CONNECTIONS

For

the

moment,

leave

the

power

cord

(1)

of

the

hk670

unconnected.

Put

the

unit

on

the

shelf

or

table

where

it

wil

l

be

instal

led.

Leave

enough

working

space

so

you

can

make

connections

easily.

Al

l

receivers

require

adequate

ventila-

tion.

The

hk670

should

not

be

installed

on

a

cushion

or

rug,

and

a

minimum

of

two

inches'

clearance

should

be

provided

above

and

behind.

Connecting

Speakers

Use

two

-conductor

stranded

wire

to

connect

your

speakers

to

the

receiver.

Eighteen

gauge

lamp

cord

(zip

cord)

is

satisfactory,

but

a

heavier

gauge

(16

or

14

gauge)

is

preferable,

especial

ly

for

distances

over

25

feet.

Cut

two

segments

of

wire

long

enough

to

reach

each

speaker.

Separate

the

conduc-

tors

at

each

end

of

the

wire

segments

for

a

length

of

two

or

three

inches.

Then

carefully

remove

about

one

-quarter

inch

of

insulation

from

each

free

end.

Twist

the

strands

of

each

conductor

so

they

are

smooth

and

tight

with

no

loose

strands.

Lamp

cord

usual

ly

provides

a

"code"

that

differentiates

the

two

conductors.

A

con-

ductor

may

be

coded

by

a

rib,

sharp

corner,

or

indentations

molded

along

the

length

of

the

insulation.

In

some

cases,

a

thin

colored

thread

is

molded

inside

the

insulation

of

one

conductor.

In

others,

one

conductor

is

darker

than

the

other,

or

the

insulation

of

each

con-

ductor

is

of

a

different

color.

Connect

the

bare

ends

of

one

segment

of

lamp

cord

to

your

right

speaker

as

fol

lows:

Connect

the

coded

conductor

to

the

speaker's

positive

("+")

terminal

,

and

the

uncoded

conductor

to

negative

("—").

(The

"+"

and

"—"

markings

are

in

general

use,

although

some

speakers

use

other

labeling

systems,

such

as

"1"

and

"2","A"

and

"B",

and

so

on.)

Find

the

appropriate

row

of

speaker

connectors

on

the

receiver

marked

SYSTEM

1

(2).

Push

in

on

the

red

plastic

head

of

the

connector

marked

RIGHT

to

reveal

an

open-

ing

beneath.

Insert

the

bare

end

of

the

coded

conductor

into

the

opening.

Release

the

con-

nector.

The

conductor

should

now

be

locked

firmly

into

place.

Insert

the

uncoded

con-

ductor

into

the

adjacent

black

connector

marked

GND.

Repeat

the

procedure

for

the

left

speaker,

taking

care

to

observe

the

coding

of

the

conductors

as

described

for

the

right

speaker.

If

the

code

is

followed

as

described,

your

speakers

wi

ll

be

connected

"in

phase",

which

is

important

for

solid

bass

and

precise

lateral

location

of

the

sound

source.

To

connect

a

second

pair

of

speak-

ers,

repeat

the

procedure

for

the

right

and

left

speakers

of

the

second

pair,

using

the

receiver

terminals

marked

SYSTEM

2

(3).

Connecting

AM

Antennas

The

ferrite

loopstick

AM

antenna

(4)

on

the

rear

of

the

hk670

can

be

rotated

to

improve

the

reception

of

distant

stations.

AM

recep-

tion

over

extremely

long

distances

can

be

obtained

with

an

external

"long

wire"

antenna,

which

can

be

connected

to

the

AM

ANTENNA

terminal

(5).

Connecting

FM

Antennas

A

T-shaped

(dipole)

FM

antenna

is

suppl

ied

with

the

receiver.

However,

reception

wil

l

be

greatly

improved

if

the

receiver

is

connected

to

an

outdoor

FM

antenna

system.

If

you

l

ive

in

a

fringe

reception

area,

or

if

your

house

is

situated

among

obstructions

(such

as

moun-

tains

or

tal

l

bui

ldings),

you

may

need

a

pow-

erful

,

directional

FM

antenna.

If

no

outdoor

antenna

is

available,

con-

nect

the

lugs

of

the

dipole

(supplied

with

the

unit)

to

the

FM

30052,

BAL

terminals

(6).

The

dipole

can

then

be

tacked

or

taped

to

a

wal

l

or

the

back

of

a

shelf.

Connecting

Your

Turntable

The

PHONO

inputs

(7)

have

been

designed

to

operate

with

a

high

-quality

magnetic

phono

cartridge.

Do

not

use

a

ceramic

phono

cartridge.

Turntables

are

suppl

ied

with

their

own

signal

cables.

Consult

the

turntable

owner's

manual

and

determine

which

cable

is

for

the

left

channel

and

which

for

the

right.

Insert

the

plugs

of

the

signal

cables

into

the

jacks

on

the

receiver

marked

PHONO,

LEFT

and

RIGHT.

If

the

turntable

has

a

separate

ground

wire,

connect

it

to

the

knurled

lug

on

the

receiver

marked

GND

(8).
