The

730

has

provision

for

connecting

two

record

playing

units.

All

record

playing

units

provide

two

or

three

cables

(aside

from

the

power

cord)

for

connec-

tion

to

the

730.

These

are

the

left

and

right

channel

signal

cables

and

the

ground

connection.

(Some

turntables

combine

the

ground

connection

with

one

of

the

signal

cables.)

The

two

signal

cables

are

usually

identified

as

"left

channel"

and

"right

channel"

by

a

color

code

or

tabs,

or

the

channel

identifications

are

molded

into

the

insulators

around

the

pin

-type

RCA

connectors.

Determine

which

of

the

cables

is

left

and

which

right

and

insert

them

into

the

two

corresponding

receptacles

on

the

rear

panel

of

the

730

marked

PHONO

1.

Press

them

in

as

far

as

they

will

go

so

they

are

seated

.

snugly.

If

a

separate

ground

wire

is

provided,

connect

its

lug

or

stripped

end

under

the

knurled

nut

marked

GND

on

the

rear

panel

of

the

730.

The

phonograph

signal

connections

are

now

complete.

If

a

second

record

playing

unit

is

to

be

used

connect

it

to

the

PHONO

inputs

in

the

same

manner

as

the

first

unit

was

connected

to

Note:

The

730

is

designed

to

operate

with

a

high

quality

Magnetic

cartridge.

If

you

purchased

your

730

and

turntable

separately,

be

sure

the

turntable

is

equipped

with

a

cartridge

of

this

type.

Insert

the

AC

power

cord

of

your

turntable

into

the

AC

receptacle

marked

UNSWITCHED

on

the

rear

of

the

730.

This

receptacle

is

"live"

so

long

as

the

730

itself

is

connected

to

a

live

AC

outlet,

regardless

of

whether

the

730

is

itself

operating.

Your

turntable

or

automatic

changer

should

be

connected

to

this

receptacle.

A

"T"

-shaped,

folded

dipole

antenna

is

provided

with

the

730

for

FM

reception.

However,

FM

performance

of

the

730

will

be

greatly

enhanced

if

it is

connected

to

an

outdoor

antenna

system.

Many

apartment

buildings

in

urban

areas

provide

a

master

antenna

system

for

television

reception

which

can

often

be

used

for

FM

purposes.

In

some

suburban

and

rural

areas,

cable

television

systems

exist

that

can

also

be

used

for

FM

reception.

In

fact,

television antennas

on

private

houses

are

often

good

for

FM

reception.

Two

types

of

wire,

300

ohm

and

75

ohm,

are

used

as

lead-in

for

outdoor

antenna

systems.

Either

type

can

be

connected

to

the

730.

Find

the

three

-

connector

terminal

strip

on

the

rear

panel

of

the

730

marked

ANTENNA.

If

your

lead-in

is

300

ohm,

it will

be

a

very

flat

wire

with

a

conductor

at

each

edge.

Carefully

cut

about

11

/

2

"

of

the

insulation

material

from

the

center

of

the

lead-in

without

damaging

either

conductor.

Strip

off

about

3

/

4

"

of

insulation

from

each

conductor

and

connect

one

of

them

to

each

of

the

terminals

on

the

three

-

connector

ANTENNA

strip

under

the

bracket

labeled

300,0,.

(The

term

"ohm"

and

thasymbol

"SI"

have

equivalent

meaning.)

If

your

lead-in

is

75

ohm,

you

must

use

a

matching

transformer.

The

lead-in

wire

will

be

a

single

round

wire

with

a

termination

consisting

of

a

metal

connector

with

a

short

length

of

bare,

solid,

copper

-colored

wire

protruding

from

its

center.

This

connector

is

intended

to

be

joined

to

a

7552

to

won

matching

transformer.

These

transformers

are

inexpensive

and

avai

lable

at

many

television

or

electronic

parts

supply

stores.

Once

they

are

joined

to

the

lead-in

they

provide

two

300

ohm

conductors

that

are

connected

to

the

730

as

described

above.

If

your

75.11

lead-in

has

a

bare

end,

the

appropriate

connector

must

be

attached

to

it

so

that

you

can

use

a

matching

transformer.

Where

there

is

only

one

lead-in

and

it

must

supply

signal

for

both

a

television

receiver

and

the

730,

a

"signal

splitter"

or

2

-set

coupler"

can

be

used.

Consult

your

high

fidelity

or

television

dealer

for

information

on

such

devices.

If

no

outdoor

antenna

is

available

to

you,

connect

the

lugs

of

the

dipole

antenna

to

the

30011

terminals.

The

dipole

antenna

will

perform

best

if

its

arms

are

carefully

extended

in

a

straight

line

horizontally,

and

the

entire

antenna

fixed

to

a

wall

or

tacked

to

the

back

of

a

shelf.

Dipoles

are

most

sensitive

on

the

axis

perpendicular

to

the

plane

of

the

two

arms

so

antenna

position

is

important

for

optimum

reception.

which

will
