Your

new Reference: by Quadraflex

650FETR

is the first stereo

receiver to utilize special

MOSFET

power

transistors.

These

advanced

devices

reduce

high frequency distortion

to a fraction

of

that found

in

conventional

receivers. The absence of distortion

at

frequencies far beyond

the range of

hearing

assures

a

purity

and clarity

of sound that

is unprecedented.

lntroduction

Your new Reference:650FETR

has

been engineered

by

Quadraflex

to

provide years

of satisfaction.

Proper

installation,

connection and

use of

its

controls

are essential

for

you

to take

full

advantage

of

its

quality

and

versatility. This manual

is

organized

for

your

rapid understanding and

enjoyment of

your

Reference: 650FETR.

U

n

packi

ng

Carefully

remove the

Reference:650FETR

from

its

carton.

Avoid

lifting by

the AM antenna

mounted on the

rear. lt cannot

support

the

weight

of

the

receiver. Save all styrofoam

packing;

it

is

essential

for

secure

shipping or

moving.

There is also a small

plastic

bag containing

a

light

colored

wire.

This is the FM

antenna

so

don't throw

it

away.

Look on

the rear

panel

of

the

650FETR

and

locate the serial

number.

Make sure it

is marked

on

your

dated

purchase

receipt. Save

this to validate ownership

if

your

Reference:650FETR

ever

requires service or

is stolen.

Placement

Place

your

650FETR

on a sturdy

table or shelf,

leaving enough

space to

get

at

its rear

panel

connections.

You

must

allow

several

inches for

ventilation

and

avoid

putting

it on a

rug that

might impede air circulating

into vent openings on

the bottom.

Keep the 650FETR

away

from direct sunlight

or other sources

of

excessive

heat. Avoid

placing

it where

it might

be

exposed to

rain or

moisture.

Before making connections.

make sure the 65OFE1R

is not

yet

plugged

into the

wall. This

must wait until all connections

are

made.

Speaker Connections

For

the

best

performance

we recommend the use of

1B-gauge

"lamp"

or

"zip"

cord. Use

of thinner

wire will impair

power

transfer

to

your

speakers.

Prepare the speaker

wire

by cutting

two approximately

equal lengths and

running them where they

are safe.

At

each

end separate

the

paired

wire for several

inches

and strip aboul1/t

to

% inch

of

insulation at each end.

You can

do this by slightly

cutting the

insulation with a knife or

razor,

being

careful not to cut

into the wire

strands.

Then

pull

off the

unwanted

insulation. Twist the exposed strands

tightly.

You

should

now examine the

wire closely. One side of the

pair

will

either

have a

ridge

on

its insulation or a different color

wire if

the insulation

is transparent. When

you

connect

your

speakers

make sure

the wire with the

ridge or copper color

goes

to the

positive

terminal, usually

marked

+,

8 ohm, or

positive,

and

the

other

wire to the

negative

terminal

usually marked

-

,

0, or

negative. Make sure each

speaker

is wired

the same

way.

Locate the bottom

row of speaker terminals

marked A.

The

two

left-hand terminals are

for the wires

going

to the

speaker on

yout'

right

(as your

face the front of the receiver).

The two right-hand

terminals are

for the speaker on

your

left

(facing

the

receiver).

Connect

each,

remembering

to

insert the coded

wire into the

+

terminal

marked in red on

your

650FETR.

To make connection,

push

on

the tab below each

terminal, insert the

wire into

the

exposed

hole

and

release the tab. At this

point

inspect

your

connections

to make sure that there are

no strands touching

between

wires

or terminals

either at

your

receiver

or

speakers.

You may connect a second

pair

of speakers to the upper

row

of terminals

marked B. Use the same

procedures.

Your

Reference:650FETR can safely operate

two

pair

of speakers

whose impedance

is

8 ohms or

higher.

lf

either

pair

of speakers

is rated

below

8 ohms, then only

one

pair

may be operated at a

time to avoid overloading

the amplifier section.

Caution:

Never make any speaker connections that

join

two

red speaker

terminals on

your

650FETR.

This willcause serious

damage

and

will not increase

power

output.

lf

you

connect only

one

speaker, use

either the L or R terminal, but

not

both.

Turntable

Connection

Make certain

your

turntable

is equipped

with a high

quality

magnetic cartridge.

The two audio cables

attached to the

turntable

will

have

different

color

plugs

to identify L and

R

channels.

Push the

right channel

plug

firmly into the bottom

jack

(R)

on the 650FETR

marked Phono 7 and

the left channel

plug

into the top

jack

(L).

Make sure

they are

pressed

as

far as

they can

go.

Slight twisting

of the

plug

as

it is being

inserted

may be

required if it

is very tight.

Many turntables

also

have a separate

wire that is for

ground-

ing it to the

receiver. Loosen the

metal nut

marked

Gnd on

the

650FETR,

slip

the end of the

ground

wire

under

it,

and

retighten

the nut.

A

second

turntable can

be connected

to the Phono 2

jacks

and

ground

using

the same

procedure.

The

power

cord

from

the turntable

can be

plugged

directly into

the wall or

into the outlet at

the rear of the 650FETR

marked Un-

switched.

This outlet

is

"live"

whenever the 650FETR

is

plugged

into the

wall.
