FM

ANTENNA

CONNECTIONS

There

are

two

methods

you

can

use

when

connecting

the

FM

antenna

to

the

antenna

input

terminals:

you

can

use

a

300-ohm

twinlead

feeder

or

a

75-ohm

coaxial

cable.

Pioneer

recommends

the

75-ohm

coaxial

cable

(RG59U,

etc.)

if

you

want

your

receiver

to

display

its

capabilities

to

the

full.

The

coaxial

cable

is

more

effective

than

the

twin-

lead

feeder

in

safeguarding

against

external

interference

noise

from

impairing

the

sound

quality.

In

other

words,

twinlead

feeders

are

liable

to

pick

up

external

noise,

and

this

is

why

they

are

not

recommended.

Connections

using

a

75-ohm

coaxial

cable

Refer

to

Fig.

1

and

follow

the

procedure.

Prepare

the

tip

of

the

coaxial

cable

and

connect

it

to

the

INSTALLATION

GROUNDING

It

is

recommended

that

the

unit

be

grounded

if

FM

recep-

tion

is

accompanied

by

a

great

deal

of

noise

or

interference.

To

ground,

connect

a

thick

vinyl-covered

wire

to

the

GND

terminal

at

one

end;

at

the

other

end,

wind

the

wire

around

a

metal

water

pipe,

grounding

rod

or

copper

plate

and

bury

it

in

the

ground.

NOTE:

Never

connect

the

grounding

wire

to

a

gas

pipe

since

there

may

be

an

explosion

if

leaks.

change

the

direction

of

the

(and

this

will

To

achieve

optimum
