FM

antenna

supplied

with

your

receiver

should

be

sufficient

for

reception

of

most

stations.

If

you

are

adding

an

external

AM

antenna,

connect

a

ground

wire

to

the

terminal

marked

GND

next

to

the

300

(ohm

mark)

BAL.

NOTE:

Roof

mast

should

be

grounded

directly

to

the

earth

ground

using

10

-gauge

or

heavier

wire,

stand-off

insulators

and

a

metal

stake.

The

FM

antenna

should

then

be

connected

to

the

ground

mast

via

an

antenna

discharge

unit).

The

quality

of

your

FM

and

AM

reception

is

directly

propor-

tional

to

the

quality

of

the

antenna

you

use.

If

you

live

in

a

"problem"

area

or

are

simply

interested

in

better

reception,

please

refer

to

APPENDIX!!

in

this

manual.

Cabling.

For

optimal

sonic

performance,

you

should

use

the

highest

quality

speaker

cables

you

can

afford.

However,

common

"zip

cord"

from

a

hardware

store

can

be

employed

if

care

is

taken

to

use

the

proper

gauge.

This

will

depend

on

the

distance

from

your

receiver

to

your

speakers.

Use

the

following

chart

as

a

guide:

Make

that

both

right

and

left

speaker

wires

are

the

same

length,

even

if

the

distance

from

amp

to

each

speaker

is

different.

Also,

avoid

coiling

any

excess

wire

near

or

with

cords,

especially

the

from

Connection.

First,

determine

the

polarity

of

your

speaker

wires.

If

you

are

using

zip

cord,

they

may

1)

be

different

colors,

such

as

silver

and

copper

-colored,

2)

have

a

series

of

ridges

on

one

conductor,

or

3)

include

a

strand

of

yarn

with

one

conductor.

Note

that

the

terminals

for

both

SPEAKER

SYSTEM

1

and

SPEAKER

SYSTEM

2

are

marked

LEFT

and

RIGHT

with

GND

(ground)

terminals

in

between.

A

good

practice

is

to

use

the

red/copper/ridged/yarn

conductor

for

the

(positive)

conductors

on

both

receiver

and

speaker

terminals.

Use

the

black/silver/

non-ridged/no-yarn

conductor

for

the

GND

(negative)

connection.

1.

Strip

1/2

inch

of

conductor

off

each

speaker

conductor.

2.

Twist

the

individual

strands

together

so

that

no

loose

strands

stick

out.

3.

Taking

care

to

maintain

proper

polarity

(positive

to

positive/

negative

to

negative),

insert

1/2"

of

conductor

into

the

hole

in

each

speaker

terminal

connector.

Remember,

even

one

loose strand

touching

another

connector

can

cause

a

short

circuit.

4.

If

you're

using

two

sets

of

speakers,

repeat

these

connections

for

the

second

pair

of

loudspeakers,

using

SPEAKER

SYSTEM

2

terminals.

5.

Recheck

the

polarity

of

both

sets

of

speaker

wires,

making

sure

that

you

have

connected

"red

to

red"

and

"black

to

black".

While

the

HK550Vxi

and

HK440Vxi

are

equipped

to

let

you

operate

two

sets

of

loudspeakers

at

once,

the

impedance

of

each

set

of

speakers

is

very

important.

If

you

are

intending

to

use

two

sets

of

speakers,

please

consult

APPENDIX!

--

Multiple

Speakers

in

Parallel

before

proceeding

with

the

Speaker

Operat-

ing

Mode

setting.

Both

the

HK550Vxi

and

HK440Vxi

have

a

special

selector

switch

that

optimizes

the

receiver's

amplifier

section

for

best

operation

with

your

individual

speakers.

It

is

very

important

that

you

set

this

switch

before

playing

your

speakers.

Determining

the

impedance

of

your

speakers.

For

proper

performance,

you

must

set

the

SPEAKER

OPERATING

MODE

switch

to

correspond

with

the

impedance

load

of

your

loudspeakers.

If

you

know

the

impedance

of

your

speakers

(generally

4 or

8

ohms),

then

proceed

to

Setting

the

Switch.
