO

MM

or

MC

jacks

that

are

not

being

used.

Connecting

a

CD

player

Attach

the

patch

cord

from

the

CD

input

jacks

to

your

compact

disc

player.

Connecting

a

tuner

Attach

the

patch

cord

from

the

TUNER

input

jacks

to

your

tuner.

Be

sure

you

connect

an

antenna

to

your

tuner;

otherwise,

the

quality

of

your

AM

and

FM

signal

may

be

poor.

Connecting

a

tape

deck

You

can

have

several

tape

decks

connected

to

your

HK6850

or

HK6950R.

The

best

choice

is

to

connect

your

tape

deck(s)

to

the

jacks

labeled

TAPE

1

or

TAPE

2.

The

IN

and

OUT

connectors

on

your

tape

deck

correspond

to

the

opposite

connectors

on

the

back

of

your

amplifier.

That

is,

you

connect

OUT

on

the

tape

deck

to

IN

on

the

amplifier.

A

third

tape

deck

can

be

connected

to

the

AUX

connectors

if

the

deck

will

be

used

only

for

playback.

Connect

a

patch

cord

from

the

audio

OUT

connectors

on

the

tape

deck

to

the

AUX

connectors

on

your

HK6850

or

HK6950R.

Note

that

the

TAPE

input

jacks

can

be

used

for

connecting

either

a

tape

deck

or

a

other

video

source.

Video

equipment

connection

is

described

in

the

following

sections.

Connecting

a

video

product

Connect

a

patch

cord

from

the

audio

out

connec-

tors

on

your

video

product

to

the

video

audio

connec-

tors.

Connecting

an

external

power

amplifier

If

you

want

to

use

your

HK6850

or

HK6950R

simply

as

a

preamplifier

and

connect

it

to

an

external

power

amplifier,

use

the

PRE

-OUT

connectors

in

the

upper

-left

corner.

Connect

the

patch

cord

from

the

PRE

-OUT

jacks

on

the

HK6850

or

HK6950R

to

the

jacks

on

your

external

power

amplifier.

Then

connect

your

speakers

to

your

external

power

amplifier.

Connecting

an

external

preamplifier

To

use

the

HK6850

or

HK6950R

simply

as

a

power

amplifier,

connect

the

Pre

-Out

jacks

of

the

external

preamplifier

to

the

Main

-in

jacks

on

the

back

panel

of

the

HK6850

or

HK6950R.

Then

set

the

"Integrated

-Separate"

switch

on

the

back

panel

to

the

"Separate"

position.

Wired

Remote

Control

To

control

your

amplifier

with

an

external

infrared

remote

sensor,

connect

the

wire

from

the

remote

sensor

to

the

"Remote

In"

jack

on

the

back

panel.

Or,

if

you

have

a

stereo

component

with

a

built-in

infrared

remote

sensor

and

a

"Remote

Output"

jack,

it

may

be

possible

to

connect

this

jack

to

the

"Remote

In"

jack

of

your

amplifier.

All

Harman

Kardon

products

with

"Remote

In"

and

"Remote

Out"

jacks

are

compatible

with

one

another,

except

for

the

Citation

22,

24

and

25.

Other

manufacturers'

remote

sensors

may

not

be

compatible,

but

it

will

not

hurt

to

experiment.

A

second

wire

may

be

used

to

connect

your

amplifier's

"Remote

Out"

jack

to

the

"Remote

Input"

of

another

stereo

component.

Continue

this

process

to

include

additional

components

(if

compatible).

To

control

your

amplifier,

you

may

use

the

remote

control

supplied

with

the

HK6950R.

Or

you

may

use

a

universal

remote

control

unit,

such

as

Harman

Kardon's

MasterworksTm

,

which

can

also

control

other

components,

such

as

TVs,

VCRs,

tape

decks

and

CD

players.

Masterworks

is

available

from

your

Harman

Kardon

dealer.
